View and Download Data

Marine Geology Searches and Web Services are available for the Marine Geology Inventory and for several individual data sets, including text searches, ArcGIS interactive maps, Web Map Services (WMS), and Web Feature Services (WFS).

The Marine Geology Inventory provides searches of all marine geologic data, digital and analog, archived by NGDC. Search results include links to download all digital data files for free, to view most data reports in .PDF form, and to ordering information for CD-ROMs and posters.

Data in the NGDC archive were contributed by sources from around the world. Please cite the original source when using these data.

CDMP logo Many of the core and seabed photographs and descriptions available here were digitized under Project L-19
of the NOAA Climate Data Modernization Program (CDMP). Project L-19 was a partnership between NGDC and several institutions to digitize, make available, and archive analog data from their collections.

Contribute Data
