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. Purpose: 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).
