Figure 20. 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 storm-wave-induced scour depressions on an isolated bathymetric high in eastern Rhode Island Sound. The presence of boulders suggests that winnowed Pleistocene deposits are exposed on the floor of the depression. Note the relatively smooth appearance of the modern marine sediments and the presence of outliers. 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.
