Field Activity 2002-050-FA

Identifier

2002-050-FA

Alternate names

Ron Brown HC02

Purpose

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

Location

Hudson Canyon, continental slope, continental rise, New York, New Jersey, New York Bight, mid-Atlantic Bight, United States, North America, North Atlantic;

Summary

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.

Comments

Processing required; attempt to minimize artifacts of poorly corrected ship-roll in bathymetry data. Seismic line info and navigation track not yet available. Contact Mary Scranton, SUNY, for station information. Original Center People field contained: James Robb (co-chief sci), Tammie Middleton (GIS). Original Submitted By field contained: Jim Robb, Brad Butman. Project = Hudson Canyon Mapping, Hudson Canyon Mapping
