Summary Information for Field Activity 1976-011-FA

Area of Operations: outer continental shelf, Texas, Louisiana, Mississippi, United States, Gulf of Mexico, North America, North Atlantic

Dates: April 18, 1976 to May 05, 1976

Chief scientist: Gary Hill

Objectives: General objective of the Gulf of Mexico Continental Slope project is to define the possible extent of unstable sediments on the slope and estimate the degree of instability in selected areas. The first phase of the slope project involved acquisition and interpretation of 11,233 statute miles of high-resolution seismic data throughout the study area. Western Geophysical Company of America collected the geophysical data incuding fathometer profiles, 3.5 kHz sub-bottom profiles and 1000 joule sparker profiles. From these data, a map of the shallow surface geological features of the slope was produced. Using this information, specific sites were chosen for deep gulf cruises aboard the FAY. High density seismic profiling was done at each site followed by a sediment sampling program.

Type of Activity: Sampling; Seismic profiling; Photography;

Information to be derived: Sea floor map; Morphology;

Summary: Minisparker profiles: 1579 km; 3.5 kHz EDO profiles: 398 km; Piston cores: 17; Hydroplastic cores: 16; Smith-MacIntyre samples: 20; Core logs: 39A, B, C; Bottom photo stations: 17; Oxygen traces: 0; Gravity cores: 0.
