Map showing acoustic-backscatter intensity of the seafloor in the survey area, south of Martha's Vineyard and north of Nantucket, Massachusetts. Backscatter intensity is an acoustic measure of the hardness and roughness of the seafloor. In general, higher values (light tones) represent rock, boulders, cobbles, gravel, and coarse sand. Lower values (dark tones) generally represent fine sand and muddy sediment. UTM, Universal Transverse Mercator; WGS 84, World Geodetic System of 1984.
