Alternate Leg ID: W-39, Leg 4
Area of Operations: South Carolina, Southern New England Continental Shelf, Mud Patch, United States, North America, North Atlantic
Dates: May 14, 1978 to May 24, 1978
Objectives: USGS cruise (4 days) piggybacked on SEA cruise to conduct sidescan sonar and high-resolution seismic reflection surveys of a west-east transect across the South Carolina shelf off Charleston and a more extensive survey of the Mud Patch on the southern New England shelf.
Type of Activity: Seismic profiling
Sea floor mapping
Information to be derived: Sea floor map
Summary: No clear sub-bottom reflectors were noted in the entire survey of the southern New England shelf. In part this reflects limitations of the profiling equipment although better records might have been obtained at slower speeds with greater submergence of the transducer. Sidescan sonar: 368 km; Sub-bottom profiles: 368 km.
