Figure 22. 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 sand waves in the western part of the study area. Note that most of the sand waves have transverse morphologies, but that sand waves with barchanoid morphologies and straight-crested sand waves with moats are also present. 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.
