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): James M. Robb, John S. Schlee
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):
