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.
This shapefile shows sea-floor environments (failed slope, mass-transport deposits, buried mass-transport deposits, sediment waves, eroded strata, and hemipelagic sediments) in the Hudson Canyon region based on backscatter intensity, physiography, and sub-bottom characteristics.
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 This publication includes the previously unpublished digital multibeam data and interpretations with FGDC-compliant metadata (CSDGM format).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.

Interpretations were based on bathymetry and backscatter intensity data from the Ronald H. Brown multibeam survey and high-resolution seismic profiling data in USGS Woods Hole Coastal and Marine Science Center archives (EEZ Scan Scientific Staff, 1991; see cross reference). Data gaps and overlaps were identified and corrected.
Bathymetry and backscatter intensity data from the 2002 Ronald H. Brown multibeam survey (field activity 2002-050-FA; https://cmgds.marine.usgs.gov/fan_info.php?fan=2002-050-FA) and selected high-resolution profiling data in the USGS Woods Hole Coastal and Marine Science Center archives (EEZ Scan Scientific Staff, 1991; see cross reference) were used to make this interpretation of sea-floor environments in the Hudson Canyon region. See Butman and others (2006) (in cross references).
Accuracy of hand-drawn interpreted layer estimated to be several pixels (200 - 600 m) depending on water depth).
Geologic facies (eroded strata, failed slope, hemipelagic sediments, mass-transport deposits, buried mass-transport deposits, sediment waves) were identified using multibeam and high-resolution seismic data (Butman and others, 2006; EEZ-Scan Scientific Staff, 1991). Outlines of each facies were drawn by hand and converted to a shapefile.

Data gaps and overlaps between the hand-drawn polygons were removed using the following steps:
1) Polygon shapefile with six individual interpreted layers was imported to a Feature Dataset (UTM 18) within a file geodatabase to build topology. (ArcMap 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.

INTERP
Interpretation of sea-floor environments (geologic facies) of the Hudson Canyon region based on multibeam bathymetry and backscatter intensity data, and high-resolution seismic profiles.
USGS
failed slope
Areas of the sea floor on the continental slope that have an extensive but subtle network of scarps revealed in the multibeam bathymetry. Most of the scarps, which are attributed to mass wasting, are 20-75 m high. High-resolution seismic profiles show that the scarps truncate reflectors that underlie the stable parts of the slope to either side of the failed areas. The sea floor below the scarps is rough and commonly interrupted by additional scarps.
USGS
hemipelagic
Hemipelagic deposit. Areas of the sea floor away from submarine canyons, primarily on the continental rise, identified by a smooth sea floor with low backscatter intensity, and where subbottom profiles show closely-spaced reflections that parallel the sea floor. On the continental slope, hemipelagic sediment occupies the inter-canyon sections of the upper slope and covers less of the lower part of the slope.
USGS
mtd
Mass-transport deposits (mtd) in an area southwest of Hudson Canyon are identified by long narrow 'fingers' of high backscatter intensity material that originate near the base of the slope and extend downslope as much as 120 km to the south in shallow depressions. Mass-transport deposits northeast of Hudson Canyon are identified by areas of moderate to high backscatter intensity that begin at the base of the continental slope and cover most of the upper rise. High-resolution seismic profiles show that this area is characterized by seismically transparent layers and a rough surface.
USGS
mtd_buried
seaward portions of two fingers of mass-transport deposits (mtd) on the continental rise southwest of Hudson Canyon covered by sediment waves.
USGS
eroded strata
Areas of the sea floor along the canyon axis that appear nearly flat in the shaded relief image and floored with material showing high backscatter intensity, and areas on the canyon walls with an intricate network of gullies that indicate slope failure.
USGS
sediment waves
A field of sediment waves lies on the upper continental rise on the southwest side of Hudson Canyon, and is shown most clearly on the image of backscatter intensity. The waves begin about 25 km seaward from the base of the continental slope and extend southward about 80 km across the upper rise. The sediment waves abut the rim of Hudson Canyon for approximately 50 km. These waves have crests oriented roughly east-west and wavelengths of 900-1,500 m.

This shapefile shows sea-floor environments (geologic facies) of the Hudson Canyon and adjacent slope and rise interpreted using the multibeam bathymetry and backscatter intensity data, and selected high resolution seismic profiles in the USGS archives. The geologic facies are: failed slope, mass-transport deposits, buried mass-transport deposits, sediment waves, eroded strata, and hemipelagic sediments. The province (slope or rise) identifies the location of the various facies.
