These GeoTIFF images represent the processed Reson 7160 multibeam echo sounder seafloor backscatter data collected by the U.S. Geological Survey during USGS field activities 2017-001-FA and 2017-002-FA along the U.S. Atlantic continental shelf break and upper slope between Accomac and Keller Canyons. The data depict seafloor bathymetry and backscatter associated with shelf-edge, submarine canyon, and upper slope environments in which seafloor methane seeps have been identified. The data are intended to be used in conjunction with other geophysical, ROV dive imagery, and geologic sample data to investigate sea-floor morphology and geologic framework associated with sites of methane seepage.
