Area of Operations: central and western Long Island Sound, Connecticut, New York, United States, North America, North Atlantic
Dates: May 18, 1985 to May 30, 1985
Chief scientist: Doug Owen
Ralph Lewis - CT DEP
Objectives: (1) Define the geology and shallow structure of westernmost Long Island Sound and selected areas in central Long Island Sound; (2) determine the geologic framework and Quaternary development of the area; and (3) identify and map potential geologic hazards.
Type of Activity: Seismic profiling
Seafloor mapping
Information to be derived: Sea Floor Map
Morphology
Summary: There were numerous equipment failures and problems during this cruise. However, overall the seismic records are satisfactory. Sidescan sonar was run primarily in the westernmost part of the Sound (a winch is needed in the future). The seismic records were mostly collected using the EG&G Uniboom system with the Benthos streamer. High-resolution seismic profiling: 662.5 km; Sidescan sonar: 404.3 km.
