Figure 45. Detailed perspective view of the bathymetry looking east across the sand-wave field in the channel west of Great Ledge from the digital terrain model produced during National Oceanic and Atmospheric Administration survey H11077 of Woods Hole, Massachusetts. Line shows location of transect; cross section shows scaled bathymetry and that sand-wave asymmetry indicates net northward transport along the western side of this sand-wave field. Location of view is shown in figure 19.
