From: Accumulation of an earthquake-induced extremely turbid layer in a terminal basin of the Nankai accretionary prism

Figure 2

Bathymetric map, heat-flow probe system, CAM-B image, and video images of ripple-like bedforms. Bathymetric map (upper left) of the terminal basin in the prism slope; contour interval is 20 m (see Figure 1 for location). Yellow wavy lines show the crest directions of ripple-like structures. Thick line indicates the route of the subbottom profiling survey of dive 124. The black portion of the profile line, from S1 to S3, is shown in Figure 7. An orange circle denotes the site NG2 surveyed during the dives 40, 41, 42, and 87. The upper right photo shows the heat-flow probe system suspended from the pilot vehicle. The inset photo is a black-and-white camera (CAM-B) image of a heat-flow instrument during dive 30 that is completely submerged in the bottom turbid layer. Lower panels show video images of ripple-like bedforms: (a, c) catenary shape at the slope regions and (b) linguoid shape at the basin floor (b).
