P2C2: Investigations on How Polar Climates Communicate with Each Other at the Millennial Timescale

本项目建立在研究者先前关于千年时间尺度的极地气候与海因里希事件的双极起源之间耦合的研究基础上（即极地同步假说）。研究人员将追求一些研究问题，其中最重要的是：(1)极地同步是如何和何时开始的，以及它是如何演变的？(2)由于耦合意味着信息的通信或交换，被交换的信息的性质是什么？这些科学问题目前还没有答案。主要的更广泛的影响包括对极地气候和半球间气候强迫交流有更深入的科学认识。该项目还包括本科生发现和理解古气候动力学。

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.
