ECS Data Access

NCEI archives bathymetric, gravity, magnetic, seismic, and geologic sample data from the U.S. coastal waters to the deep ocean. Data collected as part of the U.S. ECS Project are in the public domain and made available as rapidly as possible.

The USGS National Archive of Marine Seismic Surveys (NAMSS) provides seismic and geologic sample data collected by USGS, private industry, and others. The University of New Hampshire's Center for Coastal and Ocean Mapping/Joint Hydrographic Center (UNH CCOM-JHC) collects and processes ECS-funded bathymetric products.
