Figure 13. Detailed bathymetric image of sand waves and megaripples in the southeastern part of the study area. Sand waves have crests that range from north-south to northeast-southwest, whereas megaripple crests range from north-south to northwest-southeast, becoming almost normal to the sand-wave crests in the west. Locations of sand-wave profiles A-A’ and B-B’ are also shown. Location of image is shown in figure 12.
