Building upon the foundation established over the last decade as part of the IEDA data facility, MGDS was re-established as an independent data system. As part of this evolution, the system is being adapted and optimized to be consistent with its modern role as a trusted data repository that provides free public access to a curated collection of marine geophysical data products and complementary data related to understanding the formation and evolution of the seafloor and sub-seafloor.

Lamont-Doherty has become an official branch of the Antarctic Seismic Data Library System (SDLS), which is archiving all marine multi-channel seismic data acquired in the area (south of 60°S) as required by the Antarctic treaty. SDLS libraries maintain DVD copies of and provide access to the seismic data including those that are not yet publicly available from the main SDLS web portal (http://sdls.ogs.trieste.it/) http://sdls.ogs.trieste.it/. The libraries also enhance collaboration between originators of data and potential users. In addition to the library function, we are integrating older seismic data into GeoMapApp.

GeoMapApp 3.0 and GMRT 2.0 released! GeoMapApp 3.0 provides access to a major upgrade to the base topography dataset accessible through GeoMapApp to include the GMRT 2.0, with greatly expanded coverage in the oceans, and the ASTER and NED topography datasets for the global land masses. The ASTER GDEM topography dataset (Japan METI/NASA), provides 30 m resolution for the continents from 83°S to 83°N and replaces the SRTM dataset used in prior GeoMapApp releases. For North America, the even higher resolution NED dataset (USGS) is now accessible, providing topography of the continental U.S. to 10 m resolution. For the oceans, the GMRT v2.0 synthesis includes bathymetric coverage to 100 m resolution from multi-beam bathymetry mapping expeditions and regional gridded compilations from a number of areas and international sources. New data coverage over GMRT 1.0 is focused in the Atlantic and central Pacific with over 100 expeditions added since the prior release. In addition, GMRT v2.0 includes a new 50 m grid resolution layer for the continental shelves and other ocean areas where native resolution of the available sonar data is sufficient. The high resolution bathymetry are merged with the Smith and Sandwell v12.1 global topography compilation, the IBCAO v2.23 for the Arctic, and the BedMap Subglacial Topographic Model of the Antarctic.
Statistics showing the use of GeoMapApp Custom Portals since 2004 are now available.
