Figure 14. Detailed multibeam bathymetric image of barchanoid megaripples, boulders, and trawl marks in the southwestern part of the study area. The barchanoid megaripples have tails pointing towards the east, reflecting an eastward sediment transport direction. Faint troughs can be seen in the deep parts of the image, which are trawl marks caused by fishing gear dragging along the sea floor. Location of image is shown in figure 11.
