The file was begun by NGDC in 1976 in response to a need by the Outer Continental Shelf Environmental Assessment Program (OCSEAP) for a detailed, digital file of textural analyses. Data are from OCSEAP studies, academic institutions, environmental baseline studies conducted under contract to the Bureau of Land Management under the Outer Continental Shelf (OCS) Program, and from laboratory reports generated by the U.S. Naval Oceanographic Office. Data include collecting institution, ship, cruise, sample id, latitude/longitude, date of collection, water depth, sampling device, method of analysis, sample weight, sampled interval, raw weight percentages of sediment, within a given phi range. Some samples also have percentages of total gravel, sand, silt, clay, and statistical measurements such as mean, median, skewness, kurtosis, and standard deviation of grain size. environmental research US Department of Commerce, National Oceanic and Atmospheric Administration (NOAA), NOAA Satellite and Information Service (NESDIS), National Centers for Environmental Information (NCEI), and World Data Service for Geophysics, Boulder. completed historicalArchive NOAA National Centers for Environmental Information ncei.info@noaa.gov https://www.ncei.noaa.gov/contact NCEI Contact Information Information for contacts at NCEI. information pointOfContact NOAA National Centers for Environmental Information Marine Geology Data Manager 325 Broadway, Mail Code E/NE42 Boulder CO 80305-3328 USA geology.info@noaa.gov pointOfContact notPlanned Although no updates are planned, project-specific updates are possible if resources become available. https://www.ngdc.noaa.gov/mgg/image/placer.jpg image of a placer deposit JPEG OCS > Outer Continental Shelf Program OCSEAP > Outer Continental Shelf Environmental Assessment Project ICSU-WDS > International Council for Science - World Data System project Global Change Master Directory (GCMD) Project Keywords 2020-01-09 publication 9.1 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2024.

Reliability Quality control: Missing data or gross percentage errors are noted. Processing: Data sources include contractors for the Outer Continental Shelf Environmental Assessment Program; contractors for the Outer Continental Shelf Office, Bureau of Land Management; and project managers from academic institutions. Lineage varies by data source. Most data were contributed originally to NOAA's former National Oceanographic Data Center (NODC) as part of larger environmental studies. NODC forwarded the grain size portion of these studies to NGDC for distribution and archive, and in many cases maintained a copy for the NODC archive. Relatively few data sets were contributed directly to the former National Geophysical Data Center (NGDC). Some data were coded by NGDC from paper reports, especially unpublished laboratory item reports from the U.S. Naval Oceanographic Office (NAVOCEANO). Some data were translated from other formats, including the historic 003 Intergovernmental Oceanographic Commission (IOC) format, and the University of Washington format. Last data processed into database 2000-12-31T00:00:00 multiple investigators, institutions, and funding sources, many under contracts of the Bureau of Land Management Outer Continental Shelf Program (BLM/OCS) or Outer Continental Shelf Environmental Assessment Program (OCSEAP).
