K-1-93-HW Seismic Profiles, Trackline 4

Bedforms within the former Honolulu Harbor dredged material disposal site as seen on a 3.5 kHz profile. The profile is from line 4 collected across the central portion of the former Honolulu Harbor site. Note that for this profile and succeeding 3.5 kHz profiles the seafloor reflector is typically purple in color and is located below an irregular green signature (reflector). The green above the purple is an artifact of the display software incorporated with the profiling system. Read more about this portion of the Mamala Bay study.
