Figure 11. Detailed sidescan-sonar and bathymetry images of sand waves along a channel on the northern ridge. Sand waves adjacent to the channel are straight-crested and oriented north-south; away from the channel sand waves have more curved and sinuous crests that are oriented east-west. In the channel in the central part of the image, both east-west and north-south oriented sand waves are present, suggesting complex flow and transport directions. Benches are also visible on the sidescan-sonar image where there is a sharp curvilinear change in backscatter. A trawl mark is visible in the southeastern corner of the sidescan-sonar image. Light and dark bands oriented northeast-southwest are artifacts in the sidescan sonar. Location of figure shown in fig. 2.
