The purpose of this GeoTIFF is to publish the acoustic backscatter of the seafloor acquired with the 117-kHz SWATHplus interferometric sonar offshore of Massachusetts within northern Cape Cod Bay. The Klein 3000 sidescan sonar was primary sonar used to acquire acoustic backscatter during surveys 06012, 07001, 07002, and 08002. However, during August 1-2, 2007 (07002), the winch used to deploy the Klein 3000 sidescan sonar towfish was inoperable. The acoustic backscatter acquired with the 117-kHz SWATHplus interferometric sonar was processed to cover this data gap in the Klein 3000 backscatter data.
