USGS Coastal and Marine Geology Program

Coastal & Marine Geology Program

Field Activity Details for field activity 1985-016-FA

Other ID: AST 85-8

Status: Completed

Organization(s): USGS, Woods Hole Coastal and Marine Science Center

Funding Program(s):

Location: central and western Long Island Sound, Connecticut, New York, United States, North America, North Atlantic;

Principal Investigator(s): Douglass Owen

Affiliate Investigator(s): Ralph Lewis - CT DEP

Information Specialist(s):

Data Type(s): Seismics: Boomer, Sonar: Sidescan, Seismics: Air Gun / Water Gun, Seismics: Bubble Gun, Seismics: Sparker, Location-Elevation: Navigation

Scientific Purpose/Goals: (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.


Start Date: 1985-05-18

Start Port/Location: Block Island, RI

End Date: 1985-05-30

End Port/Location: Woods Hole, MA

Equipment Used: EG&G 234, ORE GeoPulse, Klein 531 sidescan, Innerspace Technology 25-element hydrophone, Loran-C

Information to be Derived: Sea floor map; Morphology;

Summary of Activity and Data Gathered: 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.
