Figure F4. Correlation of ¹⁸O and inorganic carbon (IC) profiles with sediment color of largest sediment core GC-10 (site CS-03). Shaded regions are interpreted as glacial periods represented by marine isotope stages (MIS) 2, 4, and 6, which are characterized by higher ¹⁸O values, lower IC content, and darker sediment color. Our nannofossil age, start of E. Huxleyi acme Zone at ~300 cm subbottom depth, is indicated with a dashed line. 1 errors are 0.06‰ for ¹⁸O and 0.2 wt% for IC.
