USGS Coastal and Marine Geology Program

Field Activity Details for field activity 1981-016-FA

Other ID: NE-81-2

Status: Completed

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

Funding Program(s):

Principal Investigator(s): John Grow, Deborah Hutchinson

Affiliate Investigator(s):

Information Specialist(s):

Data Type(s): Electro-Magnetic: Magnetics, Location-Elevation: Navigation, Seismics: Multichannel, Sonar: Single Beam

Scientific Purpose/Goals: Determine whether the Connecticut Valley Triassic grabens extend south of New Haven into Long Island Sound. Determine whether sub-basement reflectors can be identified, especially in the vicinity of the gravity maximum which crosses western Long Island Sound and which is part of a major gravity anomaly extending from Georgia to Newfoundland.
