Summary for Field Activity Number 1975-011-FA

Alternate Leg ID: ASTR 75-JUN

Area of Operations: Rhode Island Sound, Rhode Island, Westport Harbor, Vineyard Sound, Cuttyhunk Island, Nomans Land, Martha's Vineyard, Massachusetts, United States, North America, North Atlantic

Dates: June 19, 1975 to June 30, 1975

Objectives: The cooperative program is designed to provide detailed geological information and an assessment of mineral resources pertaining to that part of the continental shelf beneath the coastal waters of Massachusetts. In anticipation of the development of offshore natural resources of the Commonwealth, the major focus of the research effort is directed toward the occurrance, nature and distribution of these deposits as well as establishment of baseline data for evaluation of environmental impact of exploitation. The sub-bottom profiling surveys provide the foundation for a planned program of vibracoring and bottom sampling of geological features. Laboratory analysis of the vibracore and bottom samples will evaluate the economic importance of the deposits and, coupled with the seismic data, provide information on the geology and geologic history of the area.

Type of Activity: Seismic profiling

Information to be derived: Sea floor map
Morphology

Summary: Traverses: 33 (27 in a NW-SE orientation with a line spacing of 1 nm, 6 in a SW-NE orientation with a line spacing of approximately 3 nm); Seismic data: 358 nm (663 km) and penetration of up to 125 meters below the bottom were achieved.
