This GeoTIFF image represents approximately 7 square kilometers of interferometric sonar backscatter data that were collected in Red Brook Harbor, Massachusetts, by the U.S. Geological Survey in 2009 as part of USGS survey 09018. Data were collected with a Systems Engineering and Assessment Ltd. (SEA) SWATHplus interferometric sonar system. These data are used to define the sea-floor morphology as part of the Massachusetts Sea-floor Mapping Project. The cell size for this image is 1-meter by 1-meter.
