Bottom-simulating reflector is present on ~50% of the midcontinental slope (shaded area) (from Riedel et al., 2006). B. Multibeam bathymetry map along the transect across the accretionary prism, showing the location of the drilling transect (Sites U1326, U1325, U1327, U1329), cold vent Site U1328, and multichannel seismic (MCS) Line 89-08 (Courtesy of D.
