Comment:
Sediment depth is given in mbsf. The boundary between Subzone NPD4Bb and Zone NPD5A can be also recognized by the LCO Denticulopsis hyalina. A taxonomic problem prohibits the FO T. oestrupii from defining the subzonal boundary between NPD7Ba and NPD7b among all of three holes. Indefinite zones of NPD4Bb, 5A, 5B, 5C, and 6A in Hole 186-1151A indicate the low sedimentation rate or the presence of some hiatuses in a stratigraphic sequence.
