This is a Vector data set. It contains the following vector data types (SDTS terminology):
Horizontal positions are specified in geographic coordinates, that is, latitude and longitude. Latitudes are given to the nearest 0.000001. Longitudes are given to the nearest 0.000001. Latitude and longitude values are specified in Decimal degrees.
The horizontal datum used is North American Datum of 1927.
The ellipsoid used is Clarke 1866.
The semi-major axis of the ellipsoid used is 6378206.400000.
The flattening of the ellipsoid used is 1/294.978698.
Sequential unique whole numbers that are automatically generated.
Coordinates defining the features.

The purpose of this report is to describe the field methods used to collect marine sediment samples and the laboratory methods used to determine and characterize the grain-size distributions, to present these data in several flat-file formats that can be readily employed by interested parties, and to provide referenceable verified data and metadata to an Access relational database being developed as part of the USGS Coastal and Marine Geology Program’s Aggregates Project.

Those samples from the USGS's Woods Hole Science Center labs (coded with a "3") were imported into usSEABED. Those coded with "1" and "2" represent the ConMar data and are included elsewhere. In the original report, all samples were given as individual analyses with attached database IDs (DB_IDs), with no effort made to group subsamples from the same core together. Here, these samples are grouped together, and downcore analyses are included under the topmost sample's DB_ID, given in brackets in the sitename. Subsample DB_IDs are included as metadata in the input data resource file. Data are listed in order of the topmost sample's DB_IDs. SEDCLASS classification are included as Shepard classification for all samples with textural analyses (input field LTH:30). For those samples without textural analyses (mostly boulders, n = 89), the SEDCLASS description are included in input field LTH:8 for parsing by the dbSEABED software.
