EAGER: Proof of concept: U-Th Dating of Lake-level History at Mono Basin, CAPI(s): Sidney Hemming, Scott Stine, and Xianfeng WangINSTITUTION: Columbia UniversityThe PIs are attempting a unique and novel way to characterize lake-level fluctuation and paleoclimate records from Mono Lake using newly refined C-14, U/Th and 40Ar/39Ar methods. These methods bring together an interdisciplinary team that will address this high risk problem. By documenting and characterizing this hydrographically closed basin, a greater understanding of regional climate variations can be made and this new approach can be used in characterizing other similar basins in space and time. In addition, Mono Lake is a sensitive environment and plays a critical role in the hydrology of the Imperial and Central Valley of California, which is an economically important area.This project is appropriate for an EAGER because it 1) uses a new and refined technique to date these sediments, 2) is high risk because it is uncertain that this might be achievable, 3) brings together an interdisciplinary team to address this problem and 4) if successful, can be used for other systems like this one and be broadly applied to our understanding of the climate history in this region.

热切：概念验证：莫诺盆地湖平面历史的U-Th测年(S)：西德尼·海明，斯科特·斯汀，以及哥伦比亚大学先锋王兴他们正在尝试一种独特而新颖的方法来表征莫诺湖的湖平面波动和古气候记录，使用新改进的C-14，U/Th和40Ar/39Ar方法。这些方法汇集了一个跨学科团队，将解决这一高风险问题。通过记录和描述这个水文封闭的盆地，可以更好地了解区域气候变化，这种新的方法可以用于在空间和时间上描述其他类似的盆地。此外，莫诺湖是一个敏感的环境，在加州帝国河谷和中央山谷的水文学中扮演着关键的角色，这是一个重要的经济区域。这个项目适合渴望的人，因为它1)使用一种新的和改进的技术来测定这些沉积物的年龄，2)高风险，因为这是否可能实现，3)聚集了一个跨学科的团队来解决这个问题，4)如果成功，可以用于其他系统，如这个系统，并广泛应用于我们对该地区气候历史的理解。
