Objectives: Contractor Western Geophysical Company of America will conduct a high-resolution geophysical survey on the upper continental slope in the Gulf of Mexico, north of latitude 26 N, in water depths between 100 m and 1,000 m with seismic lines spaced from 7.5 to 18.5 km apart in a reconnaissance grid pattern.

Type of Activity: Seismic profiling

Information to be derived: Morphology

Summary: The released data consist of single-channel geophysical records from a 3.5 kHz sub-bottom profiler and a 1,000 joule sparker operated simultaneously throughout 18,074 km of ship's track: Lines 1A, 2 thru 214, 20A, 22A, 26A, 30A, and 69A.
