Figure 4.6. Shoreface geology along the northern Grand Strand at Waites Island. (TOP) Perspective view showing a complex pattern of acoustic backscatter on the shallow seafloor. High backscatter (light shades) generally indicates coarse sand, gravel, and rock. Low backscatter (darker shades) generally indicates sandy or muddy sediment. (A-B) Interpreted subbottom profiles showing the geologic framework underlying the shoreface. See Figure 4.2 for location. ~, about. [Click here for high-resolution image.]
