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

Figure 6A: Enlarged image of sidescan-sonar imagery showingthe meter-wavelength ripples that floor the rippled scour depressions (see Figure 5 for location). Ripples in the fine sand are below the resolution of the sidescan system. Note the sharp contact between coarse and fine sediments. Note also the small package of finer sediments within the rippled scour depression. The crests of the larger ripples can be "seen" through this thin deposit.
