        <gco:CharacterString>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.</gco:CharacterString>

        <gco:CharacterString>Marine geology data in the NCEI archive are from diverse projects and programs, and were funded by many sources around the world, for example the National Science Foundation (NSF). Please cite the original source when using these data. Many of the core and seabed photographs and descriptions in the archive 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.</gco:CharacterString>
