      Other_Citation_Details: These data represent digitized data from paper data sheets from the National Ocean Service (NOS) archived at the Smithsonian Institution. In 2001, the digital data were archived at NOAA's National Geophysical Data Center.  The data as used in usSEABED are from NGDC in 2001.
  Description:
    Abstract: As unpublished data, there is no abstracted information.
    Purpose: The data were collected during dozens of cruises by the National Ocean Service to investigate the sediment type and water depths of areas of interest in United States waters.
    Supplemental_Information: In 2004,the data were migrated to another format file at the Smithsonian Institution.

Data_Quality_Information:
  Attribute_Accuracy:
    Attribute_Accuracy_Report: Statistical data was digitized by hand at the Smithsonian Institution.  At the USGS, the data were viewed in a GIS to determine samples with unlikely locations.  In addition, at the University of Colorado, data were passed through a velocity filter to identify samples with notable distances between sequential data points; these samples were tagged.  Each tagged sample was manually corrected as possible by comparing the degree and/or minute of location to those within the same cruise ID and day; this affected about 700 samples.  Approximately 4300 samples have no location, nonspecific location information, or unresolvable inconsistent locations. These data are not included in the outputs of usSEABED.  Where appropriate, data were tested for completeness using MS Excel.
  Logical_Consistency_Report: Some data do not pass the location test.
  Completeness_Report: Data are incomplete, as some are missing sampler information and probably not all data have been digitized by the Smithsonian.
  Positional_Accuracy:
    Horizontal_Positional_Accuracy:
      Horizontal_Positional_Accuracy_Report: Navigational techniques not recorded in report; latitudes and longitudes given in degrees, minutes, seconds.
    Vertical_Positional_Accuracy:
      Vertical_Positional_Accuracy_Report: Water depth determination technique not noted in report.  Water depths given in meters.
