Figure 38. Distribution of sedimentary environments based on the digital terrain model from combined National Oceanic and Atmospheric Administration (NOAA) surveys H12009, H12010, H12011, H12015, H12033, H12137, and H12139; unpublished NOAA survey H12299 located adjacent to the southwestern corner of the (DTM); and the sampling and photography data from U.S. Geological Survey cruise 2011-006-FA that were used to verify the acoustic data. Areas characterized by processes associated with erosion or nondeposition, coarse bedload transport, sorting and reworking, and deposition are shown.
