Butman, Bradford, Danforth, W.W., Clark, J.E.H., Signell, R.P., and Schwab, W.C., 2016, Bathymetry and backscatter intensity of the sea floor south of Long Island, New York: U.S. Geological Survey data release,


These data are from a 1998 multibeam survey of the sea floor offshore of Fire Island Inlet, New York. There are five datasets: bathymetry grid, shaded-relief image, backscatter intensity image, shaded-relief colored by backscatter intensity image, and trackline navigation. The bathymetry shows the shape of the sea floor. Of particular interest are the size, shape, and orientation of bed forms that may indicate sediment movement. The shaded-relief image provides a visualization of the bathymetry that accentuates small features that cannot be effectively shown as contours alone. The image of backscatter intensity provides qualitative information on the sediment texture and roughness of the sea floor. The image of shaded-relief bathymetry, [...]
