Sidescan-Sonar Imagery of the Shoreface and Inner Continental Shelf, Wrightsville Beach, North Carolina

Figure 7A: The rippled scour depressions on the Wrightsville Beach shoreface are up to 1 m deep, and are floored by coarse shell hash, sand and gravel. As shown here, as well as in Figures 1 and Figure 6 , the northern edges (contacts between coarse and fine sediments) of the rippled scour depressions are sharp. The southern contacts, however, appear more ragged or "wisply."
