Figure 11. Detailed view of the original (left) and enhanced (right) sidescan-sonar mosaics from the southern part of the Quicks Hole survey by the National Oceanic and Atmospheric Administration. Note the tonal artifacts in the original mosaic and how removal of the artifacts presents a more continuous tonal character. Circles mark sampling and bottom-photography station locations (Poppe and others, 2007a); each is labeled with station number and mean grain-size value (phi). Locations of views are shown in figure 10.
