Accessing Marine Geology Data
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.
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).
Learn more about the Marine Geology archive.
Index to Marine and Lacustrine Geological Samples (IMLGS)
The IMLGS provides searches of sea floor and lakebed cores, grabs, dredges, and drill samples available directly from participating oceanographic institutions.
The Index also provides links to data and images related to these samples, including direct links to view and download related data at NGDC, at the participating institutons, and external databases like PetDB.
Direct Download of Selected Data Sets
Selected data sets are available for direct download, in addition to being available through searches of the marine geology inventory. These data sets include compilations from many sources, including integrated projects and US and non-US academic, commercial, and government agencies.
More Ways to Access Marine Geology Data from the NGDC Archive
Marine geology data from the NGDC archive are also offered in other forms on other sites.
Examples include goSeabed/dbSeabed/usSEABED,
the National Science Foundation (NSF)-sponsored GeoMapApp, and
the United Nations UNEP Shelf Programme interactive map.
Marine geology data in the NGDC archive were contributed by sources from around the world. Please cite the original source when using these data.
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.
