A trusted data repository offering
free public access to a curated collection of marine geophysical
data and metadata related to the formation and evolution of the seafloor and sub-seafloor.
Explore our data holdings to discover research data from around the world.

Academic Seismic Portal
The primary data resource for
field and processed data from active source marine seismic experiments (multi-channel, single-channel, chirp subbottom, sonobuoy)
acquired by the U.S. academic community.

Submersible Data
Submersibles provide important high-resolution geophysical data sets as well as bottom samples, photos and video that
are important for seafloor characterization and ground-truth. Data have been acquired by the National Deep Submergence
Facility (NDSF), the Schmidt Ocean Institute (SOI), and the Monterey Bay Aquarium Research Institute (MBARI).
