About this Site

This web site provides data services for the published data of the The U.S. Geological Survey, Coastal and Marine Geology Program (CMGP). Access to CMGP data is provided via Open Geospatial Consortium (OGC) standards services; serving CMGP data to GeoMapApp and Virtual Ocean 2-D and 3-D earth browsing tools, for data integration, visualization and analysis; and metadata catalogs for data discovery. Currently this site contains seismic, sidescan sonar, bathymetry, gravity, magnetic, and lidar data. See our Frequently Asked Questions for more information.
