Marine Geoscience Data System

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).

Search for ROV data (e.g. Jason and SuBastian)

Search for AUV Data (e.g. Sentry and MBARI Mapping AUV)
