This data release makes the multibeam echosounder data from the 1998 survey of the sea floor offshore of Shinnecock Inlet, New York, available in digital form. 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 an azimuth of 60 degrees. The illumination from 60 degrees, 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).
