AbstractUnder this award the PIs will probe the nature of high latitude influences on tropical oceanography during the late Pleistocene 41 kyr regime. The PI will increase knowledge of how high latitude processes interact with the tropical oceans to produce large-scale changes. The PIs will determine: Amplitudes of SST change at orbital frequencies in the 1.2-1.8 Ma at various tropical lcations. Correlation of SST changes to thermocline proxies at each site. Correlation of multiple proxies, where obtained (e.g. Mg/Ca, C37total vs. F. profunda). Phase relations of SST change to benthic d18O and presence/absence of a circa 100 kyr component to SST

摘要在这个奖项下，PI将探讨在晚更新世41 kyr政权的热带海洋学的高纬度影响的性质。 PI将增加高纬度过程如何与热带海洋相互作用以产生大规模变化的知识。 PI将确定：在1.2-1.8 Ma的轨道频率在不同的热带lcations的SST变化幅度。在每个站点SST变化与温跃层代理的相关性。获得的多个替代指标的相关性（例如Mg/Ca，C37总与F。profunda）。SST变化与底栖d18 O的相位关系和SST存在/不存在大约100 kyr分量
