K-1-93-HW Seismic Profiles, Trackline 7

High resolution 3.5 kHz profile collected on line 7 over the former Pearl Harbor disposal site. The figure shows the lateral discontinuity or lateral variation in reflectivity of the wavy seafloor, the general featureless nature of the subsurface, and diffraction patterns that correlate with bedforms on the sidescan sonar mosaic. These bedforms are also visible on bottom photographs collected during the 1977-1978 site designation studies (Chave and Miller, 1977a, 1977b, 1978a, 1978b; Tetra Tech, 1977; and U.S. Environmental Protection Agency, 1980), and the U. S. Geological Survey 1994 sampling cruise (Torresan and others, 1994b). Read more about this portion of the Mamala Bay study.
