K-1-93-HW Seismic Profiles, Trackline 6c

High resolution 3.5 kHz profile from line 6, west of the South Oahu disposal site. Note the wavy seafloor reflector diffraction patterns that typify profiles collected bedforms. Note also the change in seafloor reflectivity near the left (west) side of the profile, resulting from a gain change in the profiling and recording system.
