Field Activity Details for field activity 1991-019-FA

Other ID: 91-1

Status: Completed

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

Funding Program(s):

Location: Deep Water Dump Site DWDS 106, New Jersey Continental Slope, United States, North America, North Atlantic;

Principal Investigator(s): Michael Bothner

Affiliate Investigator(s): Fred Grassle - Rutgers Univ.

Information Specialist(s):

Data Type(s): Imagery: Video, Location-Elevation: Navigation, Location-Elevation: Transects

Scientific Purpose/Goals: Conduct a sidescan sonar survey for 48 hours. Collect samples and video of the sea floor using the robot JASON. The work will be conducted in the dump site and in a control area to the east. The sediment samples will be used for studies of benthic infauna, microbiology, heavy metal and organic geochemistry. The purpose of the sampling is to determine the distribution of the chemical enrichments from sewage sludge in the bottom sediments with distance from this dump site (located between 2,250-2,750 m water depth).
