Other ID: ANN-2-77
Organization(s): USGS, Woods Hole Coastal and Marine Science Center
Location: Nantucket Sound, Massachusetts, United States, North America, North Atlantic;
Principal Investigator(s): Charles J. O'Hara
Affiliate Investigator(s): Jim Katsolis - Eastern Instrument Corporation, Norwood, NJ
Data Type(s): Sampling: Geology, Location-Elevation: Navigation
Scientific Purpose/Goals: 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.
