Map showing study area of the Deepwater Canyons expeditions

Location of (A) Baltimore and (B) Norfolk canyons and adjacent slope environments along the U.S. Mid-Atlantic margin. The bathymetry represents 25 m gridded multibeam data with contour lines at every 100 m. Colors on the bathymetric scale represent depth from shallow (red) to deep (blue). Sampling locations from 2011 to 2013 for stable isotope analyses are designated by the following symbols: square = flora, circle = fauna, triangle = sediment, and diamond = particulate organic matter (POM).
