  Description:
    Abstract: This GIS overlay is a component of the U.S Geological Survey, Woods Hole Science Center's, Gulf of Mexico GIS database.  The Gulf of Mexico GIS database is intended to organize and display USGS held data and provide on-line (WWW) access to the data and/or metadata.
    Purpose: 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).

      Source_Contribution: Gas hydrate stability zone contours - This CD-ROM contains files in support of the 1995 USGS National assessment of United States oil and gas resources (DDS-30), which was published separately and summarizes the results of a 3-year study of the oil and gas resources of the onshore and state waters of the United States. The study describes about 560 oil and gas plays in the United States; confirmed and hypothetical, conventional and unconventional. A parallel study of the Federal offshore is being conducted by the U.S. Minerals Management Service. This CD-ROM contains files in multiple formats, so that almost any computer user can import them into word processors and spreadsheets. The tabular data include some tables not released in DDS-30. No proprietary data are released on this CD-ROM, but some tables of summary statistics from the proprietary files are provided. The complete text of DDS-30 is also available, as well as many figures. Also included are some of the programs used in the assessment, in source code and with supporting documentation. A companion CD-ROM (DDS-35) includes the map data and the same text data, but none of the tabular data or assessment programs.

    Process_Step:
      Process_Description: This file was read into ArcView 3.2 using an avenue script called loalin.ave which converted the ungenerate format to a shapefile.  The file was made into a polyline shapefile, and the projection was kept as the original Albers Equal Area.
    Process_Step:
      Process_Description: ArcToolbox was used to define the projection of the shapefile as Albers Equal Area, NAD83.  The projection information used was listed by ESRI as: USA_Contiguous_Albers_Equal_Area_Conic_USGS.
    Process_Step:
      Process_Description: The shapefile was then reprojected to Geographic, NAD83 using ArcToolbox, v. 8.2.
