Object locations (PNG image format) used for synthetic aperture sonar (SAS) data
- Author(s): Philtron, Jason; Johnson, Shawn; Brown, Daniel
- Description: The simulated synthetic aperture sonar (SAS) data presented here was generated using PoSSM [Johnson and Brown 2018]. The data is suitable for bistatic, coherent signal processing and will form acoustic seafloor imagery. Included in this data package is simulated sonar data in Generic Data Format (GDF) files, a description of the GDF file contents, example SAS imagery, and supporting information about the simulated scenes. In total, there are eleven 60 m x 90 m scenes, labeled scene00 through scene10, with scene00 provided with the scatterers in isolation, i.e. no seafloor texture. This is provided for beamformer testing purposes and should result in an image similar to the one labeled "PoSSM-scene00-scene00-starboard-0.tif" in the Related Data Sets tab. The ten other scenes have varying degrees of model variation as described in "Description_of_Simulated_SAS_Data_Package.pdf". A description of the data and the model is found in the associated document called "Description_of_Simulated_SAS_Data_Package.pdf" and a description of the format in which the raw binary data is stored is found in the related document "PSU_GDF_Format_20240612.pdf". The format description also includes MATLAB code that will effectively parse the data to aid in signal processing and image reconstruction. It is left to the researcher to develop a beamforming algorithm suitable for coherent signal and image processing. Each 60 m x 90 m scene is represented by 4 raw (not beamformed) GDF files, labeled sceneXX-STARBOARD-000000 through 000003. It is possible to beamform smaller scenes from any one of these 4 files, i.e. the four files are combined sequentially to form a 60 m x 90 m image. Also included are comma separated value spreadsheets describing the locations of scatterers and objects of interest within each scene. In addition to the binary GDF data, a beamformed GeoTIFF image and a single-look complex (SLC, science file) data of each scene is provided. The SLC data (science) is stored in the Hierarchical Data Format 5 (https://www.hdfgroup.org/), and appended with ".hdf5" to indicate the HDF5 format. The data are stored as 32-bit real and 32-bit complex values. A viewer is available that provides basic graphing, image display, and directory navigation functions (https://www.hdfgroup.org/downloads/hdfview/). The HDF file contains all the information necessary to reconstruct a synthetic aperture sonar image. All major and contemporary programming languages have library support for encoding/decoding the HDF5 format. Supporting documentation that outlines positions of the seafloor scatterers is included in "Scatterer_Locations_Scene00.csv", while the locations of the objects of interest for scene01-scene10 are included in "Object_Locations_All_Scenes.csv". Portable Network Graphic (PNG) images that plot the location of objects of all the objects of interest in each scene in Along-Track and Cross-Track notation are provided. DOI: 10.60521/331901
Beamformed GeoTIFF images of synthetic aperture sonar (SAS) data
- Author(s): Philtron, Jason; Johnson, Shawn; Brown, Daniel
- Description: The simulated synthetic aperture sonar (SAS) data presented here was generated using PoSSM [Johnson and Brown 2018]. The data is suitable for bistatic, coherent signal processing and will form acoustic seafloor imagery. Included in this data package is simulated sonar data in Generic Data Format (GDF) files, a description of the GDF file contents, example SAS imagery, and supporting information about the simulated scenes. In total, there are eleven 60 m x 90 m scenes, labeled scene00 through scene10, with scene00 provided with the scatterers in isolation, i.e. no seafloor texture. This is provided for beamformer testing purposes and should result in an image similar to the one labeled "PoSSM-scene00-scene00-starboard-0.tif" in the Related Data Sets tab. The ten other scenes have varying degrees of model variation as described in "Description_of_Simulated_SAS_Data_Package.pdf". A description of the data and the model is found in the associated document called "Description_of_Simulated_SAS_Data_Package.pdf" and a description of the format in which the raw binary data is stored is found in the related document "PSU_GDF_Format_20240612.pdf".

3D P-wave velocity model of the Alaska Peninsula subduction zone from the AACSE active-source data set
- Author(s): Acquisto, Tanner; Becel, Anne; Canales, JuanPablo; Beauce, Eric
- Description: This is a 3D, P-wave, crustal-scale velocity model of the Alaska subduction zone that encompasses both the incoming and overriding plates and spans the Semidi segment and the SW Kodiak aspertiy. This model was derived from the traveltime inversion of first-arrivals interpreted from active-source ocean bottom seismometer data and onshore seismometer data acquired as part of the Alaska Amphibious Community Seismic Experiment (AACSE; MGL1903). The model also incorporates data from the 2D OBS profile AL03 acquired as part of the Alaska Langseth Experiment to Understand the MegaThrust (ALEUT; MGL1110) and vertical-component data from TA and AEC stations located on the Alaska Peninsula, Kodiak Island (S19K), and the smaller Sitkinak (SII), Chirikof (CHI), and Shumagin Islands (CHN). We interpreted 42,103 first-arrivals out of 609,915 available traces with 32,024 (76%) coming from 37 of the AACSE instruments, 3,541 (8%) from the 3 AEC instruments, and 6,538 (16%) from the 20 instruments in the AL03 data set. The seismic velocity model file is in ASCII CSV format with a header for each column. The seismic velocity model contains six columns as follows: longitude, latitude, Z in km, model seafloor depth in km, P-wave velocity in km/s, and standard deviation in km/s. The sea surface is set to Z=0, meaning negative Z values indicate topography or air (i.e., above sea level). The model coordinates have been rotated and converted back to latitude and longitude. The model has been regridded to a uniform spacing of 0.25 degrees in lat/lon and 0.5 km in depth. The dimensions of the model are 227 by 446 by 86 in latitude, longitude, and depth (km), respectively. The water velocity is set to 1.5 km/s and the air velocity is 0.33 km/s. Voxels outside of the original rotated model space contain NaN values for P-wave velocity and standard deviation. The starting P-wave velocity model was created from the results of a 2D traveltime inversion of the 2D AL03 data. To create the final model, we performed a Monte Carlo analysis by creating 50 perturbed starting models, adding random Gaussian noise to the traveltime data, and inverting the data with the same forward calculation and regularization parameters. The final Vp model is the average of the 50 ensembles, which has a mean standard deviation of 0.041 km/s within the overlapping regions of ray coverage. The associated navigation files contain the source and receiver locations used in this study. Funding to create this velocity model was provided through NSF grants OCE-1947758 and OCE-1948087.

Source/receiver navigation files for the 3D P-wave velocity model of the Alaska Peninsula subduction zone from the AACSE active-source data set
- Author(s): Acquisto, Tanner; Becel, Anne; Canales, JuanPablo; Beauce, Eric
- Description: These navigation files give the source and receiver locations for the associated 3D, P-wave, crustal-scale velocity model of the Alaska subduction zone that encompasses both the incoming and overriding plates and spans the Semidi segment and the SW Kodiak aspertiy. Both navigation files are in ASCII CSV format, with the first column being either the OBS name or shot number, followed by receiver/source project name (AACSE, AEC, or AL03), latitude, longitude, and Z-coordinate (in km). Funding to create this velocity model was provided through NSF grants OCE-1947758 and OCE-1948087. DOI: 10.60521/331830

Miniature Autonomous Plume Recorder (MAPR) data acquired at Hunga volcano, Kingdom of Tonga, in July-August 2022 during phase 2 of the Tonga Eruption Seabed Mapping Project (TESMaP-2)
- Author(s): Walker, Sharon; deRonde, Cornel
- Description: The second phase of the Tonga Eruption Seabed Mapping Project (TESMaP-2) utilized the uncrewed surface vessel (USV) Maxlimer (Sea-Kit International) to conduct remotely-operated surveys of the Hunga volcano seven months after the powerful explosive eruption of 15 January 2022. A custom-built cage and winch with 300 m of non-conducting cable were added to the USV Maxlimer payload to accommodate Miniature Autonomous Plume Recorder (MAPR) instruments, and used to map hydrothermal and volcanic plumes within the crater at Hunga volcano. The MAPR data files are in ASCII comma-delimited format that contains the date/time (UTC), pressure (db), depth (m), temperature (°C), turbidity (optical backscatter, NTU) and oxidation-reduction potential (E, mV) measurements from 29 vertical casts and 8 tow-yo operations that were conducted during TESMaP-2. Methods and results are published in Walker and de Ronde (2024). Unique to this project, this was the first time that standard vertical cast and tow-yo operations were conducted from an uncrewed surface vessel being operated remotely 16,000 km distant from the study site. USV Maxlimer was launched from Nuku'alofa, Kingdom of Tonga and MAPR operations occurred between 27 July 2022 and 29 August 2022. TESMaP-2 was funded by The Nippon Foundation and GEBCO-Seabed2030, with additional support for MAPR operations from NOAA-PMEL Earth-Ocean Interactions program and GNS Science, New Zealand.

Processed Ocean Bottom Hydrophone (OBH) travel-time picks from the Great Meteor seamounts, northeast Atlantic Ocean (R/V Meteor, 1990)
- Author(s): Grevemeyer, Ingo; Watts, Anthony
- Description: The OBH data was acquired along five ~200 km-long profiles during R/V METEOR cruise No. 12/2 in the summer of 1990. Navigation during the cruise was controlled by the Global Positioning System (GPS). R/V Meteor was equipped with a source array of four 19-litre airguns, providing a total volume of 76 litres. Guns were towed at a depth of ~8 m and fired every 2 minutes at a pressure of ~140 bars, providing a dominant source frequency of 6 Hz. The OBH instruments were a prototype supplied by University of Hamburg and used in conjunction with University of Bergen air guns. The continuously-recorded analogue data were digitized at 100 samples per second and stored on Exabyte tapes. The digitised data was reprocessed in 2022/2023 using a predictive deconvolution and a simple Butterworth bandpass filtered from 4 to 15 Hz, and stored in SEG-Y file format. SEG-Y files have been reduced by 8 km/s. Record sections start at t = 0. The travel-time data of the main refraction branches were generated by hand-picking first breaks on OBH record sections. The first breaks were then compared to predictions based on tomographic models of the P-wave velocity structure of the oceanic crust and upper mantle along each profile of the Great Meteor Seamounts. The travel-time pick files are one of the inputs into the 2-D ray-tracing program RAYINVR (https://terra.rice.edu/department/faculty/zelt/rayinvr.html). The travel-time picks data files are in ASCII format and contain the observed travel time-distance pairs in the following format: [1] (First line) the x-coordinate (km) of the shot point, 1 if the receivers are to the right of the shot point or -1 if the receivers are to the left, 0, and 0 (format: 3F10.3, I10). [2] (Second line) the x-coordinate (km) of the observed data, the corresponding unreduced travel time (s), the estimated uncertainty of the travel time pick (s), and a non-zero integer used to identify the type of arrival to allow for the appropriate comparison with the rays traced (format: 3F10.3, I10). Line [2] is repeated for each pick corresponding to the shot point in line [1]. The sequence [1] and [2] is repeated for each shot point of the data set. [3] The file is terminated with the following line: 0, 0, 0, -1 (format: 3F10.3, I10). The data was collected under Deutsche Forschungsgemeinschaft grant We 690/27 1-4. DOI: 10.60521/331766

SEG-Y files have been reduced by 8 km/s. Record sections start at t = 0. The "station_and_profile_coordinates.txt" file is in ASCII format and contains three groups of navigation data, as follows. The first group presents the coordinates (lon/lat) of the start and end of five profiles that were shot during Meteor M12-2. The second group gives the coordinates (lon/lat) of the OBHs where reprocessed SEG-Y-formatted data files are available. The final group provides the coordinates (lon/lat) of the OBHs where reprocessed travel-time pick files are available. The data was collected under Deutsche Forschungsgemeinschaft grant We 690/27 1-4. DOI: 10.60521/331768

- Description: This data set was generated as part of the 2010 GUlf of Mexico Basin Opening (GUMBO) program that collected wide-angle seismic refraction profiles in the northern Gulf of Mexico to better constrain crustal structure in the region.This data set presents the seismic P-wave velocity model for the eastern profile, GUMBO line 4, which extends for a distance of 507 km from offshore northwestern Florida, across the continental shelf and Florida Escarpment, and into the central Gulf of Mexico. The velocity model is in GMT-compatible netCDF grid format. The x-coordinate is profile distance in km (grid interval 0.2 km), the y-coordinate is depth in km (grid interval 0.1 km), and the z-values are P-wave velocities in km/s. The GUMBO seismic refraction survey was conducted during late 2010 using M/V Iron Cat operated by Reservoir Geophysical. The project was funded through ExxonMobil. DOI: 10.60521/331762

Processed CTD data acquired from 15-18°S along the Southern East Pacific Rise (SEPR) during R/V Roger Revelle cruise RR2106 (2021)
- Author(s): Walker, Sharon; Resing, Joseph; Bundy, Randelle; Charette, Matthew; German, Christopher
- Description: This data set was acquired during cruise RR2106 using 3 separate CTD systems (referred to as "Hydrothermal", "Trace Metal", and "Pump") that all utilized Seabird 911plus CTD systems with various integrated analog sensors (see the associated documentation that identifies the instrument configuration of each system). The data files are in ASCII format and column headers define the fields. Navigation is included in the files. The aim of the study was to evaluate the contribution of low-temperature hydrothermal venting as an important, but overlooked, source of stabilized dissolved iron to the ocean. Operations included near-bottom (20-40 m above the seafloor) CTD tows (using the "Hydrothermal" CTD only) along with vertical casts that were completed using all 3 systems. The CTD data has been processed using Seabird Data Processing modules and averaged to 5-second intervals. Navigation for the tows was calculated using a lay-back method. Primary plume tracers are potential temperature anomaly (ΔTheta, °C), turbidity anomaly (optical backscatter, ΔNTU), and oxidation-reduction potential anomaly (ΔE, mV). Users should refer to the continuous CTD data files (i.e., those with "CTDdata" in the file names) for ΔTheta and ΔE values at the time the bottle samples were obtained; ΔNTU values are included in the "BottleFile" files, which are subsets of the continuous data from the times each bottle sample was obtained (generated by Seabird Data Processing "Bottle Summary" module). The data set was generated as part of the projects called "Are Low-Temperature Hydrothermal Vents an Important but Overlooked Source of Stabilized Dissolved Iron to the Ocean?" and "Low temperature hydrothermal vent fluxes as traced by radium isotopes". Funding was provided by NSF awards OCE17-56402 and OCE18-29431. DOI: 10.60521/331701

Multi-Resolution bathymetry grids of the Naples and Pozzuoli Gulf and the Amalfi Coastal Area collected during cruise Jamme_Gaia22, 2022
- Author(s): Foglini, Federica; Tonielli, Renato; Rovere, Marzia
- Description: During the Jamme_Gaia22 cruise, held from September 27th to October 20th, 2022, multi-beam data were collected using three different MBES systems: the Kongsberg EM2040-04 MKII (0.4° x 0.7°) for water depths between 50 and 150 meters, the Kongsberg EM712 (0.5° x 1°) for depths between 150 and 1000 meters, and the Kongsberg EM304 MKII (1° x 1°) for depths greater than 1000 meters. The raw data were processed using QPS Qimera v.2.5.0 software (Quality Positioning Services BV, Zeist, Netherlands), following standard procedures that included sound speed correction, removal of erroneous soundings, and correction of vertical offsets. GeoTIFF surfaces were generated at resolutions determined based on water depth and the footprint of each sonar system used as follows: 2m for depth 50-120m; 5m for depth 100-200m; 15m for depth 480-700m; 20m for depth 680-1000m; 30m for depth 980-1300m; 40m for depth 1280-2800m. The bathymetry grids are in GeoTIFF grid format. DOI: 10.60521/331667
Multi-Resolution backscatter grids of the Naples and Pozzuoli Gulf and the Amalfi Coastal Area collected during cruise Jamme_Gaia22, 2022
- Author(s): Foglini, Federica; Tonielli, Renato; Rovere, Marzia
- Description: During the Jamme_Gaia22 cruise, held from September 27th to October 20th, 2022, multi-beam data were collected using three different MBES systems: the Kongsberg EM2040-04 MKII (0.4° x 0.7°) for water depths between 50 and 150 meters, the Kongsberg EM712 (0.5° x 1°) for depths between 150 and 1000 meters, and the Kongsberg EM304 MKII (1° x 1°) for depths greater than 1000 meters. The MBES backscatter data were processed using QPS Fledermaus Geocoder Tool (FMGT) v.7.10.2. The processed data (.gsf) underwent backscatter corrections, beam pattern correction, and angle-varying gain (AVG) adjustments. FMGT then utilized the sonar’s navigation data (including XY coordinates, roll, heading, pitch, and heave) to enhance spatial accuracy. The bathymetric Digital Terrain Model (DTM) generated in Qimera was used as a reference grid to further refine backscatter corrections by determining the topographic slope. The corrected bathymetry from the source files (GSF) was used to accurately geo-reference snippet traces from single pings to the seafloor with correct scaling. Finally, the backscatter snippets were mosaicked using the "No Nadir possible, 25% overlap" algorithm to reduce banding, and 30-40% line blending was applied to blend overlapping pixels. The mosaics were gridded at various resolutions, with dB values cropped to ± 3σ and mapped to an 8-bit scale. The final mosaics were exported as "One merged Colored GeoTIFF format". The backscatter grids are in ESRI ASCII grid format. DOI: 10.60521/331668
Depth to top of subducting Juan de Fuca/Gorda/Explorer plate crust and plate boundary fault within the offshore Cascadia seismogenic zone, 42°N to 50°N
- Author(s): Carbotte, Suzanne; Boston, Brian; Han, Shuoshuo; Canales, JuanPablo; Shuck, Brandon; Tobin, Harold; Beeson, Jeffrey; Nedimovic, Mladen
- Description: The two gridded surfaces in this data set correspond to depth in meters from the sea surface to Top of igneous Oceanic Crust (TOC) (file "Casie21-R2T-TOC_medflt-surface-mask.grd”) and to the interpreted plate boundary/megathrust fault (file "Casie21-R2T-PlateBdy_medflt-surface-mask.grd”) derived from CASIE21 and Juan de Fuca Ridge2Trench 2D long-offset multi-channel seismic (MCS) data. These MCS data were acquired using the R/V Marcus G. Langseth during two cruises: MGL2104 and MGL1211. The combined seismic coverage provides a quasi-regular grid of margin-perpendicular and margin-parallel seismic lines spaced ~50-75 km apart spanning the margin. All seismic sections are processed to Pre-Stack Depth Migration (PSDM) using the same processing scheme and parameters (see processing report and PSDM sections available at doi:10.26022/IEDA/331274 and doi:10.60521/331457). The TOC crust horizon is identified from PSDM sections based on reflection characteristics including amplitude, wavelength/frequency, and continuity. Moho reflections and other intra-crustal reflectivity are used to aid in TOC interpretations assuming a ~6 km thick oceanic crust. The plate boundary/megathrust fault is identified from the geometry and depth extent of thrust faults of the accretionary wedge as well as the geometry of deep sediment horizons and is well-constrained near the deformation front along all seismic lines crossing the margin. Observations of changes in TOC reflectivity beneath interpreted deeper sediment décollements further support interpretations. Estimated depth uncertainties for TOC and plate boundary fault picks from the seismic sections are +/- 100m on the incoming plate and are up to +/- 1km under the shelf. The TOC and plate boundary fault picks from all seismic lines are smoothed and gridded using the GMT algorithm “surface". Further descriptions of seismic data interpretation and gridding parameters used to derive the gridded surfaces are provided in Carbotte et al. Science Advances, 2024, at doi:10.1126/sciadv.adl3198; gridded TOC and plate boundary fault surfaces are visualized in Figs. 2A and 7A in that publication. The grids are in GMT-compatible netCDF format, with positive downwards. DOI: 10.60521/331666

Onshore-offshore phase velocity maps from Cascadia Initiative data
- Author(s): Janiszewski, Helen; Gaherty, James; Abers, Geoffrey; Gao, Haiying; Eilon, Zach
- Description: This data set contains phase velocity maps calculated from vertical component ambient noise cross correlations, and Helmholtz tomography of teleseismic earthquake Rayleigh waves. These are calculated from seismic stations deployed as part of the Cascadia Initiative program. Tilt and compliance corrections have been applied to the teleseismic earthquake data from OBS instruments prior to analysis. For the ambient noise data, phase velocity maps are calculated for 9, 10, 11, 12, 13, 14, 15, 17.5, and 20 s period. For the Helmholtz tomography, results are given at 20, 25, 32, 40, 50, 60, 80, 100, 115, 130, 145, and 160 s period. The data are given in ASCII format where the first column is latitude, the second is longitude, the third is phase velocity in km/s, and the fourth is the uncertainty for phase velocity in km/s. The value 999.000000 designates a NaN for that grid cell. Each of the .xyz files contains information for the phase velocity maps at each period. The files are either named ambphv_* or helmholtz_* designating which data set was used to calculate the results. That is, ambphv_* is calculated from ambient noise cross correlations, while helmholtz_* uses teleseismic earthquake Rayleigh waves in Helmholtz tomography. The number ending each file name indicates the period band for each file in seconds. The data files were generated as part of a project called Thermal structure, hydration and dehydration of the entire Juan de Fuca Plate. Funding for this project came from NSF grant OCE13-34831. The data set is referenced in Janiszewski et al., 2019; details related to processing steps and phase velocity map calculations can be found therein. DOI: 10.60521/331658

Seismic velocity grid, Alaska Langseth Experiment to Understand the megaThrust (ALEUT) Line 5, cruise MGL1110
- Author(s): Shillington, Donna; Becel, Anne; Nedimovic, Mladen
- Description: This is a 2D P-wave velocity model along Alaska Langseth Experiment to Understand the megaThrust (ALEUT) Line 5, which crosses the Alaska subduction zone within the Shumagin segment. The model is constrained by travel time tomography of active-source seismic data recorded on ocean bottom seismometers and one onshore seismic station. The modeled region includes the incoming Pacific plate and the overriding North American plate. Other details can be found in Shillington et al., GRL, 2022. The P-wave velocity model is in GMT-compatible netCDF grid format in which the gridded values are stored as follows: distance along the line (x, km); depth (z, km); P-wave velocity (km/s). The model is masked where there is no ray coverage. The lat/lon end points of the line are: x=0 at latitude 52.452656N/longitude 159.477966W; and x=335 at latitude 55.3492N/longitude 160.885W. This data set was generated as part of the projects called "The Aleutian megathrust from trench to base of the seismogenic zone; integration and synthesis of laboratory, geophysical and geological data"; and, "Megathrust seismic hazards by reflection mapping". Funding was providing through NSF awards OCE09-26614 and EAR13-47312. DOI: 10.60521/331651

Raw single-channel seismic reflection images from the Red Sea (RC0911A, 1965)
- Author(s): Mitchell, Neil
- Description: Scientists aboard R/V Robert Conrad, led by Tom Aitken, collected single-channel analogue seismic reflection data during cruise RC0911A in 1965 with a 25 cubic-inch airgun and short hydrophone streamer. Despite their age, the data have good resolution. They reveal seismic stratigraphy within the Plio-Pleistocene sediments overlying the "S-reflection", which is commonly taken to mark the top of the Miocene evaporites in the Red Sea or perhaps a little above them. The data in places also reveal some of the uppermost layered Miocene evaporites, erosional unconformities at the S-reflection and possible salt diapirs. The seismic profiles extend from the entrance to the Bab el Mandeb Strait in the Gulf of Aden to the Gulf of Suez. Data quality deteriorates towards the northern end of the transect. Electrical recordings from the hydrophone streamer were recorded in two channels onto paper (one with high amplifier gain and one with low amplifier gain). Navigation is unknown though likely combined celestial and dead-reckoning. The paper sheets were scanned by Neil Mitchell at Lamont in June 2014 with the help of Rose Anne Weissel. Individual data sheets were too big for the scanner (a 600 dpi Tokia photocopier). So, each sheet was scanned twice, covering both ends of each sheet. The dates are given at the base of each sheet and are in day-month-year format (with the month given in Roman numerals). Other annotation, such as times of vessel alter course (A/c) and coring stations, are also given at the base of each sheet. Annotated times are local, not UTC. The time offset appears to be 3 hours (ship time was 3 hours ahead of UTC). The time conversion may be checked by comparing the seabed profile against that in GeoMapApp (the "Blue book" version of the data under Portals > "Analog Seismic Reflection Profiles" menu is correctly aligned) or against the bathymetry in MGD77 files. Horizontal lines on the sheets are at every 0.5 seconds of Two-Way Travel Time (TWTT). These images are in JPEG image format (greyscale), and the files are in image pairs, labelled a and b, with one a/b pair corresponding to one seismic reflection data sheet. The numerical parts of the file names are in sequence following the survey time, hence the first file, RC0911A_01a, was collected at the start of the survey near the Bab el Mandeb Strait in the south. Higher file numbers are progressively further north, until RC0911A_45a, which was collected in the Gulf of Suez at the end of the survey. DOI: 10.60521/331614

Processed multibeam bathymetry and acoustic backscatter data from the southern Mid-Atlantic Ridge, 50.2°S-51.5°S (RR2301, 2023)
- Author(s): Parnell-Turner, Ross
- Description: A bathymetric survey was completed using a Kongsberg EM124 echosounder along the Mid-Atlantic Ridge and its flanks between 50.2 and 51.5°S during the February 2023 R/V Roger Revelle cruise RR2301 (Chief Scientist: Tamara Russell). Survey lines were acquired at a typical vessel speed of ~9 kt (~4.6 m/s), with tracks spaced ~12 km to provide almost 100% bathymetric coverage. Adverse sea conditions during data acquisition caused a considerable number of ping artifacts due to vessel motion, which were removed manually on shore using QPS Qimera software. The final bathymetric and acoustic backscatter amplitude grids were constructed using MB-System software at 100 m x 100 m node spacing. The grids are in GMT-compatible netCDF format and are named as "ZTopo" for the bathymetry grid and "ZAmpC" for the acoustic backscatter grid. The survey was supported by the University of California Ship Funds program. DOI: 10.60521/331612

Gas hydrate assessment from well logs in the North Carnarvon Basin, offshore Western Australia
- Author(s): Naim, Fawz; Cook, Ann
- Description: The data set consists of a gas hydrate assessment using 120 petroleum industry wells in the North Carnarvon Basin, offshore Western Australia. Well data was downloaded from the Geoscience Australia database. The gas hydrate stability zone (HSZ) was identified for each well, based on bottom water temperature, bottom hole temperature and hydrostatic pressure. The presence of hydrate is evaluated using resistivity and gamma ray well logs. Some wells had additional data such as P-wave velocity and bulk density which was used when available. A background resistivity was identified or calculated for each hole and resistivity increases above background (0.5 ohm-m and above) were used to identify potential gas hydrate accumulations. The highest resistivities above background were categorized as "A" accumulations, and the lowest were categorized as "D", following the categorization of Majumdar et al., 2017 (Marine and Petroleum Geology). The data file is in Excel spreadsheet format, with column headers. The data set was generated as part the project called, Carbon storage in widespread low-saturation gas hydrate systems. Funding was provided from NSF CAREER award OCE17-52882. DOI: 10.60521/331592

CDP navigation for processed multi-channel seismic reflection data from the U.S. Mid-Atlantic margin (EN555, 2015)
- Author(s): Ruppel, Carolyn; Kluesner, Jared; Edwards, Joel; Danforth, William; Miller, Nathan; Worley, Charles; Bergeron, Emile; O'Brien, Thomas; Nichols, Alexander
- Description: This data set is the Common Depth Point (CDP) navigation files for 30 processed high-resolution multichannel seismic reflection lines acquired by the U.S. Geological Survey Woods Hole Coastal and Marine Science Center in 2015 on R/V Endeavor, cruise EN555, with a towed sparker source. The data were collected on lines oriented mostly down the continental slope from 100 to 2000 meters water depth or parallel to the continental shelf. The source was the USGS Woods Hole Applied Acoustics Delta Sparker attached to a surface-towed sled. The source was operated at 2.4 kJ and usually fired at 5 s intervals. Seismic reflections were recorded using the 72-channel Geometrics GeoEel liquid filled streamer (nine 50-m-long active sections; total length 555 m) with group spacing of 6.25 m and depth control using birds. For seismic navigation, the USGS used its own GPS equipment (Hemisphere antenna) mounted on the 01 deck. Positions were recorded using UTM zone 18N and the WGS84 datum. There was no GPS tail buoy on the streamer. Individual seismic shot data (SEG-D data and GPS coordinates) were recorded with Geometrics acquisition seismic software with 0.5 ms sampling and record length of 4.5 s. SEG-Y files sorted to CDP gathers were imported to the Seismic Unix seismic processing software, where various processing steps were completed. Using Matlab, the CDP coordinates were smoothed with a Savitsky-Golay filter over 7 points in the x-coordinate and 9 points in the y-coordinate. These data files are in ASCII format and include a header. In these files, CDP positions are reported both in arcseconds (UTM18) and converted to geographic coordinates. CDP positions have estimated uncertainty of 20 m along the line and 30 m perpendicular to the line. Detailed acquisition and processing parameters are described in the associated documents. Funding was provided to the USGS Gas Hydrates Project through DOE NETL interagency agreements DE-FE000291 and DE-FE0005806. DOI: 10.60521/331586

- Author(s): Krauss, Zoe; Wilcock, William
- Description: This microseismicity catalog is derived from a single ocean-bottom seismometer on the Endeavour Segment of the Juan de Fuca ridge (network code NV, station code KEMF). The seismometer was installed on the Ocean Networks Canada NEPTUNE cabled observatory. Earthquake origin times, ranges (hypocentral distance between earthquake and seismometer), moments, and moment magnitudes are provided for earthquakes between 26 September 2011 and 31 May 2017. The data file is in ASCII format. The first row is a column header that describes the content of the catalog: origin time of the earthquake in unix format ('time'), the range to earthquake in km ('eventRange(km)'), the earthquake moment in dyne-cm ('eventMoment(dyne-cm)'), and the earthquake moment magnitude. Each line of the file corresponds to one earthquake. Not all earthquakes have an estimated moment due to selection criteria. Earthquakes occurring between June 2012 and June 2013 are excluded due to instrumental noise. Details of the methods used to create this catalog may be found in the Krauss, Z., Wilcock, W.S., & Baillard, C. paper, "A single-station earthquake catalog for the Endeavour segment of the Juan de Fuca ridge (2011-2016): challenges and implications for the spreading cycle". The data set was generated as part of the project titled "Microearthquakes on the Endeavour Segment, Juan de Fuca Ridge: A Near Real Time Earthquake Catalog for the ONC Cabled Observatory and a Reanalysis of Historical Data". Funding was provided by NSF grant OCE-1833419. DOI: 10.60521/331527

Seafloor photos of sediment grab locations, western Long Island Sound (2023)
- Author(s): Nitsche, Frank, O; Kenna, Timothy; McHugh, Cecilia; Conroy, Chris
- Description: Sediment samples were obtained with a Ponar grab sampler during R/V Lowell Weicker surveys of western Long Island Sound in June 2023. The sampling was done as part of the Long Island Sound mapping project Phase 3A. Two GoPro video cameras mounted to the frame of the Ponar sediment grab device were used to capture video of the seafloor to help characterise its nature at the location of the grab samples. One video camera looked forward, the second looked straight down. Diving lights were used to illuminate the bottom. At some stations one of the two camera failed to record a suitable video due to battery or other problems. Also, the three stations on the first day were recorded only with the bottom-looking camera. These still images are in JPEG format and were extracted by Chris Conroy as frame grabs from the video when the seafloor was showing the clearest. For geographical location, the images where tagged with the location recorded for the sediment grab station which is based on the ship DGPS system. The bottom images were collected to provide a better overview of the actual seafloor from which the grab samples are taken. They also allow the seafloor character to be classified when a grab sample could not be recovered, e.g. when the bottom was too hard or consisted of exposed rocks. This project was made possible by the Long Island Sound Research and Restoration Fund, established by a Memorandum of Understanding among the members of the Policy Committee of the Long Island Sound Management Conference and administered by Long Island Sound Cable Fund Steering Committee.

Raw high-resolution multi-channel seismic reflection (MCS) field data from the JS2203 Gulf of Mexico Campeche Bank Seismic Survey (2022)
- Author(s): Lowery, Christopher; Perez-Cruz, Ligia; Urrutia-Fucugauch, Jaime; Wei, Jingxuan; Austin, James; Standring, Patricia
- Description: This data set consists of raw multi-channel seismic reflection (MCS) data in SEG-Y format, collected in July 2022 along the continental slope of the Campeche Bank aboard R/V Justo Sierra. The research objective was to map the detailed stratigraphy of sediment drift deposits to explore the history of the Loop Current and its climatic implications. We used the portable high-resolution seismic acquisition system operated by Scripps Institution of Oceanography, which comprised a source array of two 45 cubic inches G.I. air-guns and a GeoEel streamer with 120 channels at a spacing of 6.25 m. The air-gun array was fired every 12.5 m and was towed at a depth of 3 m. Data was recorded using the Geometrics seismic recording system with sample rate of 0.5 ms and recording length of 4 ms. A 50-ms delay was created during each shot as a buffer between the timing pulse that starts the recording and the trigger pulse that fires the air-guns. A total of 11 seismic lines were acquired including two long strike lines, five dip lines, two tilted dip lines and two short transition lines. The shot spacing was not exactly 12.5 m during the first three lines (1001-1003) due to system glitches, therefore, it is necessary to merge navigation with SEG-Y headers to ensure accurate processing of these lines. Detailed acquisition parameters and cruise incidents are described in the associated documents.

- Description: This data set consists of raw high-resolution multi-channel seismic reflection (MCS) field data collected in 2021 over the Vitoria Trindade Ridge and Columbia Channel during research cruise CORE-VTRCC on naval vessel Nho Cruzeiro do Sul. The MCS data was acquired using a sparker seismic source with 800 tips model Geo-Source 800, up to 7 kJ energy power supply (GeoSpark 2000X) and a 48-channel streamer, all from the Geo Marine Survey Systems. Seismic acquisition and SEG-Y conversion was performed with the GeoRecorder software, also from Geo Marine Survey Systems. The Geo-Source 800 used a negative discharge for seismic pulse generation which results in a more stable seismic signature with a frequency range between 200 – 3000 Hz, centered at ~1 kHz. The streamer was composed of three hydrophones per channel, with a total active length of 150 m and 2 x 25 m cable stretches, to make a total of 200 m of streamer deployment. Channel distance in the streamer is 3.125 m and channel sampling occurred at 10 kHz. Geographic geometry was supplied by a DGPS antenna placed atop the seismic source configured with the WGS-84 ellipsoid and UTM projection zone 23S. Geometry distance averaged 5 m between source and streamer (dx) and ~20 m between source and first channel (dy). The source was placed at 1.5 m water depth and the streamer was at 0.5 m water depth. Energy levels and trigger interval for pulse generation varied across the survey depending on the bathymetric profile. Vessel velocity during seismic acquisition averaged 4 knots. See additional information in the associated Methodology report. These raw field MCS files are in SEG-Y format. Funding for this work was provided through FAPESP awards 2016/24946-9 and 2020/08847-6, and through the Brazilian Navy program PROAMAZONIA AZUL. DOI: 10.26022/IEDA/331494

- Description: This data set consists of sub-bottom profiler data collected in 2021 over the Vitoria Trindade Ridge and Columbia Channel during research cruise CORE-VTRCC on naval vessel Nho Cruzeiro do Sul. The high-resolution sub-bottom data was acquired with a hull-mounted Kongsberg SBP-120 CHIRP system. Survey geometry came from a SeaPath 330 positioning system with two GNSS antennas without differential positioning. Acquisition occurred in the Kongsberg SIS software with the ellipsoid WGS-84 and a UTM projection and zone 23S. The equipment was operated with one main channel, in a frequency of 2.5-6.5 kHz, with chirp up linear pulse, which results in a maximum vertical resolution ~0.3 ms. The data was logged in Topas raw format and converted to SEG-Y format. The power of the SBP pulse and trigger interval varied along the survey depending on ocean conditions and seafloor depth. Seismic data was then converted from time to depth assuming a sound speed of 1500 m/s. Ship survey speeds ranged from 4-7 knots. The files are in SEG-Y format. Funding for this work was provided through FAPESP awards 2016/24946-9 and 2020/08847-6, and through the Brazilian Navy program PROAMAZONIA AZUL. DOI: 10.26022/IEDA/331484

- Description: This data set presents photographs of sediment samples collected in 2021 over the Vitoria Trindade Ridge during research cruise CORE-VTRCC on naval vessel Nho Cruzeiro do Sul. During the sampling program, nine seafloor sediment samples were collected within the Vitória-Trindade Ridge with a Van-Veen grab sampler (3600 cm²) on the top of the volcanic seamounts. Sample V7 collected only rhodoliths, without additional sediments. Samples were washed, dried, weighed, sieved, and analysed. Microscopic photographs were taken with a Zeiss Stemi DV4 stereomicroscope, at zoom scale of 8x and a total diameter of 26 mm. The photographs are in JPEG image format. For the analysis, each seafloor sample was subdivided into ten subsamples (Q number). Codes: V# - Number of Sample (_# goes when there is multiple images for the same sample); Q# - Number of the quartile sample (only for the biofacies). Funding for this work was provided through FAPESP awards 2016/24946-9 and 2020/08847-6, and through the Brazilian Navy program PROAMAZONIA AZUL. DOI: 10.26022/IEDA/331483

- Description: This data set presents sediment sample data consisting of biofacies abundance and sediment grain size and properties for samples collected in 2021 over the Vitoria Trindade Ridge during research cruise CORE-VTRCC on naval vessel Nho Cruzeiro do Sul. During the sampling program, nine seafloor sediment samples were collected within the Vitória-Trindade Ridge with a Van-Veen grab sampler (3600 cm²) on the top of the volcanic seamounts. Sample V7 collected only rhodoliths, without additional sediments. Grain sizes larger than 40 mm diameter (pebble size) were separated for rhodolith measurements. Sediment samples were washed to dissolve the salt concentration for 48 hours, then oven-dried at 45 °C for 72 hours. The rhodolith samples were dried at 35 °C for 48 hours. The morphometry of the rhodoliths was classified in spheirodal, discoidal and ellipsoidal based on the measurement of the long (L), intermediate (I) and short (S) axis with a Vernier Caliper. Samples were weighed and sieved in phi fractions (-1.5, -1.0, -0.5, 0, 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0 and > 4.0) for 10 minutes. Samples sieved were described in phi fractions and were grouped in the following orders: granules (-2 to -1), very coarse sand (-1 to 0), coarse sand (0 to 1), medium sand (1 to 2), fine sand (2 to 3), very fine sand (3 to 4) and silt (> 4). The mean grain size and sorting were analyzed on Gradistat v9.1 software. Sediment samples were also placed on a Petri dish for microscope analysis and photography using Fiji software. Grains were then classified (Carbonate debris, foraminifers, bryozoans, sponge spicules, bivalves, gastropods, crustaceans, echinoderms, and annelida) and abundance was quantified based on 300 random point counts per sample. The data file is in Excel spreadsheet format. In the file names, SS = "Seafloor Samples". For the analysis, each seafloor sample was subdivided into ten subsamples (Q number). Codes: V# - Number of Sample (_# goes when there is multiple images for the same sample); Q# - Number of the quartile sample (only for the biofacies).

- Description: This data set consists of sound velocity data collected in 2021 over the Vitoria Trindade Ridge and Columbia Channel during research cruise CORE-VTRCC on naval vessel Nho Cruzeiro do Sul. To estimate sound velocity profiles for bathymetric processing, temperature profiles were first obtained for the water column throughout the survey every 50 nautical miles, for a total of 31 profiles. For that we used Expendable Bathythermograph (XBT) Lockheed Martin model T5 for the deeper portion of the survey (down to 1860 m water depth) and the model T7 over the shallower regions (down to 760 m). A salinity profile was then calculated by linearly interpolating the measured temperature profile to the nearest WOA/RTOFS salinity profile. Sound speed values were then calculated from the salinity updated profile using the UNESCO equation. The data file is in ASCII format.

- Description: This processed swath bathymetry data set was collected in 2021 over the Vitoria Trindade Ridge and Columbia Channel during research cruise CORE-VTRCC on naval vessel Nho Cruzeiro do Sul. The data files are in MB-System-compatible GSF format (mbio format 121) and contain processed swath bathymetry and acoustic backscatter data. The multibeam bathymetry was collected with the Kongsberg EM-122 deep echo-sounder operating at a frequency of 12 kHz. The system was coupled with the SeaPath 330 positioning system with two GNSS antennas. Acquisition occurred in the Kongsberg SIS software with the ellipsoid WGS-84 and UTM projection. Swath width was to set to be up to 55° with a ping frequency of 40 Hz. Due to the deep characteristics of the EM-122 equipment, multibeam bathymetry was not performed in water depths shallow than 200 m. To estimate sound velocity profiles for bathymetric processing, temperature profiles were first obtained for the water column throughout the survey every 50 nautical miles, for a total of 31 profiles. For that we used Expendable Bathythermograph (XBT) Lockheed Martin model T5 to the deeper portion of the survey (down to 1860 m water depth) and the model T7 over the shallower regions (down to 760 m). A salinity profile was then calculated by linearly interpolating the measured temperature profile to the nearest WOA/RTOFS salinity profile. Sound speed values were then calculated from the salinity updated profile using the UNESCO equation. Sound velocities were then incorporated during the multibeam bathymetry acquisition directly into the SIS software.Multibeam bathymetry preprocessing was performed using the CARIS HIPS software from Teledyne during the cruise. A Patch Test calibration of the echo-sounder was done atop the Columbia Seamount on October 26th on where roll, pitch, yaw, heading and the time delay were calibrated. The corrected values from the Patch Test were then inserted on the processing procedure. Survey velocity range between 4-7 knots. Finally, spike removal and surface equalization processing were performed with the software EIVA NaviModel Producer after the survey.

- Description: This data set consists of processed magnetic data collected in 2021 over the Vitoria Trindade Ridge and Columbia Channel during research cruise CORE-VTRCC on naval vessel Nho Cruzeiro do Sul. A SeaSPY magnetometer from Marine Magnetics was used to acquire the magnetic field data. The sensor (torpedo) was towed 250 meters from the vessel and 300 meters from the vessel GPS antenna, and was towed about 30 to 35 meters below the sea level. The SeaSPY magnetometer is a Proton Precession (Overhauser) sensor of absolute accuracy, and the resolution of the system is 0.1 nT and 0.001 nT, respectively. The data was acquired in a 10 Hz frequency, from the continental slope to the furthest point from the continent, nearby the Trindade Island. The frequency resulted in measurements for every meter traveled, on average, considering the variable ship speed between four and seven knots. The survey also occurred in parallel to the seismic survey, without any perceptible interference. The data file is in ASCII format with header lines.

Processed pre-stack depth-migrated seismic reflection data from the Juan de Fuca Ridge to Trench multi-channel seismic survey (MGL1211)
- Author(s): Carbotte, Suzanne; Han, Shuoshuo; Canales, JuanPablo; Boston, Brian
- Description: This data set presents processed Multi-Channel Seismic (MCS) reflection data acquired during the Juan de Fuca (JdF) Ridge-to-Trench experiment conducted in 2012. In this experiment two ridge-to-trench transects across the Juan de Fuca plate, from Endeavour Ridge to offshore Washington state and from Axial Volcano to offshore Oregon state, and one 400 km-long trench-parallel transect extending from 44.3N to 47.8N were acquired during the 2012 R/V Langseth survey MGL1211. The seismic reflection images of the two ridge-to-trench transects reveal the sediment stratigraphy and crustal structure across the JdF plate and just seaward of the Cascadia deformation front. The files in this data set are pre-stack depth-migrated reflection stacks with advanced processing routines applied and were processed along with the CASIE21 data set. Details of the processing work flow are described in the linked data processing document. The data files are in SEG-Y format. Funding for original data acquisition was provided through NSF grants OCE 1029411 and 1029305. Results from this study are described in Carbotte et al., Science Advances, 2024. DOI: 10.60521/331457

- Description: Along the Polish coast of the Baltic Sea, Puck Lagoon provides the most valuable benthic habitats. Despite this, the area previously lacked high-resolution bathymetry and backscatter data sets which are essential for enhancing our understanding of this biodiverse area. To address the lack of data, a new project called "The pioneering exploration of the Puck Lagoon based on high-resolution airborne and acoustic remote sensing" set out to collect the first comprehensive set of marine and aerial measurements of the seafloor covering the entire lagoon. The project is part of the National Science Centre SONATINA 5 research programme. This data set presents a range of bathymetry and remote sensing data generated as part of the project. There are seven GeoTIFF grids and one GeoTIFF image. The GeoTIFF grids are referenced in PL-EVRF2007-NH vertical system and UTM-34N projected coordinate system based on the ETRS89 ellipsoid. The majority of the files are named from the measuring source used for acquisition, as follows. The MBES_DEM and MBES_BSS grids represent digital elevation model (bathymetry) and backscatter of the acoustic signal acquired with Teledyne Reson T50/T20 multibeam echo-sounders. The LIDAR_DEM and LIDAR_INTENSITY grids represent the digital elevation model and intensity of the laser signal, respectively, from an airborne bathymetric LiDAR Riegl VQ-880-GII instrument. The PHOTO_DEM grid provides a digital elevation model derived after treating airborne photographs with Structure from Motion (SfM) techniques and then using the DepthLearn algorithm to correct for water refraction. The photographs were acquired with two PhaseOne iXM-100 airborne photogrammetry cameras. The ORTHOPHOTO GeoTIFF image represents an ortho-rectified image of the research area. The INTEGRATED_DEM grid was generated artificially by unification of digital elevation models from the multibeam echo-sounders and bathymetric LiDAR. The SDB grid shows Satellite-Derived Bathymetry (SBD) for the research area generated from SPOT-6 satellite imagery. All grids and the ortho-rectified image have a pixel size resolution of 0.2 m except for the SDB grid that has coarser cell resolution, approximately 5x8 m. Spatially, the study site covers an area of approximately 103 km2 but, depending on the method used, the coverage of each data type is different. This research was funded by grant number 2021/40/C/ST10/00240 from the National Science Centre, Poland. The contribution of Dr. Panagiotis Agrafiotis is part of the MagicBathy project funded by the European Union HORIZON research and innovation programme under Marie Sklodowska-Curie grant agreement number 101063294.

Digitised seabed and basement reflections from high-resolution Deep Tow sediment profiler records (1972 Galapagos Spreading Centre cruise South Tow leg 6, SOTW06WT)
- Author(s): Mitchell, Neil
- Description: In an R/V Thomas Washington survey in 1972, South Tow, leg 6 - SOTW06WT, the Scripps Deep Tow vehicle was deployed over the Galapagos Spreading Centre, covering an area 24 X 50 km including the ridge crest. The vehicle was towed close to the seabed at an altitude of only 130 m on average so that the paper records from the Deep Tow 4 kHz sediment profiler have good vertical resolution. The seabed and basement topography are useful for revealing fault escarpments. Also, if deposition of pelagic sediments is not significantly moderated by bottom currents or other mechanisms, their thickness can potentially be useful to date the underlying basement. Such may be true of the Galapagos Spreading Centre in the Panama Basin which lies close to the equatorial high pelagic productivity belt. Cores show the sediment to be a siliceous-calcareous ooze. The seabed and basement reflections were digitised from A4-sized paper copies of the 4 kHz reflection data, each corresponding to roughly a half-hour duration of the survey. The digitised values were interpolated in survey time to provide coincident values (i.e., two-way seismic time to both reflections at fixed survey time intervals). Two-way times were converted to depths using seismic velocities of 1500 and 1553 m/s for seawater and sediments, respectively. Those interpolated depth values were then merged with navigation (see associated Deep Tow vehicle navigation data set under the "Related Data" links on the right and under the "Related Data Sets" tab on the left) to provide profiles of seabed and basement elevations as well as sediment thickness. Depths to the basement and seabed for each file (corresponding to each A4-sized paper copy) were offset vertically so that the seabed depth coincided in a least-squares sense with the bathymetry column in the associated navigation files. Hence, basement and seabed depths are relative to the ocean surface. These files are in ASCII format and include a header line. DOI: 10.26022/IEDA/331451
SOTW06WT Deep Tow vehicle navigation, South Tow leg 6 (1972)
- Author(s): Mitchell, Neil
- Description: This data set consists of Deep Tow vehicle navigation files for Galapagos Spreading Centre 1972 cruise SOTW06WT. These ASCII navigation files were generated by Neil Mitchell at the University of Manchester as follows. According to Klitgord & Mudie (1974), a network of six bottom transponders was originally deployed for the survey. Acoustic ranging between them, the Deep Tow vehicle and the ship enabled their relative positions to be calculated for most of the survey duration, with an internal accuracy of ~40 m. For the remaining one-third of the survey, it is unclear how the vehicle position was calculated although a cable trajectory model is mentioned in Klitgord and Mudie (1974) for a line over the northerly flank, which may have been used more widely. In addition, satellite fixes of the vessel allowed the survey to be placed in a geographic framework with an accuracy of ~0.5 km (after digitising accuracy is included, position accuracy will be somewhat poorer than this). A vehicle track map originally produced by Bob Detrick was digitised to generate (x, y, survey time) and these values were merged with digital data files obtained from the Marine Physical Laboratory at Scripps Institution of Oceanography to produce (x, y, Deep Tow vehicle depth, bathymetry at the Deep Tow position, survey time). The navigation files presented here contain these positional values updated with geographical coordinates that were obtained from longitude = X * 7.963700000000E-06 - 86.179455500; latitude = Y * 8.728372093023E-06 + 0.56179069767, where X and Y are the local coordinates in meters. That is, a flat-Earth approximation is used and is justified given the small geographical area and the age of the data (position uncertainty is larger than projection error). The X and Y values are also in the files. DOI: 10.26022/IEDA/331450

Heat flow data from the Hikurangi subduction zone, 2019 (RR1901, RR1902)
- Author(s): Harris, Robert; Torres, Marta; Solomon, Evan
- Description: This heat flow data set was acquired during R/V Roger Revelle cruises RR1901 and RR1902 conducted in 2019 as part of the project called SAFFRONZ: Slow-Slip and Fluid Flow Response Offshore New Zealand - Probing the Nature of the Hikurangi Margin Hydrogeochemical System. Fluid generation, migration, and pore pressure at subduction zones are hypothesized to exert a primary control on the generation of seismicity, low-frequency earthquakes and slow slip events (SSEs). The Hikurangi margin (east coast of North Island, New Zealand) exhibits dramatic changes in the along-strike depth distribution of SSEs, depth of interseismic coupling, inferred pore pressure, and other subduction-related parameters. In 2019, in-situ measurements of thermal gradient and thermal conductivity were collected using the Oregon State University 3.5-m violin-style multi-penetration heat flow probe. In most cases seeps were targeted to document advective heat flow, if any. The thermistor string houses 11 thermistors and measures both the in-situ thermal gradient and thermal conductivity that are combined to determine the heat flow. On most measurements the probe position was determined with ultra-short baseline telemetry (USBL). The data was processed using SlugHeat (https://marine-heatflow.ceoas.oregonstate.edu/software/). The data file is in Excel spreadsheet format, with column headers. Funding was provided by NSF grants OCE17-53665 and OCE17-53617. DOI: 10.26022/IEDA/331405

Gridded seismically-derived thicknesses of Plio-Pleistocene sediments and depths to the top of the Miocene S-reflection in the Red Sea
- Author(s): Mitchell, Neil; Ligi, Marco
- Description: The top of the Miocene evaporites throughout most of the Red Sea is marked by a prominent reflection in seismic data, called the "S-reflector" in the literature. The topography of this reflection can potentially reveal how the Miocene evaporites have moved since they were deposited. The thicknesses of the Plio-Pleistocene sediments above the evaporites may also reveal how subsided areas of the Miocene evaporites have been filled with sediment, as well as effects of sediment transport within the basin and sediment supply. The S-reflector is imaged in seismic data, including in early single-channel seismic data from the 1960s. This data set presents grids of seismically-derived thicknesses of Plio-Pleistocene sediments and depths to the top of the Miocene S-reflection in the Red Sea. Six grids are provided here. All are in GMT COARDS-compliant netCDF format and are in geographic coordinates. Four of these grids cover a large area and have file names starting with "redsea_Depth_S_reflection" or with "redsea_PlioPleistoceneThickness". The remaining two grids are derived from 3-D multi-channel seismic data and have names beginning "3DSeismicPP" where PP stands for Plio-Pleistocene. The four large-area grids were produced as follows. The seismic two-way times to the seabed and S-reflection were digitised from data of varying quality from 17 research cruises and from one commercial 3-D seismic survey. The quality of the seismic data varied, including line-drawing interpretations, paper records, and modern digital records. Two-way times were converted to depths below sea-level using 1538 m/s and 1900 m/s for the water column and Plio-Pleistocene sediments, respectively. Navigational accuracy reflects the positional technology in use during the surveys and varied from transit satellites in the 1960s to 1970s to GPS from the late 1980s onwards (details are available in the headers of the track line data for these earlier cruises from ncei.noaa.gov). Nevertheless, the accuracy even for the earliest cruises was considered adequate due to the coarse nature of the mapping done in this study. Each cruise file of the results (S-reflection depth and Plio-Pleistocene thickness) was first binned within cells of 0.01° X 0.01° to ensure relatively uniform along-track data density. Those cruise files were subsequently combined and binned again with a cell size of 0.1° X 0.1°. Grids were then generated using the GMT program "surface" with a tension factor of 0.35. In the "interpolated" grids, grid nodes that were more than 0.15° geographical degrees (~16 km) from measurements (of S-reflection depth or sediment thickness) were masked out (i.e., set to NaN). The "not_interpolated" grids were similarly constructed, though with grid nodes more than 0.015° (~1.6 km) from measurements masked out. Hence, these are like the interpolated grids but give a better sense of where the measurements were made, at the expense of being less useful for visualising variations. Finally, any areas of data overlapping with geomorphology that in multibeam sonar data was interpreted as volcanic (e.g., cones, ridges) were masked out (set to NaN). Further details are given in the associated references. The remaining two grids derived from 3-D seismic data give more detail of S-reflection depth and thickness of the Plio-Pleistocene sediments. These two grids were derived from commercial 3-D multi-channel seismic reflection data originally collected for BG in 1999. There is little information on the original processing of the commercial seismic data, although it extended to time migration. The 3-D volume comprises 4879 crosslines (SW-NE) spaced 12.5 m apart and 1729 in-lines (SE-NW) spaced 25 m apart. The seismic data have good quality above the Miocene evaporites and the S-reflection is clear throughout the volume. The seabed and S-reflections were mapped out using the geological interpretation software IHS Kingdom. For consistency with the large-scale grids, the same velocities of 1538 m/s and 1900 m/s for water column and sediments have been used to compute S-reflection depths and Plio-Pleistocene sediment thicknesses. More details are given in the associated references. DOI: 10.26022/IEDA/331395

Residual mantle Bouguer anomaly (RMBA) grid, 42-50 Ma NE Pacific between Molokai and Murray FZ
- Author(s): Blackman, Donna; Laske, Gabrielle
- Description: Residual mantle Bouguer anomaly grid calculated for the Ohana project located 25-30.5°N, 145.5-137.5°W in the NE Pacific. This ~500x600 km area was the site of an Ocean Bottom Seismometer array deployed Nov 2021-Feb 2023 by a team led by Gabi Laske. Donna Blackman led the bathymetric and gravity analyses. Gravity data processing started with the satellite-based Free Air Anomaly grid (grav_32.1.nc, Sandwell et al., 2014). The contributions of seafloor topography (from the corresponding bathymetry grid called Ohana_bathymetry_200m_v5n.grd), and of a constant thickness (6 km) crust were removed assuming 1700, 250, and 350 kg/m3 density contrasts at the seafloor, upper/lower crust (1.5 km depth), and basal interfaces, respectively. The best-fit exponential age trend of the predicted mantle Bouguer anomaly was removed as an estimate of the contribution of plate cooling for this 40-52 Ma area. The resultant RMBA data was gridded at 200 m. The RMBA data file is in GMT-compatible netCDF grid format. DOI: 10.26022/IEDA/331358

Southwest Indian Ridge (SWIR 9-16E) residual mantle Bouguer gravity anomaly data (netCDF format)
- Author(s): Lin, Jian; Dick, Henry
- Description: Shipboard free-air gravity data were processed in the same way as described by Wang et al. (2015) to obtain Residual Mantle Bouguer Anomaly (RMBA): The gravitational effects of seafloor topography and relief on the crust-mantle interface were subtracted from the free-air gravity anomaly to obtain mantle Bouguer anomaly (MBA), assuming a reference crustal thickness of 6 km and using the spectrum method of Parker (1973). Densities of water, crust, and mantle were assumed to be 1.03 10^3, 2.7 10^3, and 3.3 10^3 kg m^-3, respectively. RMBA was then calculated by removing the gravitational effect of lithospheric cooling from MBA, based on a 3-D mantle thermal model. The mantle thermal structure was calculated for a 100 km thick layer, using the 2-D age grid of Wang et al. (2015) and assuming simple 1-D plate cooling (Turcotte and Schubert, 2002; Wang et al., 2011). The parameters used in the calculation are the same as in Wang et al. (2011). This mantle thermal model was then converted to a 3-D mantle density structure, which was used to calculate gravitational effects. The data file is in GMT-compatible netCDF grid format.

Processed single-channel seismic profiles acquired in 2001 along the Lake Malawi (Nyasa) Rift
- Author(s): Scholz, Christopher
- Description: There are 25 Single-Channel Seismic Lines that are confined to the North, Central, and South Basins of the Lake Malawi Rift. These were collected in 2001 as part of the Lake Malawi Sub-Lacustrine Fan Study with support from Syracuse University industrial associates. All files are in SEG-Y format, with coordinate reference system and navigation information in the headers. Record length is three seconds two-way travel time, 0.5 ms sample rate. Profiles are generally oriented north-south (strike), or east-west (dip). Data were acquired aboard R/V Ndunduma, an 18-meter-long vessel of opportunity operated by the Malawi Department of Fisheries. Chief Scientist was Christopher A. Scholz. Line spacing is variable. Source was a 10 in3 and 20 in3 Bolt 600B airgun — 2000 psi. Receiver was a S.I.G. 10 m 16 hydrophone element streamer. Acquisition was via a Elics-Delph 2 at a 0.5 ms sample rate. Navigational data was acquired with Continuous Autonomous GPS. Data bandwidth is 50-450 Hz. General processing at Syracuse University was performed using Promax software with the following workflow: 3–trace horizontal stack, band-pass filter (80–500 Hz), 100 ms AGC, trace balancing.

Processed PROBE multi-channel seismic dip and strike profiles acquired in 1986-1987 along the Lake Malawi (Nyasa) Rift
- Author(s): Scholz, Christopher; Rosendahl, Bruce
- Description: There are 28 Multi-Channel Seismic lines, collected in 1986/87 across the Central and South Basins of the Lake Malawi Rift as part of the PROBE project (Proto-Rifts and Oceanic Basin Evolution) of Duke University. All files are in SEG-Y format, with coordinate reference system and navigation information in the headers. The projection is UTM-36S. The record length is 6 seconds two-way travel time, 4 ms sample rate. Profiles are generally oriented east-west across multiple rift segments. Data were acquired aboard R/V Nyanja, a 36-foot-long dedicated geophysical vessel transportable by cargo aircraft. Source was a single 140 cubic inch EERI airgun, or 3x40 cubic inch array of GSI sleeve guns. Streamer was a GECO custom-built 960 m active-length cable comprising 48 groups (20 m group interval); lead-in cable length varied from 250-440 m. Streamer depth was nominally 10 m and controlled a buoy suspension system. Fold coverage was nominally 24-fold. Acquisition was via Texas Instruments DFS-V, at 2 ms sample rate. Navigation was by transit satellite, radar, automatic speed log and deduced reckoning. Navigational accuracy ranges from <100 m to several km in places. Every line is controlled by a minimum of two fixes and a 40-80 km line is controlled by 5-8 good fixes. Chief Scientist was Bruce R. Rosendahl. Data were recovered from 9-track tape and archived on modern media under the supervision of Christopher A. Scholz, Syracuse University. Legacy time processing at Duke University was completed with Digicon DISCO 50 software on a DEC VAX 11/750 computer, applying the following workflow: Demultiplexing, Resample, Geometry Definition, Trace Edit, Sort, Deconvolution, Filter, Velocity Analysis, Stacking, Mute, Migration, Display. Deconvolution is a predictive gap deconvolution, occasionally spiking deconvolution is used. Filtering was variable, typically a bandpass filter with a Hanning taper was employed with typical cutoffs of 6-10 Hz at the low end, and 50-55 Hz at the upper end. Some lines received time-variant filtering and occasionally notch filters were used. Select lines were subjected to a post-stack finite difference time migration routine. Funding for data collection and processing was from multiple 1980s-era oil and gas companies. DOI: 10.26022/IEDA/331340

- Author(s): Marjanovic, Milena
- Description: The data set consists of a 3-D full-waveform inversion (FWI) model of compressional velocities within the upper crust beneath the East Pacific Rise 9º50'N. The velocity model was obtained using 3-D multi-channel seismic data collected in 2008 during the MGL0812 experiment aboard R/V Marcus G. Langseth (PIs: John Mutter, Suzanne Carbotte). We use ~90 000 shot gathers; Only mid-to-far source-receiver offsets (2-6 km) are included in the inversion. The final velocity model is obtained after 15 iterations using frequencies up to 7 Hz. The details on the inversion parameters and modeling are provided in Marjanović et al. (2018). The model is provided as an ASCII file. The size of the grid is 441 x 551 x 200 (x,y,z) grid points with the horizontal and vertical spacing 100 m and 25 m, respectively. The origin of the grids is Easting=562090; Northing=1045620; UTM Zone=13; Azimuth of the 3-D box =8º. This velocity model work was funded by Marie S. Curie Individual Fellowship (No: 655283 3DWISE).

Bathymetry data (GeoTIFF floating point grid format) from the Galapagos Platform area (AT50-09BC, 2023)
- Author(s): Fornari, Daniel; Robinson, Laura; Wanless, Dorsey; Taylor, Michelle; Hoy, Shannon
- Description: This data set presents EM124 shipboard multibeam data from various locations around and on the Galapagos Platform, collected during R/V Atlantis leg AT50-09BC in April 2023 that included 22 Alvin HOV dives. The multibeam data were acquired to fill in areas where previous mapping around the Platform, carried out in 2000, 2001 and 2010, was incomplete, and to serve as base maps to plan and execute Alvin dives. The AT50-09BC expedition is a collaborative project between UK and USA scientists at U. Bristol, U. Essex, Boise State U. and Woods Hole Oceanographic Institution (WHOI). The objective of this multidisciplinary research is to investigate the shallow and deeper portions of the Galapagos Platform to better understand the geological evolution of this important volcanic archipelago and the biological and climate records contained in the fauna. The project is funded through research grants from the Natural Environment Research Council in the UK, and from the Ocean Sciences Division of the National Science Foundation in the USA.Bathymetric mapping was a major component of the activities of the expedition as accurate maps were essential in dive planning and in dive site selection (see site maps with each dive summary in the cruise report). The multibeam data collection, quality control, data processing, and ping editing were undertaken by many members of the science team as part of regular watch-standing shifts and was headed by Shannon Hoy from NOAA-Ocean Exploration, who led the production of final map products and the compiled dive maps. Both QPS Qimera and Fledermaus were used for multibeam processing, editing, and visualization. ArcGIS and Fledermaus were used for compiling map data and planning dive traverses. Areas mapped included the following totals: Costa Rica EEZ (during transit) = 5019 km2; Ecuadorian EEZ = 19,055 km2; Area mapped inside the Galapagos National Park = 16,796 km2. Total seafloor mapped = 24,074 km2 (approximately the size of Rwanda or New Hampshire). The data files are in GeoTIFF floating point grid format. DOI: 10.26022/IEDA/331316

Southwest Indian Ridge mantle Bouguer and residual mantle Bouguer gravity anomaly data (netCDF format) between 61°-67°E
- Author(s): Cannat, Mathilde
- Description: Off-axis geophysical surveys provide a 26-m.y.-long record of axial tectonic and magmatic processes over a 660-km-long and melt poor portion of the ultraslow Southwest Indian Ridge. The data reveal a new type of seafloor (the smooth seafloor) that forms at minimal ridge melt supply, with little or no axial volcanism. The gravity data were primarily collected during Marion Dufresne cruise 135 in 2003 (https://campagnes.flotteoceanographique.fr/campagnes/3200080/). Details of the processing of the gravity data are provided in the Supplement Material section of Cannat et al. (2006). The residual mantle Bouguer anomaly (RMBA) was calculated from free-air ship gravity data by first subtracting the effect of topography of a constant crustal thickness (3.4 km; the mean seismic crustal thickness determined near 66°E (Muller et al., 1999)), constant density (2700 kg/m3) crust, and then the effect of upper mantle cooling with age (using magnetic anomaly picks). The thermal correction model assumes a simple square root of age mantle cooling law (Parsons and Sclater, 1977). The thermal model was cut off 25 km off-axis, and a constant temperature gradient used in the intervening axial region. The data files are in GMT-compatible netCDF grid format. The "mba" grid is the mantle Bouguer anomaly data and the "rmba" grid is the residual mantle Bouguer anomaly grid. DOI: 10.26022/IEDA/331313
Mid-Atlantic Ridge South of Kane FZ (21.75N-23.8N) residual mantle Bouguer gravity anomaly data (netCDF format)
- Author(s): Cann, Joseph; Smith, Deborah; Escartin, Javier
- Description: RMBA anomalies were digitized from Maia and Gente (1998) and used by Cann et al. (2015) to interpret the tectonic evolution of 200 km of Mid-Atlantic Ridge over 10 million years and the interplay of volcanism and faulting. The gravity data were collected during two cruises, RC2511 (Detrick et al., 1984) and SEADMA I (Gente et al., 1995) and combined with available data sets from NOAA - National Centers for Environmental Information, and the 1991 SIGMA cruise (from the Banque de Bathymetrie et Geophysique Marine (SISMER) data bank, France). Processing of the data is described in Maia and Gente (1998). The MBA was computed assuming a constant crustal thickness model (Prince and Forsyth, 1988) using the method of Parker (1973). Crustal thickness was assumed to be 6 km. Densities of seawater, crust and mantle were considered constant (1030, 2700, and 3300 kg/m3, respectively). The thermal correction was computed using a passive flow model (Phipps Morgan and Forsyth, 1988) to obtain the RMBA. The data file is in GMT-compatible netCDF grid format. DOI: 10.26022/IEDA/331314
Residual mantle Bouguer gravity anomaly data (netCDF format) in a corridor across the Mid-Atlantic Ridge at 24°-27°N
- Author(s): Tucholke, Brian; Lin, Jian
- Description: Shipboard free-air gravity data from R/V Ewing Cruises EW9208 and EW9606 in the Mid-Atlantic Ridge corridor at 24°-27°N were processed as described by Wang et al. (2015) to the obtain Residual Mantle Bouguer Anomaly (RMBA): The gravitational effects of seafloor topography and relief on the crust-mantle interface were subtracted from the free-air gravity anomaly to obtain mantle Bouguer anomaly (MBA), assuming a reference crustal thickness of 6 km and using the spectrum method of Parker (1973). Densities of water, crust, and mantle were assumed to be 1.03 10^3, 2.7 10^3, and 3.3 10^3 kg m^-3, respectively. RMBA was then calculated by removing the gravitational effect of lithospheric cooling from MBA, based on a 3-D mantle thermal model. The mantle thermal structure was calculated for a 100 km thick layer, using the 2-D age grid of Wang et al. (2015) and assuming simple 1-D plate cooling (Turcotte and Schubert, 2002; Wang et al., 2011). The parameters used in the calculation are the same as in Wang et al. (2011). This mantle thermal model was then converted to a 3-D mantle density structure, which was used to calculate gravitational effects. Note that, within a narrow axial region that contains ridge-axis offsets, this 1-D plate cooling model differs slightly from the 3-D passive mantle upwelling model used in Tucholke et al. (1997), in which lateral heat transfer across ridge offsets was considered. Thus, the calculated thermal structure and resultant gravity corrections for the 3-D passive upwelling model are smoother across ridge offsets than those predicted by the 1-D plate cooling model. However, differences between the two models are only a few mGal and are limited to a narrow zone proportional to the size of ridge offsets. The file presented here is in GMT-compatible netCDF grid format. Additional gravity and other shipboard data in this region are available at https://doi.org/10.26025/z2z7-kd89.

Mid-Atlantic Ridge residual mantle Bouguer gravity anomaly data (netCDF format) between the Fifteen-Twenty and Marathon fracture zones, 13°-15°N
- Author(s): Smith, Deborah; Escartin, Javier; Fujiwara, Toshiya
- Description: Gravity data collected during KN182-03 were combined with the gravity data from Fujiwara et al. (2003) and processed as described by Smith et al (2008). The free-air gravity data were reduced to obtain the mantle Bouguer and the residual mantle Bouguer anomalies (MBA and RMBA, respectively) following standard procedures (Kuo and Forsyth, 1988; Prince and Forsyth, 1988). The effects of the water-crust and crust-mantle interfaces were subtracted from the free-air gravity anomaly along tracks to obtain MBA using the method of Parker (1973), and assuming a crustal thickness of 5 km. Densities of water, crust, and mantle were assumed to be 1030, 2750, and 3300 kg/m3, respectively (Escartin and Cannat, 1999). The gravity thermal effect due to spreading was calculated using a passive upwelling model and the ridge geometry (Phipps Morgan and Forsyth, 1988). The calculated thermal effect was removed from the MBA along tracks to obtain the RMBA, which was then gridded. The data were gridded for 13°-15°N and the grid covers the Mid-Atlantic Ridge between the Fifteen-Twenty and Marathon fracture zones. The file presented here is in GMT-compatible netCDF grid format.

- Author(s): Spinelli, Glenn; Harris, Robert; Trehu, Anne
- Description: In 2022, in-situ measurements of thermal gradient were collected with a 3.5-m violin-style heat flow probe at three sites on the Juan de Fuca plate: around Nubbin Knoll, Diebold Knoll, and the MARGIN site (a basement high, likely a seamount, buried by the Astoria Fan). The multi-penetration heat flow probe was loaned from the U.S. Marine Heat Flow Capability. The thermistor string houses 11 thermistors. The in-situ thermal gradient is combined with an assumed thermal conductivity versus depth trend to determine the heat flow. The data was processed using SlugHeat (https://marine-heatflow.ceoas.oregonstate.edu/software/). The data file is in ASCII tab-separated format, with column headers. Funding was provided by National Science Foundation awards OCE19-24331, OCE20-34872, and OCE20-34896. DOI: 10.26022/IEDA/331310

Raw high-resolution single- and dual-channel seismic field data from the 2006 MERC I Eilat-Aqaba survey
- Author(s): Tibor, Gideon; Makovsky, Yizhaq; Agnon, Amotz; Barnea-Cohen, Osnat
- Description: The first high-resolution seismic survey, MERC I, in the area offshore Eilat in the northern Gulf of Aqaba was conducted from 29 October to 16 November 2006 and included the acquisition of 261 seismic lines with a total length of 426 km. The survey was carried out in two phases: deep survey (water depths of 100–700 m) onboard the R/V Etziona and a shallow phase (water depths of less than 100 m) onboard a fishing vessel called Danny-Boy. The high-resolution geophysical survey used a GeoResources GeoSparker200 seismic source generated by electrical spark at energies of 300–1000 J and seismic frequencies of 200–3000 Hz. During the deep survey, the system used two hydrophone arrays (i.e. dual-channel), one towed parallel to the sparker, and the other offset about 50m attempting to receive more seismic energy across steep slopes. In the shallow survey only one hydrophone array (i.e. single-channel) was towed parallel to the sparker. The seismic acquisition parameters are described in the associated documents. Funding was provided through the U.S. Agency for International Development Middle East Regional Cooperation program (MERC) under contracts TA-MOU-05-M25-004 and TA-MOU-08-M29-036.

Processed gravity data (netCDF format) at the Cocos-Nazca spreading center from cruise SR1806 (2018)
- Author(s): Zheng, Tingting; Lin, Jian; Schouten, Hans; Smith, Deborah; Klein, Emily; Parnell-Turner, Ross
- Description: Mantle Bouguer anomaly (MBA) was calculated by removing the gravitational effects of the water-crust and crust-mantle interfaces from the Free-air anomaly (FAA), assuming water, crust, and mantle densities of 1.03 × 10^3, 2.7 × 10^3, and 3.3 × 10^3 kg m^-3, respectively, and using a 6-km thick reference crust. Residual Mantle Bouguer anomaly (RMBA) was calculated by subtracting age-dependent thermal model from the MBA. The end-member model of the crustal thickness model here was calculated by the downward continuation of the RMBA to a depth of 10 km by assuming that the RMBA is controlled only by variations in crustal thickness. Free-air anomaly (FAA) was generated by combining the shipboard FAA data from cruise SR1806 with global satellite FAA data from Sandwell et al. (2014). The lithosphere cooling effect (i.e., thermal model) is estimated by assuming a 1-D half space plate cooling model. The data files are in GMT-compatible netCDF grid format. All data were gridded at 1-arc-second node spacing. The gravity calculation region is from 105°W to 95°W and 1°S to 5°N, but we suggest using data within 104°W to 96°W and 0 to 4°N to avoid boundary effects. This data set has a Zenodo DOI: https://doi.org/10.5281/zenodo.7590816.

Heat flow data from the Pythia's Oasis methane seep site, 2019 (AT42-17)
- Author(s): Harris, Robert; Spinelli, Glenn
- Description: Pythia's Oasis is a methane seep site 60 nautical miles offshore the coast of Oregon. This site is different from other seep sites. It hosts a discrete orifice that has continually vented low-salinity, hydrocarbon-bearing fluids since 2015 and was still active as of August of 2022. The site was discovered in 2015 during a Regional Cabled Array (RCA) Operations and Maintenance Cruise using hull-mounted sonar on R/V Thompson to detect methane bubble plumes in the water column. In 2019, in-situ measurements of thermal gradient and thermal conductivity were collected using the OSU 3.5-m violin-style heat flow probe. The thermistor string houses 11 thermistors and measures both the in-situ thermal gradient and thermal conductivity that are combined to determine the heat flow. On most measurements the probe position was determined with ultra-short baseline telemetry (USBL). The data was processed using SlugHeat (https://marine-heatflow.ceoas.oregonstate.edu/software/). The data file is in Excel spreadsheet format, with column headers. Funding was provided by National Science Foundation award OCE19-02446. DOI: 10.26022/IEDA/331300

Reprocessed depth-migrated seismic profiles (SEG-Y format), 1982 Hawaiian Islands survey, cruise RC2308
- Author(s): Cilli, Phillip; Watts, Anthony; Boston, Brian; Shillington, Donna
- Description: The original seismic data was acquired during R/V Robert D. Conrad cruise RC2308 and R/V Kana Keoki cruise KK8213 to the Hawaiian Islands and vicinity in August/September 1982. Navigation on Conrad was by Loran-C and a Magnavox satellite navigation system. Reprocessing has been carried out using the original Conrad field data (except for Line 330 which was reprocessed using a stack) and includes de-noise, de-bubble, deconvolution and migration. Reprocessed data has been converted to depth using P-wave velocity data acquired during the two-ship Expanding Spread Profiles 1-11 and 'picks' of top oceanic crust and Moho used to constrain the long-term mechanical properties of Pacific Oceanic lithosphere. The files are in SEG-Y format. Funding for the study came from NSF and NERC. DOI: 10.26022/IEDA/331293

Upper crustal velocity structure of Santorini volcano and the surrounding region, Hellenic volcanic arc (Heath et al., 2019)
- Author(s): Hooft, Emilie; Heath, Benjamin; Toomey, Douglas
- Description: This data set consists of a 3-D tomographic model of the P-wave seismic velocity structure of the upper 4 km of the crust of Santorini caldera and the surrounding region. The model was derived from active-source data acquired during the PROTEUS 3-D seismic tomography experiment conducted during Langseth cruise MGL1521 in 2015 (chief scientists Emilie Hooft, Doug Toomey, & Paraskevi Nomikou). The model and results are described in Heath et al. (2019). The data was collected using a dense amphibious array of >14,300 marine sound sources from a 6,600 cubic inch 36-component air gun array towed at 12-m depth that were recorded on 156 short-period marine and land seismometers, covering an area 120 km by 45 km. Average shot spacing was ~150 m along ENE-WSW oriented shot lines spaced at 1–2-km intervals and included shot-receiver offsets up to ~115 km. A three-dimensional, iterative tomographic technique (Toomey et al., 1994) was used to invert over 200,000 Pg refraction arrival times to constrain isotropic slowness within the upper crust. The data file is in SEG-Y format with UTM coordinates (zone 35N) and with P-wave velocity on a grid that is spaced 200 m horizontally and 50 m vertically. This model is NOT masked in regions of poor ray coverage and poor resolution. This data set was generated as part of the project called Collaborative research: Crustal magma plumbing of the Santorini volcanic system. Funding was provided by NSF grants OCE14-59794.

Near-bottom AUV Sentry processed bathymetry grids (netCDF format) from the Pythia's Oasis methane seep site
- Author(s): Kelley, Deborah
- Description: Pythia's Oasis is a methane seep site 60 nautical miles off the coast of Oregon. This site is different from other seep sites. It hosts a discrete orifice that has continually vented low-salinity, hydrocarbon-bearing fluids since 2015 and is still active as of August of 2022. The site was discovered in 2015 during a Regional Cabled Array (RCA) Operations and Maintenance Cruise using hull-mounted sonar on R/V Thompson to detect methane bubble plumes in the water column. In 2019, near-bottom swath bathymetry data were collected using a Reson 7125 multibeam sonar system mounted on AUV Sentry during Pythia's Oasis Cruise AT42-17. Six AUV Sentry sonar surveys were conducted. The data were processed and two bathymetric data sets were produced: One is a 2,600 meter by 2,400 meter composite of data from all AUV dives gridded at 1-meter resolution and the other is a 1,500 meter by 800 meter data set from a low-altitude dive gridded at 0.25 meters. The grids presented here are in GMT-compatible netCDF format and the resolution is given in the file name. Funding was provided by National Science Foundation award OCE16-58201.

Santorini Region Multibeam Synthesis, 2015
- Author(s): Hooft, Emilie; Nomikou, Paraskevi; Toomey, Douglas
- Description: This bathymetry synthesis covers the Santorini-Christiana-Amorgos backarc region of the Hellenic subduction zone. The data were collected during the 2015 PROTEUS cruise on R/V Langseth that had the goal of imaging the magma plume structure of the Santorini volcanic system. The PROTEUS experiment deployed a dense array of ocean-bottom and land seismometers that recorded the marine sound source from the ship. The multibeam synthesis was generated by merging hull-mounted EM122 multibeam data collected during the PROTEUS cruise (MGL1521 cruise DOI: 10.7284/906516) with pre-existing data from near the coast and within the caldera of Santorini. Those data sets are from Nomikou et al., 2012 (https://doi.org/10.1016/j.gloplacha.2012.01.001) and Nomikou et al., 2013 (https://doi.org/10.1016/j.tecto.2012.10.001). The file presented here is in GMT-compatible netCDF grid format, with a horizontal resolution of 115m. The raw PROTEUS multibeam data is available at: https://www.marine-geo.org/tools/search/entry.php?id=MGL1521. Funding was provided by National Science Foundation award OCE14-59794.

Near-bottom AUV Sentry raw magnetic data (ASCII format) from 9°50'N, East Pacific Rise (2019, AT42-21)
- Author(s): Parnell-Turner, Ross; Gee, Jeffrey; Berrios-Rivera, Natalia; Fornari, Daniel; McDermott, Jill; Barreyre, Thibaut
- Description: Near-bottom magnetic data was collected at the East Pacific Rise, from 9°50'N, during a total of 20 AUV Sentry dives conducted from R/V Atlantis and R/V Roger Revelle during 2018 Atlantis cruise AT42-06 (three dives); 2019 Atlantis cruise AT42-21 (ten dives); and, 2021 Revelle cruise RR2102 (seven dives). Track lines were spaced 170 m apart, with Sentry about 70 m above bottom, collecting magnetic data using three Applied Physics Systems Model 1540 triaxial fluxgate magnetometers mounted on AUV Sentry. Sentry navigation was obtained using a 300 kHz Teledyne Doppler velocity log (DVL) and a Sonardyne AvTrak2 ultra-short baseline (USBL) acoustic positioning system, combined with an iXblue Phins inertial navigation system (INS), and a Paroscientific 8B7000-I Digiquartz depth sensor. The magnetic data are in ASCII text format, with one file each for top, port, and starboard magnetometers. Each ASCII file contains 11 columns, as follows: lon (degrees), lat (degrees), time (unix time, seconds), depth (m), altitude (m), roll (degrees), pitch (degrees), heading (degrees), X, Y, Z components of magnetic field strength (in oersted, i.e. x10^5 nT). Note that the magnetic data are X,Y,Z in sensor coordinates. The Sentry dive number and magnetometer mount point location is given in the file name. The three ASCII files for each dive correspond to one combined MATLAB file in an associated data set.

Shapefile of processed results from surface x-ray florescence (XRF) analysis of sediment grab samples, Long Island Sound mapping project Phase II
- Author(s): Nitsche, Frank, O; Kenna, Timothy; McHugh, Cecilia
- Description: Sediment grab samples were taken in summer of 2017 and 2018 using a modified van Veen grab sampler. A sub-sample of the top two centimeters was taken for further lab analysis. Dried and homogenized splits of the samples were analyzed for chemical composition using an Innov-X Alpha series 4000 XRF (Innov-X Systems, Woburn, MA). The results of the measurements are presented as ppm. The XRF analytical protocol included the following elements: P, S, Cl, K, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn As, Se, Br, Rb, Sr, Zr, Mo, Ag, Cd, Sn, Sb, I, Ba, Hg, Pb, Bi, Th, and U. However, only Cl, K, Ca, Ti, Cr, Mn, Fe, Co, Cu, Zn, As, Br, Rb, Sr, Zr and Pb were consistently present at levels above background detection in surficial sediments collected in the LIS Phase II area. The data is presented here as an ESRI shapefile. There is an accompanying Excel spreadsheet. Funding was provided by the Long Island Sound Mapping Fund administered cooperatively by the EPA Long Island Sound Study and the Connecticut Department of Energy and Environmental Protection (DEEP).

Dried and homogenized splits of the samples were analyzed for chemical composition using an Innov-X Alpha series 4000 XRF (Innov-X Systems, Woburn, MA). The results of the measurements are presented as ppm. The XRF analytical protocol included the following elements: P, S, Cl, K, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn As, Se, Br, Rb, Sr, Zr, Mo, Ag, Cd, Sn, Sb, I, Ba, Hg, Pb, Bi, Th, and U. However, only Cl, K, Ca, Ti, Cr, Mn, Fe, Co, Cu, Zn, As, Br, Rb, Sr, Zr and Pb were consistently present at levels above background detection in surficial sediments collected in the LIS Phase II area. The data are presented here as an Excel spreadsheet. There is an accompanying ESRI shapefile.

Sediment chemistry (GeoTIFF grid format) from surface carbon and nitrogen analysis of sediment grab samples, Long Island Sound mapping project Phase II
- Author(s): Nitsche, Frank, O; Kenna, Timothy; McHugh, Cecilia
- Description: Sediment grab samples were taken in summer of 2017 and 2018 using a modified van Veen grab sampler. A sub-sample of the top two centimeters was stored in a jar. Dried and homogenized splits of the samples were sent to the Cornell Isotope Laboratory (COIL) to be analyzed for carbon and nitrogen concentrations as well as stable isotopic compositions. Total carbon (TC), total nitrogen (TN), and δ15N were determined on an aliquot of untreated, dried homogenized sediments. In order to accurately determine total organic carbon (TOC) and δ13C, removal of carbonate is necessary. This was achieved through sequential treatments of the sediments with dilute hydrochloric acid until no bubbling was observed. The acidified sediments were then rinsed in deionized water and re-dried. In the Cornell Lab the samples were analyzed using a NC2500 elemental analyzer interfaced with a Thermo Delta V isotope ratio mass spectrometer (IRMS). ArcGIS Pro empirical kriging has been used to interpolate values for organic carbon, total carbon, nitrogen, d13C and d15N isotope content onto a 50 m raster. The interpolated raster has been clipped to fit the extent of the phase 2 survey area. The final raster data files are in GeoTIFF grid format with UTM-18 N projection.Funding was provided by the Long Island Sound Mapping Fund administered cooperatively by the EPA Long Island Sound Study and the Connecticut Department of Energy and Environmental Protection (DEEP).

Shapefile of interpreted sedimentary energy environments for the Long Island Sound mapping project Phase II
- Author(s): Nitsche, Frank, O; Kenna, Timothy; McHugh, Cecilia
- Description: This data set contains interpreted polygons describing different sedimentary energy environments of the Long Island Sound mapping project Phase II. This data set is the result of manual interpretation of detailed bathymetry data and resulting seafloor morphology, backscatter data, sediment core analysis results, and interpretation of sub-bottom data. It distinguishes high, low, and moderate energy environments, which can be caused by current and wave action. The outline of polygons was based on manual interpretation mostly following morphological and backscatter boundaries. Interpretation was cross-checked with sediment grab and core information. Polygon outlines are based on morphology and backscatter data that have 1 m pixel resolution, but interpretation could be several pixels (~ +/-10 m) in each direction, since the exact boundary is not always clear. Small pockets of different environments might not have been distinguished. The data is presented here as an ESRI shapefile in UTM-18 N projection.

Shapefile of interpreted sediment texture distribution for the Long Island Sound mapping project Phase II
- Author(s): Nitsche, Frank, O; Kenna, Timothy; McHugh, Cecilia
- Description: This data set contains interpreted polygons describing different sediment texture distribution of the Long Island Sound mapping project Phase II area. This data set is the result of manual interpretation based on surface grab grain size analysis combined with detailed bathymetry and backscatter data. The outline of polygons was based on manual interpretation using grain size data from sediment grab analysis and mostly following backscatter boundaries. There were smaller areas with different backscatter signal, for which there were no grab samples for ground verification. Changes in the backscatter values do not always correspond to the observed grain size results. In these cases, grain size results from grabs were used as the main guidance. Polygon outlines are based on backscatter data that have 1 m pixel resolution, but interpretation could be several pixels (~ +/-10 m) in each direction, since the exact boundary is not always clear. Small pockets of different environments might not have been distinguished. The data is presented here as an ESRI shapefile in UTM-18 N projection.

- Author(s): Nitsche, Frank, O; Kenna, Timothy; McHugh, Cecilia
- Description: Sediment grab samples were taken in summer of 2017 and 2018 using a modified van Veen grab sampler. A sub-sample of the top two centimeters was stored in a jar. Dried sub-samples samples were analyzed for grain size. First, the samples were treated with hydroperoxide to remove organic components. Then, the sample was passed through a series of standard sieves representing Phi sizes with the smallest being 64 µm. The content of each sieve was dried and weighed. If there was sufficient fine material (< 64 µm), this fine fraction was further analyzed using a Sedigraph system. The results of sieving and sedigraph analysis have been combined and the percentages for gravel, sand, silt and clay were determined following the Wentworth scale. In addition, other statistics including mean, median, skewness and standard deviation are calculated using the USGS GSSTAT program. The results of the LDEO/Queens College grain size analysis have been combined with data collected by the LISMARC group and analyzed by USGS. Based on the different percentages, sediment classifications are determined following the Schlee and the Falk systems. These results are also translated into the CMACS systems. The data is presented here as an ESRI shapefile. There is an accompanying Excel spreadsheet.

LIS Phase II seafloor mapping: Sidescan images (GeoTIFF format), eastern Long Island Sound (2017-18)
- Author(s): Flood, Roger
- Description: Seafloor sidescan data provides important information on water depth and on the character of features on the seafloor to improve our understanding of benthic habitat. Sidescan and multibeam sonar data was collected in 2017-2018 during field surveys by SoMAS, Stony Brook University, in eastern Long Island Sound as part of the Phase 2 of the Long Island Sound Cable Fund Benthic Habitat Mapping Project. The sidescan files in this data set are in GeoTIFF image format and cover 10 of the 27 Survey Blocks assigned to SoMAS. The values of sidescan acoustic backscatter reported in these images depends somewhat on the equipment used and the computer processing that is done in creating the backscatter images. Acoustic backscatter data recorded depends on the azimuth of the sonar track so the final images tried to keep acoustic data collected in a similar orientation. The sidescan sonar data was collected with a pole-mounted system and there was some small across-track amplitude variation due to the instrument roll and there are some residual along-track amplitude variations related to the sonar beam pattern. Although no quantitative analysis was done, the sidescan backscatter data reported during this project is qualitatively similar to that reported by NOAA in NCEI Dataset 0167531 when the image DN values are appropriately stretched. The data is not to be used for navigation. The sidescan field surveys were performed in December 2017 to March 2018 (file names DM). The data was collected on the SoMAS Research Vessel Donald W Pritchard using a pole-mounted EdgeTech 272-TD system which was operated at 100 kHz. All field programs used an Applanix motion sensor system for vessel motion and heading, GPS positions corrected using data from the ACORN RTN (UConn) system, vessel elevations determined using GPS RTN elevations supplemented by scaled and offset land-based water-level measurements, and sound velocity profiles collected using an AML BASEX probe. The sidescan data was recorded in xtf format and processed using programs in the SwathEd program suite developed at the University of New Brunswick (UNB) with modifications done at Stony Brook University. The sonar position, altitude and orientation (heading, roll and pitch) were merged with the sonar data using values recorded by the multimbeam system operating at the same time. The xtf files where re-written with updated sonar navigation, altitude, heading, roll and pitch and those files have been archived. A slant-range correction was made assuming a flat sea floor and the sonar values were plotted on a 1 m grid but only the data closest to a ship track was plotted. The ship tracks used in the mosaic were selected to have consistent orientations and to avoid crossing lines. A correction was applied to the sidescan sonar data based on fish height and slant range to correct signal levels for sonar beam pattern, attenuation and angle-of-incidence but some along-track signal anomalies exist in the map grids. The final maps were made using the corrected signal levels. No correction was made for instrument roll and there is some striping in the sonar mosaics because of the sonar roll. The 8-bit sonar mosaics were imported to ArcMap as tif files and exported as georeferenced GeoTIFFs. Horizontal positions are accurate to about 1 m. The data files show the conditions at the time of the survey in 2017-2018. The full suite of SoMAS mapping comprises four components: multibeam bathymetry (26 maps), bathymetry hillshade (26 maps), multibeam backscatter (26 maps), and sidescan sonar backscatter (9 maps), for a total of 87 maps. The multibeam bathymetry and backscatter data were integrated by NOAA into project-wide maps that can be found at NCEI (Dataset 0167531 version 2.2, https://doi.org/10.25921/tgp1-w632).

LIS Phase II seafloor mapping: Acoustic Backscatter images (GeoTIFF format), eastern Long Island Sound (2017-18)

- Description: Seafloor bathymetry and acoustic backscatter data provides important information on water depth and on the character of features on the seafloor to improve our understanding of benthic habitat. Multibeam sonar data was collected in 2017-2018 during field surveys by SoMAS, Stony Brook University, in eastern Long Island Sound as part of the Phase 2 of the Long Island Sound Cable Fund Benthic Habitat Mapping Project. The acoustic backscatter files in this data set are in GeoTIFF image format and cover the 27 Survey Blocks assigned to SoMAS plus a site in deeper water (Barchans). The backscatter images were created using the program QPS FMGT using multibeam track lines that had been edited and processed by CARIS HIPS and SIPS. The program corrects the sonar data to remove cross-track variations in signal levels. Two different multibeam systems were used to collect the data reported for this study and the data values from the two systems were compared in areas where data sets overlapped. The results from the EM3000D survey were offset and scaled so that the backscatter distributions in the overlap areas were similar. 8-bit multibeam backscatter grids were exported as GeoTIFF images. For all the images reported, higher backscatter values are shown in a lighter color and lower backscatter are shown in a darker color. The 2017-2018 SoMAS surveys have few gaps except for 13_JJ (a compilation of transit tracks that overlap the grid 13_DM) and Barchans (lines that image barchan dunes that are migrating across the seafloor). The data is not to be used for navigation. The field surveys were performed in December 2017 to March 2018 (file names DM) and June-July 2018 (file names JJ). The data was collected on the SoMAS Research Vessel Donald W Pritchard using an EM3000D echo-sounder for the surveys from December, 2017 through March, 2018, and using an EM2040cD (dual-head) echo-sounderfor data collected in June and July, 2018. All field programs used an Applanix motion sensor system for vessel motion and heading, GPS positions corrected using data from the ACORN RTN (UConn) system, vessel elevations determined using GPS RTN elevations supplemented by scaled and offset land-based water-level measurements, and sound velocity profiles collected using an AML BASEX probe. Bathymetry data was processed using CARIS HIPS and SIPS (version 10.4). Data points were edited to remove spurious bed elevations and sound-velocity refraction corrections were applied. Data values were gridded at 1 m horizontal resolution using the Swath Angle gridding algorithm into a series of 26 base maps (resolution is 2 m for the 2018 Barchans file). The 32-bit GeoTIFF gridded base maps are projected in NAD_1983_2011_UTM_Zone_18N and seafloor elevations are reported in meters relative to NAVD-88. Vertical elevations are accurate to about 0.1 to 0.2 m. Elevations may be less accurate at the outer edges of the swath where refraction artifacts can occur. Horizontal positions are accurate to about 1 m. The data files show the conditions at the time of the survey in 2017-2018. The full suite of SoMAS mapping comprises four components: multibeam bathymetry (26 maps), bathymetry hillshade (26 maps), multibeam backscatter (26 maps), and sidescan sonar backscatter (9 maps), for a total of 87 maps.

LIS Phase II seafloor mapping: Bathymetry grids (GeoTIFF format), eastern Long Island Sound (2017-18)
- Author(s): Flood, Roger
- Description: Seafloor bathymetry provides important information on water depth and on the character of features on the seafloor to improve our understanding of benthic habitat. Multibeam sonar data was collected in 2017-2018 during field surveys by SoMAS, Stony Brook University, in eastern Long Island Sound as part of the Phase 2 of the Long Island Sound Cable Fund Benthic Habitat Mapping Project. The bathymetry grids in this data set are in GeoTIFF grid format and cover the 27 Survey Blocks assigned to SoMAS plus a site in deeper water (Barchans). The 2017-2018 SoMAS surveys have few gaps except for 13_JJ (a compilation of transit tracks that overlap the grid 13_DM) and Barchans (lines that image barchan dunes that are migrating across the seafloor). The data is not to be used for navigation. The field surveys were performed in December 2017 to March 2018 (file names DM) and June-July 2018 (file names JJ). The data was collected on the SoMAS Research Vessel Donald W Pritchard using an EM3000D echo-sounder for the surveys from December, 2017 through March, 2018, and using an EM2040cD (dual-head) echo-sounder for data collected in June and July, 2018. All field programs used an Applanix motion sensor system for vessel motion and heading, GPS positions corrected using data from the ACORN RTN (UConn) system, vessel elevations determined using GPS RTN elevations supplemented by scaled and offset land-based water-level measurements, and sound velocity profiles collected using an AML BASEX probe. Bathymetry data was processed using CARIS HIPS and SIPS (version 10.4). Data points were edited to remove spurious bed elevations and sound-velocity refraction corrections were applied. Data values were gridded at 1 m horizontal resolution using the Swath Angle gridding algorithm into a series of 26 base maps (resolution is 2 m for the 2018 Barchans file). The 32-bit GeoTIFF gridded base maps are projected in NAD_1983_2011_UTM_Zone_18N and seafloor elevations are reported in meters relative to NAVD-88. Vertical elevations are accurate to about 0.1 to 0.2 m. Elevations may be less accurate at the outer edges of the swath where refraction artifacts can occur. Horizontal positions are accurate to about 1 m. The data files show the conditions at the time of the survey in 2017-2018. The full suite of SoMAS mapping comprises four components: multibeam bathymetry (26 maps), bathymetry hillshade (26 maps), multibeam backscatter (26 maps), and sidescan sonar backscatter (9 maps), for a total of 87 maps. The multibeam bathymetry and backscatter data were integrated by NOAA into project-wide maps that can be found at NCEI (Dataset 0167531 version 2.2, https://doi.org/10.25921/tgp1-w632). Funding for this study was provided by the Long Island Sound Seafloor Mapping Fund administered cooperatively by the EPA Long Island Sound Study and the Connecticut Department of Energy and Environmental Protection (DEEP).

Sediment Geochemistry Data derived from Gravity Cores acquired as part of Long Island Sound mapping project Phase II
- Author(s): Kenna, Timothy; Nitsche, Frank, O; McHugh, Cecilia
- Description: Processed results from of chemical composition of the sediment core as measured with the Lamont ITRAX Core Scanner (Cox Analytical Systems, Mölndal, Sweden). For XRF measurements, an X−ray tube equipped with a molybdenum anode was operated at a voltage of 30kV and a current of 55mA. Each measurement was made for 30s integrated over a depth interval of 0.5cm by 17mm wide. After scanning was complete, any spectra flagged as invalid were removed and all remaining spectra were summed into a single spectrum. A full spectrum fundamental parameter peak fitting program, provided by the manufacturer, was used to calculate individual elemental abundances in terms of element rates (i.e., cps/mA). Variables in the fundamental parameter algorithm were adjusted to minimize the difference between the measured spectra and the model fit. Once the fitting routine was complete, the optimized parameters were used to calculate down-core elemental rates. The analytical uncertainty of the element signals is estimated based on the dead time corrected total counts for each element. Prior to calibration, elemental rates were first normalized to the coherent scattering peak signal to account for matrix variability and then standardized for each core/each element by subtracting the average element rate and dividing by the standard deviation of the element rate. The data are presented as Excel spreadsheet with one worksheet per core. DOI: 10.26022/IEDA/331159
Physical Properties Derived from Gravity Cores acquired during Long Island Sound Mapping Project Phase II
- Author(s): Nitsche, Frank, O; Kenna, Timothy; McHugh, Cecilia
- Description: Physical Property data of the sediment cores collected with a gravity corer as part of the Long Island Sound mapping project Phase II. Physical properties were measured at 1 mm intervals using a GEOTEK Multi-Sensor Core Logger. Properties measured included density, porosity and magnetic susceptibility. In order to precisely co-register information from the different sensors, each core was run in a custom sample holder equipped with density, height, and distance markers, as well as wet bulk density calibration section. In order to achieve high-resolution density measurements, the window on the NaI detector, used to measure gamma ray attenuation, was modified to a 1 mm x 20 mm slit using a custom-made lead insert. We further modified the system by reconfiguring the laser displacement sensors to make precise, non-contact core thickness deviation measurements, which are required to estimate wet bulk density from the gamma attenuation signal. Magnetic susceptibility was measured using a Bartington MS2E sensor with a probe diameter of 25mm. The Excel spreadsheet has one worksheet per core. DOI: 10.26022/IEDA/331158

Sediment Core Images from samples acquired as part of the Long Island Sound Mapping Project Phase II
- Author(s): Nitsche, Frank, O; Kenna, Timothy; McHugh, Cecilia
- Description: Images of the sediment cores collected as part of the Long Island Sound mapping project Phase II. The images were taken of on split cores at the Lamont core repository using the Itrax imaging system and converted to jpeg. The images have been cropped to fit closely to the core extent. Sediment cores provide information on changes in the sediment environments over time including periods of deposition or erosion, as well as changes in chemical composition with time. Detailed images of the sediment cores provide information on layering and visual changes and disturbances along the core. This information is guiding the sediment environment interpretation. Funding was provided by the Long Island Sound Mapping Fund administered cooperatively by the EPA Long Island Sound Study and the Connecticut Department of Energy and Environmental Protection (DEEP).

First arrival tomography-derived velocity models for Oneida Lake, New York
- Author(s): Zaremba, Nicholas; Scholz, Christopher
- Description: The data set contains velocity models derived from first arrival seismic tomography methods applied to a seismic survey collected for reflection seismic purposes. The original data set was collected as a reflection seismic survey and therefore the data set did not contain forward and reverse shots. Additionally, unlike most seismic tomography surveys, the seismic source and the hydrophones or receivers remained at a constant distance (e.g. the source was always the same distance from channel 1 or channel 144). The source and streamer (array of receivers) were towed behind the vessel and the source or air guns were fired every 6.25 meters. Shot gathers in SEG-Y format were imported into the Geogiga DW TOMO software in 10 shot increments with spacings of ~62.5 meters. This provided a spatially-dense data set for every line, with overlapping ray paths. This software uses ray tracing or the shortest path method in the forward modeling process (Moser, 1991). The forward model or initial velocity model is a sub-surface velocity model defined by the user. The intent of the tomography-derived velocity models was to independently confirm results from seismic reflection data, as well as provide information on the depth to basement in areas where reflection data failed to image the sub-surface stratigraphy. Therefore, a priori data from the reflection data set was limited in the tomography inversion process. The initial model contained a surface velocity of 1350 m/s and increased to 1600 m/s over a depth of 15 meters. Below 15 meters the model increased by 390 m/s every 1 meter to reach a velocity of 5500 meters at 25 meters depth. The same forward model was used for every line, and each line was subjected to 9 iterations with a maximum disturbance of 75%. The inversion process used an algorithm adapted from Toomey et al. (1994) which accounts for previous knowledge such as the prior iteration, smoothing parameters, and travel time uncertainties which are established by the user. Following careful parameter testing, the smoothing parameters chosen for use in the algorithm were 3.75 m for the vertical smoothing, 15.5 m for the horizontal smoothing, and a picking uncertainty of 1 ms. The velocity models are in ASCII text file format and each text file is named after the corresponding seismic reflection profile. In the text files, the first column is depth in meters, the second column is velocity in meters/second, the third column is UTM northing and the fourth is UTM easting (both in meters, UTM zone 18N). A total of 13 lines were processed using the first arrival tomography technique. It should be noted that data coverage or ray path density is much lower for the first few hundred meters of each line. Therefore, the beginning and end of each velocity model should be examined carefully and likely removed from the survey. The data files were generated as part of a project called P2C2: A High Resolution Paleoclimate Archive of Termination I in Oneida Lake and Glacial Lake Iroquois Sediments.

Images for processed seismic profiles 02, 11, and 15 (JPEG format) across the Santorini-Amorgos Tectonic Zone from Poseidon cruise POS338 (2006)
- Author(s): Hubscher, Christian; Preine, Jonas
- Description: In this active-source experiment at the Santorini-Amorgos Tectonic Zone, multi-channel seismic reflection data was collected during Poseidon cruise POS338 in 2006 (chief scientist Prof. Dr. Christian Hübscher, University of Hamburg). The airgun seismic source was a single G.I. gun that was used in true G.I. mode (Injector volume: 45 cubic inches; Generator volume: 105 cubic inches) producing a signal of 100 Hz main frequency. The seismic shot data was recorded with a 24-channel streamer of 600 m length (25 m channel spacing), and stored in SEG-Y format. The processed seismic profile images presented here are in JPEG format. Processing of these data comprised trace-editing, simple frequency filtering (10-500 Hz), suppression of a receiver-ghost signal by predictive deconvolution, surface-related multiple elimination as well as spherical divergence correction, pre-stack time migration followed by top-muting and white-noise removal. These data have a main frequency of 60 Hz indicating a vertical resolution of approx. 8-15 m.This processed seismic data set is interpreted in Preine et al., Tectonics, 2022. The study was funded with German Research Foundation DFG grant HU690/25-1. DOI: 10.26022/IEDA/331029

Microseismicity catalog of westernmost Gofar transform fault, East Pacific Rise, 2008
- Author(s): Gong, Jianhua; Fan, Wenyuan
- Description: This microseismicity catalog is derived from data retrieved from ocean-bottom seismometers deployed in 2008 as part of the Quebrada-Discovery-Gofar (QDG) Transform Fault Experiment. The data file is in ASCII text format. The first row is a column header that describes the content of the catalog: Earthquake origin time, latitude, longitude, depth, and local magnitude. Not all earthquakes have a local magnitude estimate because of the selection criteria. Details of the earthquake location methodology and location interpretations can be found in the paper "Seismicity, fault architecture, and slip mode of the westernmost Gofar transform fault" by Gong and Fan, 2022, JGR. The data set was generated as part of the projects called Capturing 4D Variations in Stress, Slip, and Fault-Zone Material Properties: The 2019-2021 Gofar Transform Fault Earthquake Prediction Experiment; and, CAREER: Using seismic sources to probe megathrust fault conditions. The project was funded by NSF awards OCE-1833279 and EAR-2143413. DOI: 10.26022/IEDA/331024

- Author(s): Bangs, Nathan; Han, Shuoshuo; Bell, Rebecca; Barker, Daniel; Aria, Ryuta; Kodaira, Shuichi; Edwards, Joel; Tobin, Harold; Moore, Gregory; Henrys, Stuart; Bassett, Daniel
- Description: This is the velocity model used for the 3D PSDM seismic volume that is available here. It was constructed by CGG from streamer data and 97 OBS provided by JAMSTEC. The velocity model was produced by 3D full waveform and tomographic inversion that included tilted transverse isotropy (TTI) (details are provided in the associated processing report).The accompanying information document describes the 3D grid parameters including bin grid origin and orientation for workstation loading, the Data Parameters, the SEG-Y trace header, and the processing sequence. Note that the volume is sampled at every 3rd inline and every 4th crossline. The data set was generated as part of the project called "A community 3-D seismic investigation of fault property controls on slow slip along the Hikurangi megathrust". Funding was provided through NSF awards: OCE15-58440, OCE15-58574, OCE15-59008, OCE15-59298. DOI: 10.26022/IEDA/331023

- Author(s): Bangs, Nathan; Han, Shuoshuo; Bell, Rebecca; Barker, Daniel; Aria, Ryuta; Kodaira, Shuichi; Edwards, Joel; Tobin, Harold; Moore, Gregory; Henrys, Stuart; Bassett, Daniel
- Description: This is the prestack depth migrated seismic reflection data volume that was produced from multi-channel seismic lines acquired during the Langseth cruise MGL1801 as part of the NZ3D Hikurangi margin project in 2018. This SEG-Y file is a 3D migration produced by CGG in Singapore using a Kirchhoff 3D prestack depth migration algorithm. This volume includes advanced signal processing to remove multiples, source and receiver ghost, and other artifacts (see associated processing report for details). The volume was migrated after signal processing using seismic velocities derived from streamer data and 97 OBS provided by JAMSTEC. The velocity model was constructed as a 3D anisotropic (TTI) model using 3D full waveform and tomographic inversion (details are provided in the processing report, and the model is available here as a linked data set). The accompanying information document describes the 3D grid parameters including bin grid origin and orientation for workstation loading, the Data Parameters, the SEG-Y trace header, and the processing sequence.

Pressure and temperature time-series data from the CORK in Hole 395A in North Pond acquired from 1997-2007
- Author(s): Becker, Keir; Davis, Earl
- Description: This dataset was acquired with a pressure-temperature logging system deployed in the original CORK installed in July 1997 in Hole 395A in North Pond on the western flank of the Mid-Atlantic Ridge during ODP Leg 174B (Becker et al., 2001). The system included Paroscientific model 8B7000-110 borehole and seafloor pressure gauges and a ten-thermistor sensor cable extending down to nearly 600 m below seafloor. Data were accessed during dives of the manned research submersibles Nautile in 1998 and Alvin in 2001, and when the system was recovered during IODP Expedition 336 in 2011. The data file is in tab-delimited Text File (ASCII) format recorded every hour. Each line includes date/time, borehole pressure, seafloor pressure, temperatures in °C of 8 valid downhole thermistor readings and bottom-water temperature from a matching thermistor in the data logger. Temperatures were obtained from raw binary data by applying a logger count to resistance calibration and individual thermistor resistance to temperature calibrations. Support for acquisition of the sensor string and 1998/2001 submersible dives was provided by NSF award OCE-9530426 (K. Becker, PI) Instrumented borehole seals for 1996 ODP drilling on the Juan de Fuca Ridge (modified after one year to include the 395A CORK). Long-term pressure and temperature data from Hole 395A are presented by Becker et al. (2022). DOI: 10.26022/IEDA/330948
Heat flow data from the Pescadero Basin, Gulf of California (2021, ROV SuBastian, FK210922)
- Author(s): Negrete-Aranda, Raquel; Neumann, Florian; Harris, Robert
- Description: This data set consists of thermal gradients and thermal conductivity to compute the heat flow in Pescadero Basin, Gulf of California. The data have been processed to convert from resistance to temperature using calibrations for each thermistor. Heat flow was estimated by combining the thermal gradient and thermal conductivity using the Bullard method. The data set was collected using a custom 1-m long ROV heat flow probe from Andrew Fisher, UC Santa Cruz. The heat flow probe was deployed on ROV SuBastian dives S0463-S0481 during Falkor cruise FK210922, operated by Schmidt Ocean Institute. Each deployment of the heat flow probe lasted approximately 15 minutes. The data file is in tab-separated ASCII text format with column headers and units. Funding was provided through awards from Schmidt Ocean Institute and internal funding from MBARI, CICESE, UABC, and CALTECH. DOI: 10.26022/IEDA/330947

Seismic velocity model images, Eastern North American Margin Community Seismic Experiment (ENAM CSE)
- Author(s): Shuck, Brandon; vanAvendonk, Harm; Becel, Anne
- Description: This data set presents images of each seismic velocity model and corresponding ray coverage. The top panels show the Derivate Weight Sum (DWS) of each model, which is a measure of ray density in the model grid space. Likewise, the density of bounce points on each reflecting boundary is shown by the relative size of black circles. DWS can be used to assess areas of poor ray coverage and hence use caution when interpreting velocities or layer boundary depths in these domains. Here, the base10 logarithm of DWS for each model is taken and the corresponding colormap and size of circles along boundaries are normalized to span the minimum and maximum of these values. This normalization is done for each individual model – thus, the plots show relative areas of good and bad ray coverage within a single model but should not be used to quantitatively compare ray density from model to model. Velocity models are plotted with 1 km/s contours. These image files are in PNG format. This data set was generated as part of the projects called Seismic study of mantle deformation and melt extraction during continental breakup in the ENAM primary site; and, Final stages of breakup and early spreading history of the Eastern North America passive margin from multichannel seismic data. Funding was providing through NSF awards OCE15-51717 and OCE15-51807. DOI: 10.26022/IEDA/330944
Seismic velocity model geometries, Eastern North American Margin Community Seismic Experiment (ENAM CSE)
- Author(s): Shuck, Brandon; vanAvendonk, Harm; Becel, Anne
- Description: This data set presents the velocity model geometry, and the data files describe the spatial link between geographic coordinates and cartesian coordinates of the velocity models. The models were constrained by traveltime tomography of active-source Ocean Bottom Seismometers data along three profiles from the Eastern North American Margin Community Seismic Experiment (ENAM CSE). P-wave velocity models for Line 1, Line 2, and Line 3 are included as well as a S-wave velocity model for Line 3. Collectively, these tomographic velocity images reveal subsurface properties and information on the ancient rifting event between eastern North America and west Africa during the breakup of Pangea and formation of the Central Atlantic ocean, but may also be relevant for other studies such as modern processes along the margin. The data files are in ASCII format. Columns are: Longitude (decimal degrees), Latitude (decimal degrees), X-coordinate (km), Water depth (km). This data set was generated as part of the projects called Seismic study of mantle deformation and melt extraction during continental breakup in the ENAM primary site; and, Final stages of breakup and early spreading history of the Eastern North America passive margin from multichannel seismic data.

Seismic velocity model layers, Eastern North American Margin Community Seismic Experiment (ENAM CSE)
- Author(s): Shuck, Brandon; vanAvendonk, Harm; Becel, Anne
- Description: This data set presents the velocity model interfaces. The velocity models were constrained by traveltime tomography of active-source Ocean Bottom Seismometers data along three profiles from the Eastern North American Margin Community Seismic Experiment (ENAM CSE). P-wave velocity models for Line 1, Line 2, and Line 3 are included as well as a S-wave velocity model for Line 3. Collectively, these tomographic velocity images reveal subsurface properties and information on the ancient rifting event between eastern North America and west Africa during the breakup of Pangea and formation of the Central Atlantic ocean, but may also be relevant for other studies such as modern processes along the margin. These data files are in ASCII format and describe the coordinates of layers within the velocity models. Each model consists of four layers (top to bottom): siliciclastic sediments, carbonaceous sediments, crust, mantle. Layer coordinates are exported every 180 meters in the X direction. Columns are: Layer ID, X-coordinate (km), Z-coordinate (km). Layer ID: 1 = seafloor, 2 = top of carbonates, 3 = top of basement, 4 = Moho. This data set was generated as part of the projects called Seismic study of mantle deformation and melt extraction during continental breakup in the ENAM primary site; and, Final stages of breakup and early spreading history of the Eastern North America passive margin from multichannel seismic data.

Seismic velocity grids, Eastern North American Margin Community Seismic Experiment (ENAM CSE)
- Author(s): Shuck, Brandon; vanAvendonk, Harm; Becel, Anne
- Description: These velocity models were constrained by traveltime tomography of active-source Ocean Bottom Seismometers data along three profiles from the Eastern North American Margin Community Seismic Experiment (ENAM CSE). P-wave velocity models for Line 1, Line 2, and Line 3 are included as well as a S-wave velocity model for Line 3. Collectively, these tomographic velocity images reveal subsurface properties and information on the ancient rifting event between eastern North America and west Africa during the breakup of Pangea and formation of the Central Atlantic ocean, but may also be relevant for other studies such as modern processes along the margin. The data files are in ASCII format and the velocity models are exported every 180 meters in the horizontal X direction, and every 90 meters in the vertical Z direction. Columns are: X-coordinate (km), Z-coordinate (km), Vp (km/s). The X-coordinate of Line 1 and Lines 2 models is zero at the coastline. Model Z-coordinates are positive and increasing with depth. Line 1 and Line 2 models start at one kilometer above sea level (-1.0) due to the landward extension of the profiles; however, the onshore domain is not shown or archived here due to poor ray coverage. For the line 3 velocity model, the data file columns are: X-coordinate (km), Z-coordinate (km), Vs (km/s). This velocity model was produced by traveltime inversion of shear-waves that were converted at the seafloor. Note that these phases traveled as P-waves throughout the water column, hence there is a corresponding P-wave velocity of ~1.5 km/s above the seafloor. This data set was generated as part of the projects called Seismic study of mantle deformation and melt extraction during continental breakup in the ENAM primary site; and, Final stages of breakup and early spreading history of the Eastern North America passive margin from multichannel seismic data.

Processed CHIRP SEG-Y sub-bottom profile images from the Sacramento-San Joaquin Delta, CA, October 2017
- Author(s): Klotsko, Shannon; Maloney, Jillian; Watt, Janet
- Description: CHIRP sub-bottom data were collected in the Sacramento-San Joaquin Delta, CA in October 2017. The purpose of these data was to image any deformation features in the shallow sediments associated with faults in the region and identify locations for sediment sampling. These sub-bottom profile processed images are in JPEG format and are derived from SEG-Y files that were collected with an Edgetech 3200-XS SB-512i instrument in a floating frame towed by a pontoon boat with the bottom of the transducer ~1 meter below water surface. Data were lightly processed, including match filtering onboard the instrument, and computing the envelope of the correlate. Gas throughout the data set disrupts the signal. Funding was provided by the Delta Stewardship Council Delta Science Program under Grant #1167. DOI: 10.26022/IEDA/330932

Gridded bathymetry for Lake Malawi (Nyasa), East Africa (within Malawi, Tanzania, Mozambique)
- Author(s): Scholz, Christopher; Lyons, Robert
- Description: This gridded bathymetry is the best publicly available rendering of the bathymetry of the entirety of the lake generated to date. The results of this work are presented in: Lyons, et al., 2011, Late Quaternary stratigraphic analysis of the Lake Malawi Rift, East Africa: an integration of drill-core and seismic reflection data, Palaeogeography, Palaeoclimatology, Palaeoecology, v. 303, pp. 20-37. The gridded bathymetry data were generated from lake floor horizons interpreted from legacy multichannel and single-channel seismic reflection data from as early as 1985, and not from hydrographic surveys. Accordingly there is considerable error associated with lake floor horizon picks. Primary data quality varied widely. Positioning information is derived from autonomous GPS data or from Transit Satellite data collected during seismic acquisition, and positioning quality varies widely. See the Lyons et al., 2011 paper for specific information on primary data. Gridding and masking was performed in GMT using the surface function after the data was meaned in blocks of 15 arcsecond (~450m) bins to reduce spatial aliasing and eliminate redundant data. This grid is a minimum curvature solution (i.e. T = 0). Depths are in meters, positive downwards, and are relative to the lake surface. The grid is in GeoTIFF grid format. DOI: 10.26022/IEDA/330928

Raw 2-D multichannel seismic reflection SEG-D shot data from Oneida Lake, New York (2019)
- Author(s): Scholz, Christopher; Zaremba, Nicholas
- Description: In July 2019, approximately 217 km of 2-D multichannel seismic reflection data were collected along 27 profiles on Oneida Lake, New York using a 120 channel Seamux™ solid-towed array marine streamer with a 3.125 m group interval and a maximum offset of ~400 meters. Data were recorded in SEG-D format on a NTRS2 recording system. The seismic source was a 4x10 in3 Bolt 2800 LLX airgun array and was towed at ~1 meter depth to allow for venting of seismic source air bubbles. Gun pressures varied from 1500 to 2000 PSI. Air guns were fired every 6.25 m distance using two high resolution (Trimble) GPS receivers for navigation. This geometry provided 30-fold seismic coverage with a common midpoint (CMP) interval of 1.56 m. Record length is 2 seconds and the sample rate is 0.25 ms. These raw field shot data files are in SEG-D format, bundled by seismic line. The files were acquired as part of a project called P2C2: A High Resolution Paleoclimate Archive of Termination I in Oneida Lake and Glacial Lake Iroquois Sediments. Funding was provided through NSF grant EAR18-04460 to Syracuse University. DOI: 10.26022/IEDA/330883
Processed bathymetry images (GeoTIFF image format) derived from Geoswath multibeam data in Eastern Long Island Sound (2017-2018)
- Author(s): Babb, Ivar; Arbige, Dennis
- Description: This data set was acquired in 2017-2018 with a 250 kHz Kongsberg Geoswath Phase Measuring Bathymetry Sonar (PMBS) system mounted in the moon pool of R/V Lowell Weicker. Horizontal accuracy was provided by DGPS augmented by RTK corrections from the Advanced Continuous Operation Reference Network (ACORN). This is a Connecticut statewide system of base stations that provides real-time corrections for GPS equipment, operated by the University of Connecticut through a partnership with CTDOT (http://acorn.uconn.edu). Tides were corrected to MLLW based on tide gauge data from NOAA Tide Station at New London, Connecticut (Station ID: 8461490). Sound velocity profiles (SVP) were conducted every three hours to acquire sound speed data using the UConn Valeport SVP system. Data acquisition was performed using the Geoswath+ acquisition software and saved as .rff files for subsequent post-processing. The system recorded bathymetry and sidescan sonar data along with heave, pitch and roll data from a Seatex MRU-5 mounted on the Geoswath transducer. Positional information for all equipment (GPS, transducer, MRU) offsets and latencies can be found in the CARIS vessel file included with the raw data. Line spacing was set at 25 meters for the majority of the survey area with a 30 meter spacing adopted in deeper areas (information provided in the daily Survey Logs). The bathymetry data files were processed using CARIS software. The data files were acquired and processed in two individual blocks. The final bathymetry files presented here are in GeoTIFF image format, projected in WGS84 UTM 18N (EPSG: 32618) with 1m resolution. The data set was collected and assembled as part of the "The Long Island Sound Seafloor Mapping Initiative Phase II – Eastern Long Island Sound" project conducted by the Long Island Sound Mapping and Research Collaborative (LISMaRC, Principal Investigator: Ivar G. Babb). Funding provided by the Long Island Sound Seafloor Mapping Fund administered cooperatively by the EPA Long Island Sound Study and the Connecticut Department of Energy and Environmental Protection (DEEP).

NZ3D seismic reflection data volume – Preliminary post-stack time migration (PSTM)
- Author(s): Bangs, Nathan; Han, Shuoshuo
- Description: This is the preliminary data volume that was produced from this NZ3D Hikurangi margin project. This SEG-Y file is a post-stack 3D Kirchhoff migration prior to multiple suppression. The volume was produced from multi-channel seismic lines acquired during the Langseth cruise MGL1801 conducted along the Hikurangi margin in 2018.The goal of this preliminary processing was to conduct sufficient processing for an initial assessment of the data and preliminary interpretation. There is no multiple suppression, and the multiple interferes substantially. The results of this preliminary volume were used only for close examination of shallow structures above the seafloor multiple, and an overall assessment of the main structures below the seafloor multiple. Advanced processing to remove multiples, build accurate velocity models, and conduct prestack depth imaging were efforts that followed this initial volume. The accompanying information document describes the 3D grid parameters including bin grid origin and orientation for workstation loading, the Data Parameters, the SEG-Y trace header, and the processing sequence. The data set was generated as part of the project called "A community 3-D seismic investigation of fault property controls on slow slip along the Hikurangi megathrust". Funding was provided through NSF awards: OCE15-58440, OCE15-58574, OCE15-59008, OCE15-59298. DOI: 10.26022/IEDA/330881

Processed Unmigrated Time Stack, Prestack Depth-Migrated, and Depth-to-Time-converted seismic data from the EDGE-302 deep crustal seismic reflection transect of the eastern Aleutian arc-trench
- Author(s): Miller, John; Klaeschen, Dirk
- Description: This data set represents processed Multi-Channel Seismic (MCS) profiles acquired in July 1988 with the Digicon recording vessel Geotide. The four versions of data files presented here, in SEG-Y format, are in progressively advanced stages of processing. Processing was carried out at the GEOMAR Helmholtz Centre for Ocean Research Kiel, Germany using PRAKLA-SEISMOS software on a CONVEX computer. The unmigrated time stack (file EDGE_302_stack.sgy) used a standard processing flow of scaling, multiple removal, deconvolution, filtering, Velocity analysis, Normal Moveout, and Stacking. The initial Prestack depth migration (file EDGE_302_tmig2d.sgy) was then performed using depth focusing analysis on migrated common image gather iteratively to build a velocity field in depth. The final prestack depth migration (file EDGE_302_dmig.sgy) had additional weighting of the amplitudes below the top of the oceanic plate and cleaning of remaining multiple energy applied. The final prestack depth migration was converted to time (file EDGE_302_tmig.sgy). The unmigrated time has a CMP interval of 12.5m; all others are 25m. Additional details for each data file are given in the associated data file details document. The project was supported by National Science Foundation Grant EAR87-21194 and Texaco Oil Company.

Processed 2-D multichannel seismic reflection data from Oneida Lake, New York (2019)
- Author(s): Scholz, Christopher; Zaremba, Nicholas
- Description: In July 2019, approximately 217 km of 2-D multichannel seismic reflection data were collected along 27 profiles on Oneida Lake, New York using a 120 channel Seamux™ solid-towed array marine streamer with a 3.125 m group interval and a maximum offset of ~400 meters. Data were originally recorded in SEG-D format on a NTRS2 recording system. Navigational data and ancillary data (ship speed, depth, etc.) were fed into the external header of each field file. The seismic source was a 4x10 in3 Bolt 2800 LLX airgun array and was towed at ~1 meter depth to allow for venting of seismic source air bubbles. Gun pressures varied from 1500 to 2000 PSI. Air guns were fired every 6.25 m distance using two high resolution (Trimble) GPS receivers for navigation. This geometry provided 30-fold seismic coverage with a common midpoint (CMP) interval of 1.56 m. Record length is 2 seconds and the sample rate is 0.25 ms. The following processing steps were applied to the dataset using SeisSpace/ProMAX Software. Data were initially reviewed in shot mode and noisy traces were edited. Geometry was applied using source and receiver offsets with group and shot intervals, and data were sorted into the CMP domain. Stacking velocities were picked using a combination of velocity semblance plots and constant velocity stacks applied to CMP supergathers. For the constant velocity stacks, supergathers were constructed from 51 CMPs and analyzed in increments of 100 CMPs. Once time-velocity pairs were selected, normal moveout was applied to the full profile data set and the data were stacked.Nested Ormsby bandpass filters of 110-135-1500-1700 Hz and 40-70-1100-1300 Hz were applied to the stacked datasets. Ormsby filter frequencies were picked by executing a careful parameter test where frequencies were altered incrementally until the ideal filter was produced. A post-stack F-K filter was applied to remove steeply dipping noise, and a careful comparison of F-K filtered profiles and raw profiles was conducted. A post-stack Kirchhoff time migration with a 200 ms bottom taper was applied using the RMS stacking velocities picked for each seismic profile. The data files are in SEG-Y format and were generated as part of a project called P2C2: A High Resolution Paleoclimate Archive of Termination I in Oneida Lake and Glacial Lake Iroquois Sediments. Funding was provided through NSF grant EAR18-04460 to Syracuse University. DOI: 10.26022/IEDA/330835

Navigation data for processed 2-D multichannel seismic reflection data from Oneida Lake, New York (2019)
- Author(s): Scholz, Christopher; Zaremba, Nicholas
- Description: These seismic navigation data were collected on Oneida Lake, New York, in July of 2019 during MCS data acquisition. Two high-resolution Trimble GPS receivers mounted on the port bow provided the location of each FFID or shot point. This information combined with the ship/survey geometry, which included the relative location of the airguns and midpoint of all streamer channels, allowed for calculation of the approximate X and Y coordinates in UTM 18N of the air guns and the midpoint for streamer channel 1 (1st channel) through channel 120 (last channel). The navigation data as well as the geometry of the seismic survey were loaded into Landmark SeisSpace/ProMAX software which produced the X and Y coordinates in UTM 18N for each CDP (common depth point). The data files are in ASCII text format and contain the line name, CDP number, and the UTM 18N X,Y coordinates in meters. The files were generated as part of a project called P2C2: A High-Resolution Paleoclimate Archive of Termination I in Oneida Lake and Glacial Lake Iroquois Sediments.

Microseismicity earthquake catalog, Endeavour Segment, Juan de Fuca ridge, 1995-2023
- Author(s): Krauss, Zoe; Wilcock, William
- Description: This microseismicity catalog is derived from three separate local ocean-bottom seismometer networks on the Endeavour Segment of the Juan de Fuca ridge. The earthquake locations in this catalog from the first network, deployed from June-August 1995, are relocations of the Wilcock (2002, doi:10.1029/2001JB000505) earthquake catalog (doi:10.1594/IEDA/306478). Earthquake locations from the second network, deployed from August 2003-October 2006, are relocations of the Weekly et al. (2013, doi:10.1002/ggge.20105) earthquake catalog (doi:10.1594/IEDA/321736). The third network is part of the Ocean Networks Canada NEPTUNE cabled observatory. We include newly-published earthquake locations for this network for August 2016-February 2021 as JdF_Endeavour_earthquake_catalog_v1.txt. The data file is in ASCII text format and the header block describes the content. Not all earthquakes have an estimated moment due to selection criteria. Details of the methods used to locate earthquakes from all three deployments may be found in Krauss et al. (2023, doi:10.1029/2022JB025662). An updated datafile, which includes an extended earthquake catalog from the Ocean Networks Canada NEPTUNE cabled observatory (network code NV) covering August 2016-December 2023, is available as JdF_Endeavour_earthquake_catalog_v2.txt. This version 2 file does not contain earthquakes from 1995 or from 2003-2006. Earthquake moments do not have station corrections applied as in Krauss et al. (2023, doi:10.1029/2022JB025662), but are simply the median of all moment estimates between stations. The data set was generated as part of the project titled "Microearthquakes on the Endeavour Segment, Juan de Fuca Ridge: A Near Real Time Earthquake Catalog for the ONC Cabled Observatory and a Reanalysis of Historical Data". Funding was provided by NSF grant OCE-1833419. DOI: 10.26022/IEDA/330498
T-phase location catalog for equatorial Atlantic ocean, 2011-2015
- Author(s): Parnell-Turner, Ross; Dziak, Robert; Smith, Deborah
- Description: Catalog of T-phase origins from August 2011 to January 2015, located using waveform arrivals recorded by an array of 8 autonomous moored hydrophones and the hydroacoustic station HA10 (Ascension) maintained by the Comprehensive Nuclear-Test-Ban Treaty Organization. Instruments were placed in the Sound Fixing And Ranging (SOFAR) channel. Event locations are expected to be associated with earthquakes on transform faults and spreading segments along the equatorial Mid-Atlantic Ridge. The data file is in ASCII text format and contains a header line that describes the file content. The data set was generated as part of the projects called Seismicity of the Equatorial Mid-Atlantic Ridge and Its Large Offset Transforms; and, Along-Axis Continuity of Oceanic Detachment Faults. Funded was provided by NSF awards NSF EAR-1062238, EAR-1062165, and OCE-1839727. DOI: 10.26022/IEDA/330497

Preliminary 1-meter resolution bathymetric model (ASCII grid format) for the distal South Rift Zone region of Axial Seamount, version as of 31 October 2019
- Author(s): Clague, David; Caress, David; Paduan, Jennifer; LeSaout, Morgane
- Description: This data set (investigators D. W. Caress, D. A. Clague, J. B. Paduan, M. Le Saout) is compiled from data collected on surveys of the South Rift Zone at Axial Seamount between 2011 and 2019 by the MBARI Mapping AUVs. This data set is as published in Le Saout et al., 2022, Faulting and magmatic accretion across the overlapping spreading center between Vance Segment and Axial South Rift, GRL. The bathymetry is interim and to be considered a work in progress. The navigation model underlying this version of bathymetry was generated on 31 October 2019 using the MB-System mbnavadjust program, with which the AUV surveys are tied together. As future data are acquired, the bathymetry coverage will increase and the navigation model will shift. The grid is in ESRI ASCII format in the geographic WGS-1984 coordinate system and has 1-m horizontal resolution, with square cells for use with GIS. Funding for the work was provided through annual grants to MBARI from the David and Lucile Packard Foundation. DOI: 10.26022/IEDA/330466

Audio-quality hydrophone data from Yellowstone Lake - Deep Hole thermal area, August, 2017
- Author(s): Sohn, Robert
- Description: This data set was acquired with a High Tech HTI-90-U hydrophone and sampled at 44.1 kHz (24-bit). The hydrophone and data logger were packaged and lowered to the floor of Yellowstone Lake at a depth of ~115 m from R/V Annie, owned and operated by The Global Foundation for Ocean Exploration. The unit was placed in a weakly venting area of the Deep Hole thermal field. Recording began several hours before the unit was deployed in the lake. Only those files that contain data from the hydrothermal field are archived here. The unit was deployed on August 16, 2017 at the end of a day of field work, prior to departing the study site, and recorded overnight, when noise levels in the lake are lowest. The unit was then recovered the following morning (August 17) prior to the start of field work that day. In addition to data from the sublacustrine environment, ship and propeller noise is clearly audible in the records during deployment and recovery, but noise levels are low during the local (MDT) nighttime hours. The files are in WAV audio file format. Recorder voltage response is 978000 counts/volt. The data were acquired by Robert Sohn (Woods Hole Oceanographic Institution) as part of the Hydrothermal Dynamics of Yellowstone Lake (HD-YLAKE) project, funded by the National Science Foundation, EAR-1516361. All work in Yellowstone National Park was completed under an authorized research permit (YELL-2018-SCI-7018). DOI: 10.26022/IEDA/330446
Processed bathymetry data (GeoTIFF grid format) for Paterson Inlet, Stewart Island, New Zealand
- Author(s): Dagg, Bob
- Description: This processed bathymetry data set was generated from multibeam data obtained from LINZ Data Service. The data file is in GeoTIFF grid format and is in the New Zealand Transverse Mercator 2000 (EPSG:2193) projection. The original multibeam data was collected with a multibeam instrument (model unknown) between August 2008 and March 2009 by a contractor working on behalf of Land Information New Zealand (LINZ). The multibeam line spacing in the original survey was 100m. The original multibeam data was converted to XYZ format and released by LINZ to the University of Otago under the Creative Commons 4.0 license. The XYZ files were uploaded to ArcGIS Pro and converted to a 1m x 1m bathymetric raster grid of Paterson Inlet using the Create ArcGIS TIN and TIN to Raster Toolboxes. This bathymetric grid was created to give students, particularly those at the University of Otago, a way to easily access bathymetric data for the Paterson Inlet, an area that is often used for teaching and research purposes.

Earthquake microseismicity catalog of the Quebrada transform fault system at ~3.7°S, East Pacific Rise, 2008
- Author(s): Gong, Jianhua; Fan, Wenyuan; Parnell-Turner, Ross
- Description: This microseismicity catalog is derived from data retrieved from ocean-bottom seismometers deployed in 2008 as part of the Quebrada-Discovery-Gofar (QDG) Transform Fault Experiment. The data files are in ASCII format. The first row is a column header that describes the content of the catalog: Earthquake origin time, latitude, longitude, depth and local magnitude. Not all earthquakes have a local magnitude estimate because of the selection criteria. Details of the earthquake location methodology and location interpretations can be found in the paper "Microseismicity indicates atypical small-scale plate rotation at the Quebrada transform fault system, East Pacific Rise" by Gong et al., GRL. The data set was generated as part of the projects called Oceanic Transform Faulting: Foreshocks, Seismic and Aseismic Slip on the Quebrada, Discovery and Gofar Transforms; and, Capturing 4D Variations in Stress, Slip, and Fault-Zone Material Properties: The 2019-2021 Gofar Transform Fault Earthquake Prediction Experiment. Funding was provided by NSF awards OCE 0242117 and OCE 1833279. DOI: 10.26022/IEDA/330427
Raw high-temperature time series data from the East Pacific Rise 9°50'N hydrothermal vents M and Q (2004-2006)
- Author(s): Barreyre, Thibaut; VonDamm, Karen; Fornari, Daniel; Parnell-Turner, Ross; McDermott, Jill
- Description: This data set consists of raw hydrothermal high-temperature vent time-series measurements from Multidisciplinary Instrumentation in Support of Oceanography (MISO) vent fluid temperature loggers deployed in 2004 during R/V Atlantis cruise AT11-09 at M vent and Q vent at the East Pacific Rise (EPR), near 9° 51'N. The MISO high-temperature vent fluid loggers used for this study contained two Onset Computer (https://www.onsetcomp.com/) temperature recording chips connected to resistance temperature device (RTD) sensors, each with a resolution of 1°C. The sensing capability of this instrument was limited to the range between 152–408°C because they are 8-bit devices [see Fornari et al. (1998a) for instrument details]. Exit-vent fluid temperatures were recorded continuously over more than 20 months at 36 minute intervals. These raw data files contain the raw data as downloaded from the instruments upon recovery. The files are in tab-separated ASCII format and include a header that defines the data columns: First column = Date Time; Second column = Temperature in Degrees Celsius. In the file names, 623721 and 623731 refer to the ONSET temperature logging chip serial number. The data set was collected as part of the projects called Integrated Studies of Biological Community Structure at Deep-Sea Hydrothermal Vents; Temporal Variations in Hydrothermal Fluid Chemistry at 9-10N East Pacific Rise: Elucidating Ties to Crustal and Biological Processes; Evaluation of EPR Hydrothermal Systems: Causes of Continued Chemical Instability at 9-10 degrees N vs. Stability at 21 degrees N; and, Faunal Survey of Deep-Sea Hydrothermal Vents and Cold Seeps Off Northern California and Oregon. The data acquisition was funded through NSF awards DEB00-72695, OCE00-02458, OCE03-27126, OCE03-27261. Current analysis of these data and ongoing studies of EPR high-temperature vent fluids and time-series temperature measurements are being done with NSF awards OCE18-34797, OCE19-48936, OCE19-49485, OCE19-49938 as part of the projects called EAGER: Early Career Training Cruise Opportunity - East Pacific Rise 9° 50'N; and, Monitoring hydrothermal fluids, crustal permeability and seafloor morphology in preparation for the next volcanic eruption at the East Pacific Rise, 9° 50'N.
