English: Hillshaded seafloor three dimensional perspective view illuminates the striking mass wasting and faulting features of the Orca Basin. Water depths are 1800 meters at the rim of the basin and 2400 meters to the basin floor. At elevation 2151 meters below sea level, a hypersaline anoxic brine pool covers the bottom of the Orca Basin, which is fed by a seafloor-outcropping salt dome on the eastern flank. DSDP Leg 96 Site 618 (circle) collected 92.5 meters of core through landslide deposit in the northern sub-basin. Two industry wells (stars) were drilled on either side of the headwall of the prominent landslide on the southern flank. 3D seismic dataset is outlined in black. SP = spill point of the Orca Basin (139  meters) above the elevation of the brine pool which leads to the adjoining Jefferson Basin. A possible small accumulation of brine occurs in the low in the southern portion of the basin in line C-C′.
