Summary: This ESH project will analyze alkenone unsaturation as a proxy for sea surface temperature in sediments from the Bermuda Rise at sample intervals of 100 years for the last 450,000 years. The goal is to construct a highly-resolved record of SST that can be compared with variations in the Vostok ice core to assess the timing and occurrence of rapid (millennial) variations and to serve as a reference section for North Atlantic variability comparable to the Greenland ice core record.

摘要：该ESH项目将分析过去45万年百慕大隆起100年一次的沉积物中的烯烃不饱和度作为海表面温度的替代指标。目标是建立一个高分辨率的SST记录，可以与Vostok冰芯的变化进行比较，以评估快速(千年)变化的时间和发生情况，并作为可与格陵兰冰芯记录相媲美的北大西洋变化的参考部分。
