Summary Information for Field Activity 1987-015-FA

Area of Operations: Hatteras Canyon, North Carolina continental slope and rise, United States EEZ, North America, North Atlantic

Dates: April 27, 1987 to May 08, 1987

Chief scientist: Pete Popenoe
Jim Robb

   Derek Bishop - IOS

Objectives: 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).

Type of Activity: Seismic profiling; Sea floor mapping;Sea floor mapping

Information to be derived: Sea floor map; Morphology;

Summary: GLORIA sidescan sonar; Airgun: 3240 km; 3.5 kHz: 3240 km; 10 kHz soundings: 19 XBT profiles; Magnetics: 3240 km.
