Online_Linkage: https://doi.org/10.5066/F74B2ZGX Description: Abstract: Surveys of the bathymetry and backscatter intensity of the sea floor of the Historic Area Remediation Site (HARS), offshore of New York and New Jersey, were carried out in 1996, 1998, and 2000 using a Simrad EM1000 multibeam echosounder mounted on the Canadian Coast Guard ship Frederick G. Creed. The objective of the multiple echosounder surveys was to map the bathymetry and surficial sediments over time as dredged material was placed in the HARS to remediate contaminated sediments. Maps derived from the multibeam surveys show sea-floor bathymetry, shaded-relief bathymetry, and backscatter intensity (a measure of sea-floor texture and roughness) at a spatial resolution of 3 meters. The area was mapped by the U.S. Geological Survey in cooperation with the U.S. Army Corps of Engineers and with support from the Canadian Hydrographic Service and the University of New Brunswick. Purpose: The navigation polyline shapefile records the trackline followed by the Canadian Coast Guard ship Frederick G. Creed in the 1996 survey of the Historic Area Remediation Site. The tracklines can be used to identify line spacing, trackline orientation, and the location of data collection. The 1996 survey was carried out along tracklines running north-south and spaced about 100 m apart. The attributes record the latitude, longitude, date, and time at the start of each line. Supplemental_Information: These tracklines were not included with the original release of the HARS data. Maps and interpretations of these data are available in Butman and others (2002), Butman (2002), and Butman and others (2003) (citations in cross references). Other datasets from the 1996 HARS survey, as well as datasets from surveys of the HARS in 1998 and 2000, may be found in Butman and others (2017) (see larger work citation).

Completeness_Report: This shapefile contains edited tracklines for the 1996 multibeam survey of the Historic Area Remediation Site. Other datasets from the 1996 HARS survey 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. To qualitatively assess the horizontal accuracy of the three HARS surveys, the locations of 23 distinct features on the sea floor identified in the 1996, 1998, and 2000 shaded-relief images were compared. Offsets of features in the 1996 survey compared to the 1998 survey were typically 5 m or less, as expected when navigating with DGPS. Offsets of features in the 2000 survey compared to the 1998 survey were 10-20 m and to the north or south, the along-track direction of the survey. For 18 of the 23 features in the 2000 survey, offsets were to the north compared to the 1998 survey when the track in 2000 was to the south, and offsets were to the south compared to the 1998 survey when the track in 2000 was to the north. The offsets of the remaining 5 features, all surveyed on Julian Day 115, were in the direction of the survey track in 2000. The HARS surveys were run in a Zamboni pattern which resulted in blocks of adjacent survey lines running in the same direction; thus consistent offsets appear to shift these blocks north or south depending on the direction the lines were run. The cause of the offsets in the 2000 survey is unknown and no correction has been made for them.

Creed. The multibeam system utilizes 60 electronically-aimed receive beams spaced at intervals of 2.5 degrees that insonify a strip of sea floor up to 7.5 times the water depth. The horizontal resolution of the beam on the sea floor is approximately 10 % of the water depth. Vertical resolution is approximately 1 % of the water depth. Data were collected along tracklines spaced 5-7 times the water depth apart at a speed of 10-14 knots. The HARS was surveyed in a Zamboni pattern (for efficient turns at high speed) with lines running north-south. The Zamboni pattern yields blocks of southward-run lines adjacent to blocks of northward-run lines. The frequency of the sonar was 95 kHz. Sound velocity profiles were obtained and input into the Simrad processing system to correct for refraction. 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 1996-043-FA (https://cmgds.marine.usgs.gov/fan_info.php?fa=1996-043-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 larger work citation).
