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 0.000000. Longitudes are given to the nearest 0.000000. Latitude and longitude values are specified in Decimal degrees.
The horizontal datum used is North American Datum of 1983.
The ellipsoid used is Geodetic Reference System 80.
The semi-major axis of the ellipsoid used is 6378137.000000.
The flattening of the ellipsoid used is 1/298.257222.
Sequential unique whole numbers that are automatically generated.

This GIS data layer shows the calculated thickness of the gas hydrate stability zone in meters within the U.S. Exclusive Economic Zone for the Gulf of Mexico and Atlantic Ocean regions. The contour lines were compiled by Collett (1995) as part of the assessment of gas hydrate resources for the 1995 National assessment of United States oil and gas resources. The tabular data used to generate this shapefile were copied from Charpentier et al (1996).
