Summary Information for Field Activity 1994-026-FA

Area of Operations: Cape Cod Bay, southern Stellwagen Basin, Massachusetts, United States, North America, North Atlantic

Dates: June 20, 1994 to June 29, 1994

Chief scientist: Harley Knebel
Rick Rendigs

Objectives: Sidescan sonar and 3.5 kHz survey (reconnaissance) and sediment sampling (if time permits).

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

Information to be derived: Grain size analysis; Habitat maps; Sea floor map; Bathymetric maps; Morphology;

Summary: Sidescan sonar: 445 km; 3.5 kHz Seismic: 445 km; Total 26 transects; No samples attempted. The cruise was very successful in accomplishing about 95 percent of the original expectations for total trackline coverage. Data quality was excellent and the records clearly displayed areas of high and low backscatter which will be useful for extending a sedimentary environments map southward from its present extent in Massachusetts Bay. The 3.5 kHz echo sounder was an excellent companion piece of equipment for detailing the shallow sub-bottom stratigraphy as the reflector's position relative to the surface of the sea floor is a useful adjunct for interpreting sidescan sonar records.
