USGS Coastal and Marine Geology Program

Coastal & Marine Geology Program

Field Activity Details for field activity 1978-008-FA

Other ID: E-2E-78

Status: Completed

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

Funding Program(s):

Principal Investigator(s): Mark Ayers

Affiliate Investigator(s): Fred Keer - USGS

Information Specialist(s):

Data Type(s): Sampling: Biology, Sampling: Geology, Biological Field Study: Experiments, Seismics: Air Gun / Water Gun, Location-Elevation: Navigation

Scientific Purpose/Goals: Obtain at least 30 piston cores from 21 pre-selected target areas and determine character of bottom sediment in the study area. Subsamples were collected for hydrocarbon content, bacteria taxonomy, geotechnical properties, pore water geochemistry, and age determination.

Vehicle(s):

Start Port/Location: Brunswick, GA

End Date: 1978-04-13

End Port/Location: Beaufort, NC

Equipment Used: Dredge, Corer - slow, Corer - gravity, Air gun, Loran-C, Magnavox satellite positioning system

Information to be Derived: Samples and chemical analysis; Grain size analysis; Morphology;

Summary of Activity and Data Gathered: Piston cores: 51, archived at Duke; Box dredges: 26; Rock dredges: 12; Airgun.

Notes: Subsamples taken by David Schultz, USGS-Reston, for light hydrocarbon and organic anaylsis. Subsamples taken for Frank Senftle, Fred Sisler and Jody Zelibor, USGS-Reston, for bacterial and early diagenetic microbial degradation. Subsamples taken for Frank Manheim, USGS-Woods Hole, for geochemistry of interstitial pore water.
