Summary Information for Field Activity 1977-035-FA

Area of Operations: Nantucket Sound, Massachusetts, United States, North America, North Atlantic

Dates: September 27, 1977 to October 02, 1977

Chief scientist: Chuck O'Hara

Jim Katsolis - Eastern Instrument Corporation, Norwood, NJ

Objectives: The vibracore sampling program is intended to determine the nature of bottom sediments and shallow substrate on the inner shelf. The core data will be correlated with sub-bottom seismic profiling data to determine the distribution, lithology and economic significance of offshore geologic features and mineral resources. These studies will document important landmark data, help to evaluate feasibility and environmental impact of offshore mining of sand and gravel deposits and offshore disposal of solid waste material, and provide information on the geology and geologic history of the region.

Type of Activity: Vibracoring;vibracoring

Information to be derived: Samples and chemical analysis; Grain size analysis;

Summary: Vibracores: 20; Total feet penetrated: 459 (140 m); Total sediment recovered: 394 ft. (120 m); Percent Recovery: 86; Average core recovery per station: 19.7 ft. (6 m).
