Depth, calendar age, concentrations of C37 alkenones, UK`37 and alkenones SST of sediment core GGC15 in the Ohkotsk Sea

Calendar age was calculated based on 14C dating (7 points) of planktonic foraminifera (N. pachyderma) (Keigwin, 1998). <10 = not detected, detection limit is ca. 10 ng/g-dry sediments.

基于放射性碳-14测定法（7个数据点）对浮游有孔虫（N. pachyderma）的年龄进行了计算（Keigwin，1998年）。未检测到的情况以<10表示，检测限约为10 ng/g干沉积物。
