K-1-93-HW Seismic Profiles, Trackline 11a

Bedforms (possibily sandwaves), as seen on a 3.5 kHz profile collected along line 11, located on the south east side of the plume-shaped former Honolulu Harbor site. The bedforms here are more pronounced than those visible in trackline 5a, and like trackline 5a, the bedforms start within the eastern edge of the former Honolulu Harbor disposal site, and extend about 2 km into the low backscatter seafloor that is unaffected by dredged material disposal.
