Area of Operations: central Long Island Sound, Clinton to New Haven, Connecticut, United States, North America, North Atlantic
Dates: May 23, 1983 to June 04, 1983
Objectives: (1) Define geology and shallow structure of central Long Island Sound; (2) determine geologic framework and Quaternary development of the study area; and (3) identify and map potential geologic hazards.
Type of Activity: Seismic profiling
Information to be derived: Sea floor map
Summary: Uniboom data were very good (excellent penetration and good resolution) except in areas where the acoustic signal was attenuated by gas in the sediments. Sidescan sonar records were satisfactory. Uniboom: 656 km; Sidescan sonar: 422 km.
