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.
