Status: Completed

Organization(s): USGS, Woods Hole Coastal and Marine Science Center

Information Specialist(s):

Data Type(s): Seismics: Sub Bottom Profiler, Sampling: Geology, Seismics: Air Gun / Water Gun, Seismics: Boomer, Seismics: Sparker, Electro-Magnetic: Magnetics, Sonar: Sidescan, 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) and seismic refraction (Leg 3 only) programs for regional geologic resource assessment studies will also be conducted.


Start Port/Location: Norfolk, VA

End Port/Location: Woods Hole, MA

Start Date: 1975-05-17

End Date: 1975-05-31

Equipment Used: 3.5 kHz, Air gun, Seismic Engineering streamer, Alpine Vibracorer, Magnavox satellite positioning system, Varian V-75 magnetometer, ORE sidescan, Raytheon 3.5 kHz sonar (CESP II) system, Del Norte 26 sparker, Loran-C

Information to be Derived:

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