This project tests the hypothesis that enhanced climate sensitivity to obliquity forcing, which is known to have begun ~3Ma, can be linked to a change in the mean state of the tropical Pacific surface ocean and the associated change in the oceanic heat balance. The PI will compare high-resolution planktonic and benthic stable isotope and alkenone records from two sites, representing heat gain (equatorial Pacific) and heat loss (North Pacific) regions. The time period of interest spans the late Pliocene transition (3.6-1.8 Ma). The project will be the basis for one PhD dissertation and an undergraduate honors thesis, and the results will be incorporated into a module of the Deep Earth Academy?s ?School of Rock?.

该项目检验的假设是，增强气候敏感性的强迫，这是已知的开始~ 3 Ma，可以联系到热带太平洋表层海洋的平均状态的变化和相关的海洋热平衡的变化。 PI将比较来自两个地点的高分辨率海洋和海底稳定同位素和烯酮记录，代表热量增加（赤道太平洋）和热量损失（北太平洋）区域。感兴趣的时间段跨越上新世晚期的过渡（3.6-1.8马）。该项目将是一个博士论文和本科生荣誉论文的基础，其结果将被纳入深地学院的一个模块。是什么？摇滚学校？
