Summary Information for Field Activity 1979-013-FA

Area of Operations: New England Atlantic outer continental shelf, United States, North America, North Atlantic

Dates: June 07, 1979 to June 25, 1979

Chief scientist: John Aaron

Objectives: 1. Determine location, extent, morphology, and internal geometry of mass sediment movement (slumps, slides) on the continental slope off New England using high-resolution geophysical methods (14.5 days). 2. Study and correlate stratigraphy of Jurassic and Cretaceous strata north and south of the New England sea mount chain using geophysical methods (3 days).

Type of Activity: Seismic profiling;

Information to be derived: Morphology;

Summary: Overall data quality is excellent, with good resolution and penetration. The data show much slumping on the continental slope between 500 and 2000 m water depth. Many displaced slump bodies occur near the base of the continental slope and on the upper continental rise. Slump study - 3.5 kHz/Minisparker/40 cu. in. airgun: 3257 km; Deep Stratigraphy - 3.5 kHz/Minisparker/500,160 cu. in. airguns: 775 km; Gravity: 4032 km; Magnetics: 4032 km.
