Principal Investigator(s): James M. Robb, Peter Popenoe
Affiliate Investigator(s): Derek Bishop - IOS
Information Specialist(s): Nancy K. Soderberg
Data Type(s): Sonar: Sidescan, Seismics: Air Gun / Water Gun, Seismics: Boomer, Seismics: Bubble Gun, Seismics: Sparker, Seismics: Sub Bottom Profiler, Sonar: Single Beam, 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, U.K.). This was a gap-filling period to adjust for time lost and survey area not covered because of bad weather during Legs 1 and 2 of the effort to map the East Coast U.S. Exclusive Economic Zone (EEZ).
