Figure 20. CHIRP sub-bottom profiles with interpretations from the shoreface-attached and shoreface-detached ridges offshore Pawleys Island. These profiles provide sub-bottom images of the features, illustrating their cross sectional profiles. The images also illustrate how the strata underlying the features crop out in the swales between them. Vertical scales for sub-bottom profiles are provided in both milliseconds (Two-Way Travel Time) and approximate depth in meters (assuming a seismic velocity of 1500 m/s). Locations for profiles J - J' and K - K' are outlined in Figure 7.
