Stratigraphy
Stratigraphic resolution:group of beds
Stratigraphy comments: "The core provided a continuous record from marine isotope stage (MIS) 18 (750 ka) to the present, a period that spanned the Brunhes normal polarity epoch (0–740 ka). The age model of this core was established through measurement of the stable oxygen isotopes of benthic foraminifera and calcareous nannofossil datums (Domitsu et al. 2011)." (Matsuzaki et al. 2014)
"The stratigraphical interval between sample 3H-4 at 42–48 cm (20.91 mbsf) and the top of core 902-C9001C (0 mbsf). This zone covers the period from 33 to 0 ka." (Matsuzaki et al. 2014)
