This project will analyze planktic foraminiferal assemblage and stable isotopes over the last full glacial/interglacial cycle in ODP site 1002 from the Cariaco Basin. Time slices will be sampled at 100-year intervals to provide records of century to millenial variability during glacial maxima (Stages 2 and 4) and the last interglacial maximum (Stage 5e). Results will address millenial variation in the tropics under extreme climate states, and can be directly compared to high-latitude records from Greenland ice cores to assess large-scale linkages.

该项目将分析Cariaco盆地ODP 1002站最后一个完整冰期/间冰期循环的南极有孔虫组合和稳定同位素。 将以100年为间隔对时间切片进行采样，以提供最大冰期（第2和第4阶段）和最后一次间冰期最大冰期（第5e阶段）期间世纪至千年变化的记录。 研究结果将解决极端气候状态下热带地区千年变化的问题，并可直接与格陵兰冰芯的高纬度记录进行比较，以评估大规模的联系。
