Butman, Bradford, Danforth, W.W., Clarke, J.E.H., and Signell, R.P., 2017, Bathymetry and backscatter intensity of the sea floor of the Sandy Hook artificial reef, offshore of New Jersey: U.S. Geological Survey data release,


The Sandy Hook artificial reef, located on the sea floor offshore of Sandy Hook, New Jersey was built to create habitat for marine life. The reef was created by the placement of heavy materials on the sea floor; ninety-five percent of the material in the Sandy Hook reef is rock. In 2000, the U.S. Geological Survey surveyed the area using a Simrad EM1000 multibeam echosounder mounted on the Canadian Coast Guard (CCG) ship Frederick G. Creed. The purpose of this multibeam survey, done in cooperation with the U.S. Army Corps of Engineers when the Creed was in the New York region in April 2000, was to map the bathymetry and backscatter intensity of the sea floor in the area of the Sandy Hook artificial reef. The collected data from this [...]

The GeoTIFF image of shaded-relief bathymetry provides a visualization of the bathymetry that accentuates small features that cannot be effectively shown as contours alone. The image was created by vertically exaggerating the bathymetry three times and then artificially illuminating the relief from the north by a light source positioned 45 degrees above the horizon. The illumination from the north, approximately parallel to the survey lines, minimizes artifacts caused by small depth changes that may occur between survey lines.
