Summary for Field Activity Number 1975-006-FA

Alternate Leg ID: ATL2 89-3; 89, Leg 3

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

Dates: May 17, 1975 to May 31, 1975

Objectives: Conduct a geology and geophysics cruise along the Atlantic continental margin between Virginia and Cape Cod, concentrating on the continental shelf and slope between Virginia and Long Island where high-resolution seismic reflection profiling, vibracoring and bottom samples are needed for Bureau of Land Management (BLM) and USGS environmental impact studies in areas where petroleum lease sales are being considered. Single-channel seismic reflection profiles (airgun), gravity, and magnetics (Legs 1-3) and seismic refraction (Leg 3 only) programs for regional geologic resource assessment studies will also be conducted.

Type of Activity: Gravity and magnetics

Information to be derived: Morphology

Summary: Collected seismic reflection profiles, plus three seismic refraction lines along the outer shelf and continental slope off New Jersey.

USGS Project Number: RA-EA
