Torresan, M.E., Hampton, M.A., Gowen, M.H., Barber, Jr., J.H., Zink, L.L., Chase, T.E., Wong, F.L., Gann, J.T., and Dartnell, P., 1995, Final report: acoustic mapping of dredged material disposal sites and deposits in Mamala Bay, Honolulu, Hawaii: U.S. Geological Survey Open-file Report 95-17.
Figure 12. HighÐresolution 3.5ÐkHz profile collected on line 7 over the former Pearl Harbor disposal site. The figure shows the lateral discontinuity or lateral variation in reflectivity of the seafloor, the general featureless nature of the subsurface, and diffraction patterns that correlate with bedforms on the sidescan sonar mosaic. These bedforms are also visible on bottom photographs collected during the 1977Ð1978 site designation studies (Chave and Miller, 1977a, 1977b, 1978a, 1978b; Tetra Tech, 1977; and U.S. Environmental Protection Agency, 1980), and the U. S. Geological Survey 1994 sampling cruise (Torresan and others, 1994b).
