Online_Linkage: https://doi.org/10.5066/F7C53J1Z Description: Abstract: The Hudson Shelf Valley is the submerged seaward extension of the ancestral Hudson River drainage system and is the largest physiographic feature on the Middle Atlantic continental shelf. The valley begins offshore of New York and New Jersey at about 30-meter (m) water depth, runs southerly and then southeasterly across the Continental Shelf, and terminates on the outer shelf at about 85-m water depth landward of the head of the Hudson Canyon. Portions of the 150-kilometer-long valley were surveyed in 1996, 1998, and 2000 using a Simrad EM1000 multibeam echosounder mounted on the Canadian Coast Guard ship Frederick G. Creed. The purpose of the multibeam echosounder surveys was to map the bathymetry and backscatter intensity of the sea floor of the valley, providing a framework for geologic, oceanographic, and geochemical studies. The data from the three surveys are combined to produce grids of bathymetry and backscatter intensity at 12-m resolution that cover the entire valley and the head of the Hudson Canyon. The mapping was done by the U.S. Geological Survey in cooperation with the U.S. Army Corps of Engineers with support from the Canadian Hydrographic Service and the University of New Brunswick. Purpose: The navigation polyline shapefile shows the track followed by the Canadian Coast Guard ship Frederick G. Creed in the 2000 survey of the Hudson Shelf Valley. The shapefile can be used to identify line spacing, trackline orientation, and the location of data collection. The attributes record the latitude, longitude, date, and time at the start of each line. The tracklines run approximately parallel to the axis of the valley. Supplemental_Information: Butman and others (1998), Butman and others (2003), and Thieler and others (2007) (see cross references) present maps and interpretations of the multibeam data. Other datasets from the survey of the Hudson Shelf Valley may be found in Butman and others (2017) (see larger work citation).

Edition 2.0 was created using revised processing software to correct a projection error in edition 1.0. The stretch for the images in edition 2.0 was also changed so that 255 is no data. Online_Linkage: https://doi.org/10.5066/F74B2ZGX Data_Quality_Information: Logical_Consistency_Report: All navigation data were processed in the same manner. The valley was surveyed in sections. Blocks of line numbers, in increments of 100, were assigned for each section. Completeness_Report: Shapefile includes all tracklines in the Hudson Shelf Valley surveyed in 2000. Other datasets from the survey of the Hudson Shelf Valley may be found in Butman and others (2017) (see larger work citation). Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: These data were navigated with a Differential Global Positioning System (DGPS) which is typically accurate to +/- 3 meters, horizontally. Repeated surveys of the Historic Area Remediation Site (HARS) (Butman and others, 2017), made on the same cruises and using the same instrumentation as the surveys of the Hudson Shelf Valley, were used to qualitatively assess the horizontal accuracy of the 1996, 1998, and 2000 surveys. The difference in location of sea floor features in the HARS identified in the 1996 and 1998 surveys were typically 5 m or less, as expected when navigating with DGPS. The difference in location of same features in the 1998 and 2000 survey were typically 10-20 m and in the along-track direction of the survey. This analysis suggests that the data collected in 1996 and 1998 surveys of the Hudson Shelf Valley are accurate to +/- 3 m horizontally, and the data collected in the 2000 survey accurate to 10-20 m horizontally.

Creed. The valley was surveyed with lines running approximately parallel to the valley axis; in some areas the lines were run in a Zamboni pattern for efficiency. The piecemeal survey pattern was a result of the limited endurance of the Creed, about 2 days, and weather. The frequency of the sonar is 95 kHz. Navigation was by means of differential GPS. Operation of the Simrad EM1000 was carried out by hydrographers of the Canadian Hydrographic Service. The data were collected on Woods Hole Coastal and Marine Science Center field activity 2000-015-FA (https://cmgds.marine.usgs.gov/fan_info.php?fa=1998-015-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 the multibeam and navigation 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 in link for larger work citation).
