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

Figure 9. Cross-section and cores taken across the seaward end of the large rippled scour depression shown in Figure 7A (C-C'). Similar to the cores at the inshore end of this rippled scour depression, the center of the feature here is floored by a pre-existing coarse substrate. In this case, the underlying sediment is coarse shell hash and quartz sand, part of an early Holocene (?) estuarine lithosome.
