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 8. A 3.5–kHz profile from line 5 across the eastern portion of the former Honolulu Harbor disposal site showing undulating bedforms. The bedforms start within the eastern most edge of the high–backscatter feature associated with the former Honolulu Harbor disposal site. The mounds extend east nearly 2 km beyond the high–backscatter deposit into the low–backscatter seafloor, thus suggesting that the mounds result from natural rather than anthropogenic processes.
