About The Data
Marine geophysical surveys gather data about the shape and subsurface geology of the sea floor. Analysis of geological samples (geosamples) collected during these surveys yields additional environmental and paleo-environmental data, and provides "ground truth" for interpretation of geophysical measurements. Geophysical and geosample data combine to provide the information needed to understand Earth's seabed environment and subsurface processes. Learn more...
How to View/Download Data
Most geosample data associated with a specific cruise or sample are discoverable and downloadable using the Index to Marine and Lacustrine Geological Samples (IMLGS), which also provides access to sample material curated by partner institutions. Multi-platform compilations or data reports are accessible using the Marine Geology Inventory.
How to Cite
Always cite the original source when using these data; use the DOI/citation where provided.
More About the Data
Over eight terabytes of analyses, descriptions, and images of sediment and rock from the sea floor and lakebeds contributed by sources around the world are in the long-term archive. Examples of data available include sediment/rock composition, physical properties, petrology/mineralogy, geochemistry, paleontology, paleomagnetism, x-rays, and photographs of samples and the sea floor.
How to Contribute Data
Paleocean or paleolimnology geosample data may be contributed to NOAA Paleoclimatology. Sediment data from other environmental or habitat research may be contributed to the NOAA National Oceanographic Data Center. If you are an NGDC partner institution wishing to contribute data related to your sample repository holdings, more information is available on the Index to Marine and Lacustrine Geological Samples (IMLGS) page. For more information, or questions about contributing other marine geology data, please contact .
Access Marine Geology Data Archived by NGDC via External Websites
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.
