Figure 18. A bathymetric image of transverse sand waves in the study area.

Figure 18. Detailed planar view of transverse sand waves from the digital terrain model produced from bathymetric data collected during National Oceanic and Atmospheric Administration survey H11997. Note that the transition from the surrounding gravel pavement is abrupt and that megaripples progressively give way to sand waves which in turn are replaced by sand waves covered with megaripples. Location of view is shown in figure 12.
