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 0.00167. Longitudes are given to the nearest 0.00167. Latitude and longitude values are specified in Decimal degrees.
Alpha numeric code based on year, month, sample number
No gravel values recorded but mentioned in text (pg. 52) as found in water depths of 20 to 40 fathoms (36 to 73 meters), with pebbles over a centimeter in length.

"The purpose ... was (1) to describe the areal distribution of the sediments and their compositional and textural variations, and (2) to use these variations as indiators of sedimentary processes on the continental shelf."

Data sources produced in this process:
No estimate made for the accuracy of the data in the original report. Data digitized by the USGS and partners were visually compared to the source data, and corrected. Where appropriate, data were tested for completeness using MS Excel. Locations checked using GIS.
No navigational techniques given in report. Positions given to minute-tenths.
Depth determination technique not given in report. Water depths recorded to nearest fathom.
Locations and depths from appendix 1; textural parameters and statistics from appendix 2; Glauconite in sand percentages from appendix 3; Percent heavy minerals in sand fraction of selected samples; Heavy mineral counts of selected samples from appendix 5 were digitized, except those samples which are originally from Bushnell, 1963 (Runge samples 252-273) and Maloney, 1965 (Runge samples 374-477 and 482-495), which are in usSEABED under those sources.
Data fall within normal ranges for the given parameters.
Are there legal restrictions on access or use of the data?

Although this dataset has been used by the USGS, no warranty, expressed or implied, is made by the USGS as to the accuracy of the data. Users of the data should be aware of limitations of the data due to possible imprecision due to navigational inaccuracies and limitations of the statistical data.
