Area of Operations: northern Blake Plateau, United States, North America, North Atlantic

Dates: September 29, 1978 to October 19, 1978

Chief scientist: Pete Popenoe

Objectives: Assess types and frequencies of environmental hazards that may be encountered on the northern Blake Plateau; study the shallow geologic section to define these geologic hazards using high-resolution geophysical profiling gear on a 28-km grid; and test the shipboard gravity system to obtain gravity coverage of the northern Blake Plateau.

Type of Activity: Seismic profiling;

Information to be derived: Environmental hazards map

Summary: Airgun: 3570 km; Minisparker: 3487 km; 3.5 kHz: 3565 km.
