Figure 15. A bathymetric image of boulders in the study area.

Figure 15. Detailed planar view of the bouldery sea floor northwest of Rocky Point from the digital terrain model produced from bathymetric data collected during National Oceanic and Atmospheric Administration survey H11997. Boulders rest on the winnowed northern flank of the submerged Harbor Hill-Roanoke Point-Fishers Island end moraine. Scour-mark asymmetry around the boulders suggests net westward to southwestward sediment transport. Location of view is shown in figure 12.
