Notes: LO = last occurrence, LCO = last common occurrence, B = base, FO = first occurrence, T = top, * = diatom datums from Hole 1151A sediment. In Holes 1151C and 1151D, these diatom datums were ~20 m shallower. Values in parentheses are from Holes 1151C and 1151D. This table is also available in ASCII format.
