Figure 18. Detailed sidescan-sonar image of boulders with scour marks at the eastern end of the study area. Scour depressions to the east of the boulders indicate net eastward bottom currents; higher backscatter in the depressions indicates the presence of coarser grained sediments. Dark stripes in the middle of sonar lines are nadir gaps. Location of image shown in figure 17. |
