USGS Coastal and Marine Geology Program

Coastal & Marine Geology Program

Field Activity Details for field activity 2002-032-FA

Other ID: OC384

Status: Completed

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

Funding Program(s):

Location: mid-Atlantic continental shelf, Hudson Canyon, New Jersey, Great South Channel, United States, North America, North Atlantic;

Principal Investigator(s): Page Valentine

Affiliate Investigator(s): Tom Noji/Vince Guida - NMFS, Sandy Hook, NJ

Information Specialist(s): Page Valentine

Data Type(s): Imagery: Photo, Sampling: Biology, Sampling: Geology

Scientific Purpose/Goals: Monitor the benthic habitat and fish productivity on the outer continental shelf adjacent to the Hudson Canyon, comparing areas of varying depth and varying degrees of disturbance by commercial trawling. Using underwater video and photographic techniques, characterize the topography of tilefish habitat for use in estimating tilefish and other fish populations and as a reconnaissance for submersible experiments with tilefish and other fisheries species, and characterize the state of disturbance along Great South Channel and adjacent Nantucket Lightship Closed Area.
