NCEI Marine Geology Data Archive

Metadata Updated: November 12, 2020

Marine Geologic data compilations and reports in the NCEI archive are from academic and government sources around the world. Over ten terabytes of analyses, descriptions, and images of sediment and rock from the ocean floor and lakebeds are available. Examples of data available include sediment/rock composition, physical properties, petrology/mineralogy, geochemistry, paleontology, paleomagnetism, x-rays, photographs, and other imagery. All reports and data, regardless of format, are accessible via the Marine Geology Digital Inventory and/or linked to the Index to Marine and Lacustrine Geological Samples (IMLGS). Searches offer free, immediate download of digital data, many images, and .PDF reports, and information on how to obtain full-resolution images from the archive, and order CD-ROMs, microfilm, or oversize charts. Some larger data sets, including the IMLGS, have their own web interfaces. The IMLGS provides searches of sea floor and lakebed cores, grabs, dredges, and drill samples available from sample repositories at partner institutions, with links to browse and download related information from NCEI and other sources.
