Stable isotope ratio of G. sacculifer in sediment core MD99-2198 (0-125 ka)@en

Stable isotope ratios in planktic foraminifera were measured every 20 cm for the upper 0-18.5 m and every 10 cm between 18.5-22 cm (revised depth). Note that the original core depth scale in core MD99-2198 was modified by excluding two intervals (10.06-10.24 m and 13.78-14.30 m), representing episodes where the core was ripped apart, as could be concluded on the basis of large increases in porosity.对岩芯MD99-2198中浮游有孔虫（planktic foraminifera）的稳定同位素比值进行了测试：上部0~18.5 m层段以20 cm为间隔采样测试，18.5~22 m（修正后深度）层段则以10 cm为间隔采样测试。需注意：MD99-2198岩芯的原始深度标尺已通过剔除两段层段（10.06~10.24 m与13.78~14.30 m）完成修正，这两段对应岩芯发生撕裂的时段，该结论基于孔隙度显著升高的观测结果得出。
