Alternate Leg ID: 94-3
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: Richard Rendigs - Chief Sci, Harley Knebel - Data Analysis
Objectives: Sidescan sonar and 3.5 kHz survey (reconnaissance) and sediment sampling (if time permits)
Type of Activity: Seismic profiling
Seafloor 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 echosounder was an excellent companion piece of equipment for detailing the shallow subbottom stratigraphy as the reflectors position relative to the surface of the seafloor is a useful adjunct for interpreting sidescan sonar records.
