Torresan, M.E., and Gardner, J.V.,2000, Acoustic Mapping of the Regional Seafloor Geology in and Around Hawaiian Ocean Dredged-Material Disposal Sites, U.S. Geological Survey Open-file Report 00-124.

See Figures 12 and 13 for location of disposal site and compare to multibeam map in Figure 15. Note that the bedforms apparent in the multibeam maps are subtle at best in the sidescan data. In both data types the dredged material deposits appear as isolated high-backscatter circular features that coalesce to form a nearly continuous high-backscatter blanket. When compared to the multibeam image (Figure 15) the sidescan appears to resolve the boundaries of individual circular high-backscatter features better than the multibeam data. Scale across the bottom of the image is 5.5 km.
