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 10. High-resolution 3.5kHz profile from line 6 over the active South Oahu disposal site. Note how the seafloor here is not like that over portions of the former Honolulu Harbor site (figures 7 and 8). Note the lateral discontinuity in seafloor reflectivity as shown by the subtle variation in the color of the seafloor reflector from dark purple to lighter purple. Also evident is the structureless nature of the subsurface and lack of subsurface resolution typical of most profiles collected over the disposal sites.
