Figure 21. 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 dendritic channels in the sea floor beneath northern Block Island Sound. Note that the channels start in storm-wave-induced scour depressions and that the channels merge downslope. 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.
