This project builds upon previous research by the investigator regarding the coupling between polar climate at millennial time scales and the bi-polar origin of Heinrich events (i.e., the polar synchronization hypothesis). The researcher will pursue a number of research questions, among the most important being: (1) How and when did polar synchronization start, and how did it evolve? and (2) What is the nature of the information being exchanged since coupling implies communication or exchange of information? These scientific questions are currently unanswered.The primary Broader Impacts involve greater scientific understanding of polar climate and inter-hemispheric communication of climate forcing. The project also involves undergraduate students in the discovery and understanding of paleoclimate dynamics.

该项目基于研究者先前的研究，千年时间尺度上极性气候与海因里希事件的双极起源（即极地同步假设）。研究人员将提出许多研究问题，其中最重要的是：（1）极性同步如何以及何时启动，它是如何发展的？ （2）由于耦合意味着信息交流或交换信息，因此要交换的信息的性质是什么？这些科学问题目前尚未得到解决。主要的广泛影响涉及对极地气候和气候强迫的半球间交流的更多科学理解。该项目还涉及本科生参与对古气候动态的发现和理解。
