Status: Completed

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

Funding Program(s):

Principal Investigator(s): Bradford Butman, James M. Robb

Affiliate Investigator(s): Peter Rona (Rutgers University)

Information Specialist(s): James M. Robb

Data Type(s): Sonar: Multibeam, Seismics: Sub Bottom Profiler, Environmental Data: CTD, Sampling: Chemistry, Location-Elevation: Navigation

Scientific Purpose/Goals: Bathymetric mapping of the continental slope and rise areas adjacent to Hudson Canyon using multibeam echo-sounding and 3.5 kHz profiling.

Vehicle(s):

Start Port/Location: Miami, FL

End Port/Location: New York, NY

Start Date: 2002-08-27

End Date: 2002-09-15

Equipment Used: SeaBeam 2112, ODEC 3.5 kHz, CTD 19+ with OBS, PAR, DO, Chl, Niskin bottle, GPS (wh)

Information to be Derived:

Summary of Activity and Data Gathered: 60x110 nmi (111x204 km) bathymetric map; water depths and backscatter recorded by Seabeam system; ODEC 3.5 kHz profile digital data along ~2600 nmi (~4815 km) of track.

Staff: James M. Robb, Tammie Middleton
