The NGDC (now NCEI) Seafloor Sediment Grain Size Database contains particle size data for over 17,000 seafloor samples worldwide. 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.

Horizontal Positional Accuracy
The horizontal accuracy of data values is approximately .001 degree of latitude/longitude.
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 Some data were coded by NGDC from paper reports, especially unpublished laboratory item reports from the U.S. Naval Oceanographic Office (NAVOCEANO).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.
