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.

EAGER：概念证明：莫诺盆地湖水位历史 U-Th 测年，CAPI：Sidney Hemming、Scott Stine 和 Xianfeng Wang 机构：哥伦比亚大学 PI 正在尝试一种独特而新颖的方法，使用新改进的 C-14、U/Th 和 40Ar/39Ar 方法来表征莫诺湖的湖水位波动和古气候记录。 这些方法汇集了一个跨学科团队来解决这个高风险问题。 通过记录和表征这个水文封闭盆地，可以更好地了解区域气候变化，并且这种新方法可用于表征其他类似盆地的空间和时间特征。 此外，莫诺湖是一个敏感的环境，在加利福尼亚帝国和中央谷的水文中发挥着至关重要的作用，该地区是一个经济重要的地区。该项目适合 EAGER，因为它 1) 使用一种新的和完善的技术来测定这些沉积物的年代，2) 风险很高，因为不确定这是否可以实现，3) 召集一个跨学科团队来解决这个问题，4) 如果成功，可以用于其他系统，例如这个系统和 广泛应用于我们对该地区气候历史的理解。
