Other ID: NEE-80-1

Status: Completed

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

Funding Program(s):

Principal Investigator(s): Charles J. O'Hara

Affiliate Investigator(s):

Information Specialist(s):

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

Scientific Purpose/Goals: Define geology and shallow structure of western Rhode Island Sound. Identify and map potential geologic hazards. Determine geologic framework and Quaternary development of this part of Atlantic Inner Continental Shelf. Select sites for possible coring during summer 1981. Complement similar data and findings of this office in eastern Rhode Island Sound.
