Figure 24. Detailed planar view of the bathymetric data collected during National Oceanic and Atmospheric Administration survey H11922 showing the gradual transition from winnowed bouldery sea floor to the surrounding Holocene deposits in the south-central part of the study area and the location of station 922-14. Note the presence of megaripples, and fingers of eroded Holocene deposits creating a valley and ridge type topography. Location of view is shown in figure 21.
