Notes: PF = planktonic foraminifer, MS = magnetostratigraphy, CN = calcareous nannofossil. FO = first occurrence; LO = last occurrence. The datum level for G. flexuosa is considered unreliable and should be discarded when calculating sedimentation rates. High sedimentation rates from the lower part of the hole need confirmation by postcruise studies.
