USGS Coastal and Marine Geology Program

Field Activity Details for field activity 1983-002-FA

Other ID: AST 83-2

Status: Completed

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

Funding Program(s):

Principal Investigator(s): Robert N. Oldale

Affiliate Investigator(s): Ralph Lewis - CT DEP

Information Specialist(s):

Data Type(s): Location-Elevation: Navigation, Seismics: Boomer, Seismics: Sub Bottom Profiler, Sonar: Sidescan

Scientific Purpose/Goals: (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.

Vehicle(s):

Start Port/Location: Woods Hole, MA

End Port/Location: Woods Hole, MA

Start Date: 1983-05-23

End Date: 1983-06-04

Equipment Used: EG&G 234, Edo Western Sidescan and 2.5 kHz sub-bottom system, Loran-C, Single channel hydrophone

Information to be Derived: Sea floor map; Morphology;

Summary of Activity and Data Gathered: 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.
