Figure 42. Detailed planar view along the southern edge of the sidescan-sonar mosaic produced during National Oceanic and Atmospheric Administration survey H11077 of Woods Hole, Massachusetts, showing relatively straight to sinuous alternating bands of high and low backscatter (“tiger-stripe”) pattern indicative of transverse sand waves. Note the abundance of megaripples between and on the stoss slopes of the waves indicative of active transport, and that the crest orientation of the sand waves and megaripples does not always match. Location of view is shown in figure 19.
