TRANSCRIPT
Figure 6. Sidescan-sonar imagery showing linear, high-backscatter features interpreted to be rippled scour depressions (RSDs) offshore of Long Beach, New York. The RSDs are floored, in part, with rippled sandy gravel and gravelly sand. Areas between the RSDs are comprised of fine sand. High backscatter is represented by light tones, low backscatter by dark tones. See Figure 3 for location.
