Figure 24. Detailed planar view of the sun-illuminated bathymetry from the combined National Oceanic and Atmospheric Administration surveys in Rhode Island and Block Island Sounds showing the relatively flat, featureless appearance of modern (Holocene) marine sediments, a shipwreck, and artifacts from multibeam acquisition and processing. The shipwreck is a German submarine sunk during World War II. Note the absence of asymmetrical scour around the wreck. Location of view is shown in figure 11. Warmer colors denote shallower areas; cooler colors denote deeper areas. Depth key is shown in figure 9.
