Field Activity Details for field activity 1987-008-FA

Other ID: FRNL 87-2; Leg 2

Status: Completed

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

Funding Program(s):

Principal Investigator(s): John S. Schlee, James M. Robb

Affiliate Investigator(s):

Information Specialist(s): Nancy K. Soderberg

Data Type(s): Sonar: Sidescan, Seismics: Sub Bottom Profiler, Seismics: Air Gun / Water Gun, Seismics: Boomer, Seismics: Bubble Gun, Seismics: Sparker, Environmental Data: Temperature, Location-Elevation: Navigation, Electro-Magnetic: Magnetics

Scientific Purpose/Goals: GLORIA (long-range sidescan sonar) mapping of East Coast U.S. mid-Atlantic region via contract with IOS (Institute of Oceanographic Sciences, United Kingdom). This was Leg 2 of a 5-leg effort to map the East Coast U.S. Exclusive Economic Zone (EEZ). Part of the cruise time was spent recovering area designated for Leg 1 but not surveyed due to weather. In turn, some of the Leg 2 area was not covered. Unsurveyed parts will probably be covered during Leg 4.

Vehicle(s):

Start Date: 1987-03-01

Start Port/Location: Norfolk, VA

End Date: 1987-03-26

End Port/Location: Woods Hole, MA

Equipment Used: GLORIA sidescan, 3.5 kHz, Air gun, Geomechanique streamer, XBT, ABC navigation system, Geometrics G-856 magnetometer, Northstar 6000 LORAN-C, Megapulse Accufix 500 LORAN-C

Information to be Derived: Sea floor map; Morphology;

Summary of Activity and Data Gathered: GLORIA sidescan sonar: 6100 km; Airgun: 6100 km; 3.5 kHz: 6100 km; 10 kHz: 6100 km; XBT: 20 (47 tries); Magnetics: 6100 km.
