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.

急切的：概念证明：在CAPI的单盆地的湖泊水平历史上的约会：Sidney Hemming，Scott Stine和Xianfeng Wanginstitution：哥伦比亚大学PIS PIS试图一种独特而新颖的方式来表征湖泊水平的波动和使用新的C-14，U/34的Mono Lake从Mono Lake中获得湖泊水平的波动和古气候记录。 这些方法汇集了一个跨学科团队，将解决这个高风险问题。 通过记录和表征这种水文封闭的盆地，可以对区域气候变化有更深入的了解，并且可以将这种新方法用于表征时空中其他类似的盆地。 此外，单湖湖是一个敏感的环境，在加利福尼亚帝国和中央山谷的水文学中起着至关重要的作用，这是一个在经济上重要的领域。该项目适合急切的急切，因为它是1）使用新的和精制的技术来确定这些沉积物，2）是高度的风险，因为这可能是不可能的，因为这可能是可以实现的，如果可以实现这一问题，那么3）是否可以解决这个问题，并且可以解决这个问题。广泛应用于我们对该地区气候历史的理解。
