Coastal & Marine Geology Program

Field Activity Details for field activity 1978-024-FA

Other ID: 78-G7; 78-G-7

Status: Completed

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

Funding Program(s):

Location: Georges Bank, Mud Patch, Middle Atlantic Outer Continental Shelf, Massachusetts, New Jersey, United States, North America, North Atlantic;

Principal Investigator(s): Michael Bothner

Affiliate Investigator(s):

Information Specialist(s): Richard Rendigs

Data Type(s): Environmental Data: CTD, Environmental Data: Turbidity, Location-Elevation: Navigation, Sampling: Chemistry, Sampling: Geology, Seismics: Sub Bottom Profiler, Time Series: Mooring (physical oceanography)

Scientific Purpose/Goals: Collect hydrographic and suspended matter data on Georges Bank and continental shelf areas off the New England and Middle Atlantic States. This is an ongoing study to determine the seasonal distribution and composition of suspended matter along the eastern seaboard. Additional cruise objectives were the deployment and recovery of three moorings with attached current meters and sediment traps. Sediment samples were collected at three locations with a grab sampler and with a hydrostatically damped gravity corer.
