Other ID: ATL2 89-2; 89, Leg 2
Organization(s): USGS, Woods Hole Coastal and Marine Science Center
Location: Atlantic outer continental shelf, United States, North America, North Atlantic;
Principal Investigator(s): Robert N. Oldale
Information Specialist(s): Nancy K. Soderberg
Data Type(s): Seismics: Sub Bottom Profiler, Sampling: Geology, Seismics: Air Gun / Water Gun, Seismics: Boomer, Seismics: Sparker, Electro-Magnetic: Magnetics, Location-Elevation: Navigation
Scientific Purpose/Goals: 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) programs for regional geologic resource assessment studies will also be conducted.
