Figure F2. A. Oxygen isotope curve (¹⁸O ratio vs. Peedee belemnite standard) of surface-dwelling planktonic foraminifer Globigerinoides ruber from Site 1144. Sampling density is listed in Table T1. Dashed line at –2.6‰ indicates the Holocene average ¹⁸O level. Numbers are marine isotope stages and/or substages. YD = Younger Dryas. Asterisks = position of ¹⁴C datings, line of open dots = microtektite layer. Solid vertical lines show position of hiatuses. Thin vertical lines below 235 mcd indicate core breaks. B. Carbon isotope record (¹³C ratio) of surface-dwelling planktonic foraminifer G. ruber from Site 1144. Roman numerals show position of glacial terminations.
