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 GeoTIFF image of shaded-relief bathymetry colored by backscatter intensity provides a visualization of both bathymetry and backscatter intensity. The shaded-relief image was created by vertically exaggerating the bathymetry 4 times and then artificially illuminating the relief by a light source positioned 45 degrees above the horizon from the north. The illumination from the north, approximately parallel to the survey lines, minimizes artifacts caused by small depth changes that may occur between lines. The backscatter intensity is represented by a suite of eight colors ranging from blue (low intensity) to green to yellow to red (high intensity).
Supplemental_Information:
This is Edition 2.0 of GeoTIFF Hars1998Pseudo.tif. An error in the University of New Brunswick (Clarke, 1998, see cross reference) processing software that resulted in the multibeam observations not being properly projected onto a plane was discovered in 2003. A second error in the gridding algorithm was discovered in 2007, requiring a shift of 1/2 grid cell to northwest. Edition 2.0 differs from Edition 1.0 (Butman and others, 2002) in that it was processed using corrected software; comparison of the location of selected features suggests that Edition 2.0 is shifted approximately 10 m to the east compared to Edition 1.0. In addition, the stretch used to create the 8-bit image is 0-254 and the value 255 is no data. In Edition 1.0, the stretch is 0-255 and the value 255 is also no 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).

Data_Quality_Information:
Logical_Consistency_Report:
All data were processed in the same manner. Some features in the multibeam data are artifacts of data collection and environmental conditions. They include small highs and lows and unnatural-looking features, and patterns oriented parallel or perpendicular to survey tracklines. The orientation of the tracklines is sometimes identified by the faint parallel stripes in the image.
Completeness_Report:
This image contains all bathymetry and backscatter intensity data collected in the Historic Area Remediation Site on WHCMSC field activity 1998-015-FA. There are a few data gaps in the image due to incomplete coverage by the multibeam system. Other datasets from the 1998 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.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
The measured elevations were adjusted for fluctuations in sea level during the survey by subtracting tidal elevations predicted by a tidal model and low-frequency sea level observed at the National Oceanic and Atmospheric Administration Sandy Hook tide station located at 40 degrees 28 minutes N., 74 degrees 0.6 minutes W. The tidal model utilized nine constituents derived from a 4-month bottom pressure record obtained at Station A, located at 40 degrees 23.4 minutes N., 73 degrees 47.1 minutes W. in 38 m water depth about 2.7 km east of the HARS, during the winter of 1999-2000 (Butman, Alexander, and others, 2003; see cross references). An estimate of the error due to sea level remaining in the multibeam observations after the sea level correction is about 3 cm. The vertical datum is mean lower low water.

The multibeam data were collected with a Simrad EM1000 multibeam echosounder mounted on the Canadian Coast Guard ship Frederick G. 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 1998-015-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 (UNB), Canada, was used to process and grid the multibeam bathymetric soundings and backscatter intensity data, and to produce images. An error in the University of New Brunswick (Clarke, 1998, see cross reference) processing software that resulted in the multibeam observations not being properly projected onto a plane was discovered in 2003. A second error in the gridding algorithm was discovered in 2007, requiring a shift of 1/2 grid cell to northwest. This processing step uses the corrected software. The metadata for the bathymetric grid (see larger work citation) describes the processing steps applied to the navigation and bathymetric soundings. The following processing steps produced the shaded-relief image of bathymetry, colored by backscatter intensity for the 1998 HARS data set:
1. Create a blank 8 bit map file:
Command line: make_blank mosaic_file
This command commences a dialog to enable an 8 bit image and input the map boundaries and resolution. The program also prompts for the projection type and parameters to be used creating the binary map file (custom Mercator, central longitude of -75 degrees, latitude of true scale 40 degrees north). Then the "blank" file is copied to two files required by the mosaic program:
Command line: cp mosaic_file.blank mosaic_file.mos
Command line: cp mosaic_file.blank mosaic_file.ran
2. Create backscatter files that can then be mosaicked from the backscatter time series:
Command line: getBeamPattern filename (prefix only) Command line: makess -pixel 1.0 -beam_patt beampatt filename (prefix only) output.ss Command line: glfill output.ss output.ss_fill (fills in data dropouts).
3. Mosaic all the backscatter files created in the last step (for each output.ss_fill), and then use a two point linear contrast stretch to enhance the backscatter image.
Command line: mos2 -autoseam -maxazi 10 -maxdist 10 mosaic_file output.ss_fill Command line: stretchacres -low 180 -high 220 -in mosaic_file -out mosaic_file.stretch
4. Create a shaded-relief image of the bathymetry using SwathEd routine addSUN (sun elevation of 45 degrees from 0, vertically exaggerating 4 times). The shaded relief file created from the grid is mapped into the same projection as the grid (Mercator, central longitude of -75 degrees, latitude of true scale 40 degrees north), and carries over the projection information used to create the grid.
Command line: addSUN -elev 45 -azi 0 -vert_exag 4.0 gridFile.r4 filename.shade
5. Use a two-point linear contrast stretch (0-254; 255 no data) to enhance the shaded-relief image:
Command line: stretchacres -low 150 -high 200 -in filename.shade -out filename_shade.stretch
6. Create an image of shaded-relief topography, colored by backscatter intensity:
Command line: mix_ci -c mosaic_file.stretch -i filename_shade.stretch -m mosaic_file.pseudo

Overview_Description:
Entity_and_Attribute_Overview:
Image of shaded-relief bathymetry colored by backscatter intensity. The backscatter intensity is combined with the topography to display the distribution of intensity in relation to the topography. In this image, the backscatter intensity is represented by a suite of eight colors ranging from blue, which represents low intensity, to red, which represents high intensity. These data are draped over a shaded-relief image created by vertically exaggerating the topography four times and then artificially illuminating the relief by a light source positioned 45 degrees above the horizon from an azimuth of 0 degrees. The resulting image displays light and dark intensities within each color band that result from a feature's position with respect to the light source. For example, north-facing slopes, receiving strong illumination, show as a light intensity within a color band, whereas south-facing slopes, being in shadow, show as a dark intensity within a color band. Image is 3-band, 24-bit R, G, B; (255,255,255) is no data.
