The Relationship Between Lower North Atlantic Deep Water And Rapid Climate Change During Warm Marine Isotope Stages 1, 2, and 3

主题：波义耳奖摘要科学摘要：本提案要求支持完成百慕大海隆活塞岩心中所有海洋同位素阶段（MIS）3期/期间（S/IS）事件和所有MIS 5期的深水特征（Cd/Ca）的高分辨率记录。 Cd/Ca数据将用于确定北大西洋深水流量的变化是否与S/IS事件相关，如果是，则确定S/SI事件与深水环流变化之间的相位关系。 记录适合调查温盐环流和S/SI事件之间的联系，可以开发从百慕大海隆的核心，因为积累速率足够快（30厘米/1000年），以解决个人的I/IS事件和底栖有孔虫是足够丰富的，以允许连续测量镉/钙通过S/IS事件。

Subject: summary for Boyle awardScience Summary: This proposal requests support to complete a high-resolution record of deepwater characteristics (Cd/Ca) for all of the Marine Isotope Stage (MIS) 3 stadial/interstadial (S/IS) events and for all of MIS 5 in piston cores from the Bermuda Rise. The Cd/Ca data will be used to determine if changes in North Atlantic deep water flow are associated with S/IS events and if so, determine the phase relationships between the S/SI events and changes in deep water circulation. Records suitable for investigating the links between thermohaline circulation and S/SI events can be developed in cores from the Bermuda Rise because the accumulation rates are rapid enough (30cm/1000yrs) to resolve individual I/IS events and benthic foraminifers are abundant enough to allow continuous measurements of Cd/Ca through the S/IS events.
