本项目将确定大湖盆地前冰期湖泊的全新世早期历史，以确定它们对区域气候的影响。年龄，同位素，湖泊。水平和花粉组合信息将强烈限制北大西洋劳伦潮融水引起的同位素信号的时间和大小，特别是应该有助于限制新仙女木期冷却的各种假设。
英文摘要
This project will determine the early Holocene history of the proglacial lakes in the Great Lake basin to determine their effect on the regional climate. The age, isotopic, lake.level and pollen assemblage information will strongly constrain the timing and magnitude of the isotopic signals caused by Laurentide meltwaters in the North Atlantic and in particular should contribute to restricting the various hypotheses of Younger Dryas cooling.
