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 shaded-relief image was created by vertically exaggerating the bathymetry 10 times and then artificially illuminating the relief from the northeast (45 degrees, approximately parallel to the survey tracklines) by a light source positioned 30 degrees above the horizon. The illumination from the northeast, approximately parallel to the survey lines, minimizes artifacts caused by small depth changes that may occur between survey lines and accentuates subtle downslope features.
