The GeoTIFF image of shaded-relief bathymetry, pseudocolored colored by backscatter intensity, provides a visualization of both bathymetry and backscatter intensity. The shaded-relief 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 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).
