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：这个ESH项目将分析在过去45万年中，以100年为样本间隔的百慕大上升沉积物中的烯酮不饱和度作为海面温度的代表。目标是建立一个高分辨率的海温记录，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，并作为与格陵兰冰芯记录相当的北大西洋变率的参考部分。
