Correlation of interpreted seismic surfaces with the surfaces seen on the shelf is only tentative. Surface pp4(s) is interpreted to occur at or near the Pleistocene/Pliocene boundary. Note good correlation of gamma-ray cycle boundaries with interpreted seismic surfaces. Gamma-ray profile above 88 mbsf (just below pp1[s]) was acquired through the BHA and has been shifted to the right to match the open-hole interval below, the absolute values above 88 mbsf are therefore only qualitative.
