Coastal & Marine Geology Program

Field Activity Details for field activity 1975-003-FA

Other ID: ATL2 89-2; 89, Leg 2

Status: Completed

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

Funding Program(s):

Principal Investigator(s): Robert N. Oldale

Affiliate Investigator(s):

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.

Vehicle(s):

Start Date: 1975-04-30

Start Port/Location: Woods Hole, MA

End Date: 1975-05-16

End Port/Location: Norfolk, VA

Equipment Used: 3.5 kHz, Alpine Vibracorer, Raytheon 3.5 kHz sonar (CESP II) system, Air gun, Seismic Engineering streamer, EG&G 234, Varian V-75 magnetometer, Magnavox satellite positioning system, Loran-C

Information to be Derived:

Summary of Activity and Data Gathered: Collected high-resolution seismic profiles (Uniboom) and airgun profiles on the shelf and slope between Virginia and Long Island.
