Creation of ultra-high resolution multibeam sonar images targeting deep sea coral habitats in Hudson Canyon

Figure 4. Backscatter image from 2009 cruise showing putative coral mounds: dark, high backscatter spots surrounded by light, low backscatter sediments. Red oval is the same area as seen in the lower right portion in Fig. 3. Green oval is high backscatter area on steep slope, probably a rock outcrop.
