该项目将产生烯酮不饱和度数据,以便与赤道东太平洋最近三个冰期/间冰期的浮游有孔虫中氧同位素和镁/钙比值的现有数据进行比较。目标是评估三种海洋表面温度示踪剂的一致性,如果存在系统差异,则确定可能的原因。
英文摘要
This project will generate alkenone unsaturation data to be compared with existing data on oxygen isotopes and the Mg/Ca ratio in planktic foraminifera from sites in the eastern equatorial Pacific spanning the last three glacial/interglacial cycles. The goal is to assess how well the three geocehmical tracers for sea-surface temperature agree, and if there are systematic differences, to determine the possible causes thereof.
