Backscatter intensities acquired in this study linearly mapped to a greyscale mosaic with a resolution of 1 m and dynamic mosaic range of -41.2–15 dB. Light blue contours: M7000 digital bathymetry data. Three characteristic backscatter imagery facies are identified (boundary traced by green-dotted lines). Facies 1: heterogeneous, moderate reflective (light grey) facies. Facies 2: homogeneous, weak-to-moderate reflective (dark grey) facies. Facies 3: homogeneous, moderate-to-strong reflective (light grey) facies. Black lines: seismic reflection survey lines (#1–15). Red line: Trace of the Osaka Bay Fault.
