项目摘要

This collaboration between professors and students at North Dakota State University and Middlebury College will reconstruct changes in climate and surface water in the southwestern United States between 20,000 and 11,500 years ago. These changes caused glaciers and lakes to expand during the last glaciation, and then disappear entirely as climate warmed. Reconstructing the climatic conditions that drove this behavior will yield important information about how quickly climate and resulting surface water resources can change, which will improve projections of future surface water changes under a warming climate.The magnitude and pace of temperature and precipitation changes in the southwestern United States at the end of the last glaciation have been difficult to resolve. This project will use a new approach that has shown promise in smaller-scale applications. Glaciers and lakes respond to changes in temperature and precipitation with differing sensitivities. Studying geologic records of former glaciers and lakes simultaneously, therefore, provides the opportunity to identify the relative roles of temperature and precipitation in driving glacier and lake behavior. This project will combine field-based geologic data with computer modeling to quantify changes in temperature and precipitation during the last episode of major climatic change in the southwestern United States.

北达科他州州立大学和米德尔伯里学院的教授和学生之间的这项合作将重建20,000年至11,500年前美国西南部气候和地表水的变化。这些变化导致冰川和湖泊在最后一次冰期扩大，然后随着气候变暖而完全消失。重建驱动这种行为的气候条件将产生关于气候和由此产生的地表水资源变化速度的重要信息，这将改善对气候变暖下未来地表水变化的预测。末次冰期结束时美国西南部温度和降水变化的幅度和速度一直难以解决。该项目将使用一种新的方法，这种方法在小规模应用中表现出了希望。冰川和湖泊对温度和降水变化的敏感性不同。因此，同时研究前冰川和湖泊的地质记录，可以确定温度和降水在驱动冰川和湖泊行为中的相对作用。该项目将把联合收割机实地地质数据与计算机建模相结合，以量化美国西南部最后一次重大气候变化期间的温度和降水变化。
