Figure 20. A diagram of sand-wave cross sections.

Figure 20. Cross-sectional views of transverse sand-waves from the western part of the digital terrain model produced from bathymetric data collected during National Oceanic and Atmospheric Administration survey H11997. Sand wave asymmetry indicates a westward net sediment transport; the presence of megaripples on stoss slopes suggests transport is active. Locations of profiles are shown in figure 12.
