9618641 Bond This project will test preliminary findings of millennial (1500-year) cycles in North Atlantic surface circulation during the Holocene. The PIs will analyze existing sediment cores and collect new ones from a wide area of the North Atlantic, focusing on sites with very high sedimentation rate. Analyses will include concentrations of planktic foraminifera as well as alkenone analyses on bulk sediment. If preliminary findings are confirmed, it may be possible to predict future natural climate variability, at least on millennial timescales, in the region.

该项目将测试全新世期间北大西洋表层环流千年（1500年）周期的初步发现。pi将分析现有的沉积物岩心，并从北大西洋的广大地区收集新的沉积物岩心，重点是沉积速率非常高的地点。分析将包括浮游有孔虫的浓度以及对大块沉积物的烯酮分析。如果初步发现得到证实，就有可能至少在千年时间尺度上预测该地区未来的自然气候变率。
