Online_Linkage: https://doi.org/10.5066/F77H1GSF Description: Abstract: The Hudson Canyon begins on the outer continental shelf off the east coast of the United States at about 100-meters (m) water depth and extends offshore southeastward across the continental slope and rise. A multibeam survey was carried out in 2002 to map the bathymetry and backscatter intensity of the sea floor of the Hudson Canyon and adjacent slope and rise. The survey covered an area approximately 205 kilometers (km) in the offshore direction, extending from about 500 m to about 4,000 m water depth, and about 110 km in the alongshore direction, centered on the Hudson Canyon. The sea floor was mapped using a SeaBeam Instruments 2112 multibeam echosounder aboard the National Oceanic and Atmospheric Administration (NOAA) ship Ronald H. Brown. Maps derived from the multibeam observations show sea-floor bathymetry and backscatter intensity (a measure of sea floor texture and roughness), geomorphic provinces, and sea-floor environments (Butman and others, 2006). The sea floor was mapped by the U.S. Geological Survey in cooperation with Rutgers University and with support from NOAA. Purpose: The navigation shapefile shows the track followed by the NOAA ship Ronald H. Brown in the 2002 survey. The tracklines run northeast-southwest, approximately parallel to the slope bathymetry and perpendicular to the canyon axis. Supplemental_Information: Maps and interpretations of the multibeam echosounder data from the 2002 multibeam survey of the sea floor of the Hudson Canyon region are published in Butman and others (2006) (see cross reference). This publication includes the previously unpublished digital multibeam data and interpretations with FGDC-compliant metadata (CSDGM format). The data were collected on Woods Hole Coastal and Marine Science Center field activity 2002-050-FA (https://cmgds.marine.usgs.gov/fan_info.php?fan=2002-050-FA). Other datasets from the 2002 survey may be found in Butman and others (2017) (see larger work citation). Andrews and others (2013) (see cross reference) present a bathymetric terrain model for the Atlantic margin which includes the Hudson Canyon region.

Brown. This system utilized up to 151 electronically aimed beams spaced at intervals of 2 degrees that insonify a swath of sea floor up to 3 times the water depth. Over the continental rise, in water depths greater than about 2,000 m, a 5-km track separation was employed, which provided almost 100% overlap of the insonified area from swath to swath. Time considerations compelled less than ideal coverage of the continental slope area, where a track-line separation of about 1.7 km was used, that provided nearly no data overlap between swaths. The survey was conducted at approximately 10 knots (18.5 km/hr). The horizontal resolution of the beam on the sea floor ranged from about 20-65 m in the across-track direction and about 10 m in the along-track direction at 500 m water depth, and from about 100-400 m across-track and 40 m along-track at 3,000 m water depth. Navigation was by GPS. The data were collected on Woods Hole Coastal and Marine Science Center field activity 2002-050-FA (https://cmgds.marine.usgs.gov/fan_info.php?fan=2002-050-FA). Process_Step: Process_Description: A suite of processing software (called SwathEd) (Clarke, 1998; see cross reference) developed by the Ocean Mapping Group at the University of New Brunswick, Canada, was used to process, edit, grid, display, and archive the multibeam data. Navigation data were edited on-screen using the SwathEd routine jview to remove undesirable points, including turns at the ends of survey lines. Jview also rejects stray GPS fixes outside of the survey area, as set by the operator (see process steps for bathymetry available from the larger work citation).
