中文摘要
项目负责人:Sidney Hemming, Scott Stine, and咸丰wangxianfeng, CAPI(s): Sidney Hemming, Scott Stine, and咸丰wangxianfeng机构:哥伦比亚大学项目负责人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Mono湖的湖泊水位波动和古气候记录。这些方法汇集了一个跨学科的团队,将解决这一高风险问题。通过对这一水文封闭盆地的记录和表征,可以更好地了解区域气候变化,这种新方法可以用于表征其他类似盆地的空间和时间特征。此外,Mono湖是一个敏感的环境,在加州帝国谷和中央谷的水文中起着至关重要的作用,这是一个重要的经济地区。这个项目适合于EAGER,因为它1)使用了一种新的和精细的技术来确定这些沉积物的年代,2)风险很高,因为它不确定是否可以实现,3)汇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。
英文摘要
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.
