Since 1982 the U.S. Geological Survey (USGS) has collected a large amount of surficial and shallow subsurface geologic information in the deep parts of the Gulf of Mexico. These data include digital sidescan sonar imagery, digital seismic-reflection data, and descriptions and analyses of piston and gravity cores. The data were collected during several different projects that addressed surficial and shallow subsurface geologic processes. Some of these data sets have already been published, but the growing interest in the occurrence and distribution of gas hydrates in the Gulf of Mexico warrants integrating these existing data and associated interpretations into a GIS to provide regional background information for ongoing and future gas hydrate research.
This GIS data layer shows the geomorphic provinces of the deep-water part of the Gulf of Mexico. The interpretation draws on the geologic interpretation (EEZ-SCAN Scientific Staff, 1987; Paskevich, 2000) and publications by Twichell and others (1990; 1991; 2000).

The interpretive overlay, morphology.shp, used the gloria.tif image and the geology.shp shapefile as a base, and then incorporated the morphology of different parts of the Gulf of Mexico that has been described in studies by EEZ-Scan 85 Scientific Staff (1987), Paskevich (2000, and Twichell and others (1990, 1991, 2000). The components of the interpretation and their sources are listed below: Salt deformed slope - modified from Paskevich (2000) Basin floor - combined sediment wave and hemipelagic drape of Paskevich (2000) Mesozoic/Cenozoic carbonate - taken from Paskevich (2000) and Twichell and others (1990) Carbonate slope - same as Pleistocene carbonate mud of Paskevich (2000) Sigsbee Escarpment - same as Paskevich (2000) Seamount - same as Paskevich (2000) Mississippi Fan - from Twichell and others (1991) Bryant Fan - from Twichell and others (2000). Processing took place after 2001.

Edits to the metadata were made to fix any errors that MP v 2.9.36 flagged. This is necessary to enable the metadata to be successfully harvested for various data catalogs. In some cases, this meant adding text "Information unavailable" or "Information unavailable from original metadata" for those required fields that were left blank. Other minor edits were probably performed (title, publisher, publication place, etc.). Attempted to modify http to https where appropriate. The link to the larger work citation had to be fixed. Added an online link to a cross-reference. Fixed some of the cross-reference citations. The source information was incomplete and had to be modified to meet the standard. The metadata date (but not the metadata creator) was edited to reflect the date of these changes. The metadata available from a harvester may supersede metadata bundled within a download file. Compare the metadata dates to determine which metadata file is most recent.
