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:
This shapefile shows an interpretation of geomorphic provinces (slope, base of slope depressions, canyon floor, canyon floor filled, canyon wall, upper rise, lower rise, rise valley) in the Hudson Canyon region based on multibeam bathymetry collected in 2002.
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 This publication includes the previously unpublished digital multibeam data and interpretations with FGDC-compliant metadata (CSDGM format).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.

Process_Step:
Process_Description:
Data gaps and overlaps between the hand-drawn polygons were removed using the following steps:
1) Shapefile was imported to a Feature Dataset (UTM 18) within a file geodatabase to build topology. (ArcMap v. 10.3.1) 2) Topology was created for each of the two feature classes (now in the Feature Dataset), with the topology rules "Must not overlap" and "Must not have gaps". Topology was then built and validated to identify those locations. 3) The topology and features were edited to remove/repair these topology errors. 4) Feature classes, were exported from the feature dataset back to shapefile using the geographic coordinate system.

Attribute_Domain_Values:
Enumerated_Domain:
Enumerated_Domain_Value: slope
Enumerated_Domain_Value_Definition:
The continental slope occupies the northwest portion of the study area and extends from the shoreward limit of the survey to water depths of 2,000-2,200 m. Areas that are not incised by submarine canyons exhibit slopes that range from 1.8-3 degrees in water depths shallower than 1,300 m and from 2.5-5 degrees in water depths deeper than 1,300 m.
Enumerated_Domain_Value_Definition_Source: USGS
Attribute_Domain_Values:
Enumerated_Domain:
Enumerated_Domain_Value: base of slope depressions
Enumerated_Domain_Value_Definition:
At the base of the continental slope there are a series of narrow, linear depressions. They are discontinuous, trend parallel to the base of the slope, are 0.5-2 km wide and 3-13 km long, and are as much as 23 m deeper than the surrounding sea floor.
Enumerated_Domain_Value_Definition_Source: USGS
Attribute_Domain_Values:
Enumerated_Domain:
Enumerated_Domain_Value: canyon floor
Enumerated_Domain_Value_Definition:
Canyon floors are the relatively flat axial valleys of submarine canyons. Most canyon floors have a comparatively high backscatter intensity on the backscatter image.
Enumerated_Domain_Value_Definition_Source: USGS
Attribute_Domain_Values:
Enumerated_Domain:
Enumerated_Domain_Value: canyon floor-filled
Enumerated_Domain_Value_Definition:
Shallow valleys located to the northeast of Hudson Canyon that can be traced from the mouths of the canyons at the base on the slope onto the upper rise where they coalesce into one valley that feeds into Hudson Canyon. These shallow valleys and two others on the northeastern side of Hudson Canyon are partially filled with mass-transport deposits.
Enumerated_Domain_Value_Definition_Source: USGS
Attribute_Domain_Values:
Enumerated_Domain:
Enumerated_Domain_Value: canyon wall
Enumerated_Domain_Value_Definition:
Canyon walls flank the axial valleys of submarine canyons. Where canyons transect the continental slope the average slope of the walls is about 8 degrees, the walls are eroded, and an intricate network of gullies indicates slope failure.
Enumerated_Domain_Value_Definition_Source: USGS
Attribute_Domain_Values:
Enumerated_Domain:
Enumerated_Domain_Value: upper rise
Enumerated_Domain_Value_Definition:
The upper continental rise lies seaward of the base-of-slope depressions and extends offshore to water depths of 3,000 – 3,100 m. The slope of the upper rise away from submarine canyons ranges from 0.2-0.9 degrees.
Enumerated_Domain_Value_Definition_Source: USGS
Attribute_Domain_Values:
Enumerated_Domain:
Enumerated_Domain_Value: lower rise
Enumerated_Domain_Value_Definition:
The lower continental rise extends from water depths of 3,000-3,100 m to beyond the southeastern edge of the study area. The slope of the lower rise ranges from 0.5-1.2 degrees and, on average, has a slightly greater slope than the upper rise.
Enumerated_Domain_Value_Definition_Source: USGS
Attribute_Domain_Values:
Enumerated_Domain:
Enumerated_Domain_Value: rise valley
Enumerated_Domain_Value_Definition:
Several linear valleys with bowl-like heads originate on the lower rise in water depths between 3,000 and 3,200 m water depth. The rise valleys are shallow, straight features with bowl-like heads that are 6-69 m deeper than the surrounding sea floor.
