Figure F1. Carbon and oxygen isotopic data for ODP Site 1146 composite section. Data are reported in per mil () relative to Vienna Peedee belemnite (VPDB). Selected marine isotope stages are labeled. A. Benthic 18O and 13C plotted on the meters composite depth (mcd) scale. B. Planktonic 18O and 13C plotted on the mcd scale. C. Benthic 18O and 13C plotted as a function of age. D. Planktonic 18O and 13C plotted as a function of age.
