Summary

The Atlantic Beach artificial reef, located on the sea floor 3 nautical miles south of Atlantic Beach, New York in about 20 meters water depth, was built to create habitat for marine life. The reef was originally created by placing heavy materials such as tires, automobile bodies and other vehicles, barges, and rock from a dredging project on the sea floor. 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 [...]

Purpose

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 four times and then artificially illuminating the relief from the east by a light source positioned 45 degrees above the horizon. The illumination from the east, approximately parallel to the survey lines, minimizes artifacts caused by small depth changes that may occur between survey lines.
