Comment:
Hole 701A has not been studied in sufficient detail to determine depths of unconformities, which are therefore inferred using data from Hole 114-701C. There may be some difference, as the Brunhes/Matuyama boundary is shallower in Hole 114-701A (17.02 vs. 23.00 mbsf) and the Matuyama/Gauss boundary is deeper (68.73 vs. 66.70 mbsf), which may alter the ice-rafted debris data near hiatuses. The hiatus at 71.40 mbsf is inferred as the midpoint between bracketing datums 71.63 and 71.17 mbsf in Hole 114-701C. The hiatus at 174.27 mbsf is inferred as the midpoint between bracketing samples from 178.30 and 170.23 mbsf (P. F. Ciesielski, pers. comm., 1990). Repeated entries in DEPTH signify hiatuses.
