Collaborative Research: Hydrologic Variability in the Pacific Northwest During the Past 13,000 Years from High-Resolution Studies of Finely Laminated Lake Sediments

该奖项支持在华盛顿中北部地区进行精细分层湖泊沉积物的多代理研究。 研究人员将调查东北太平洋地区过去13,000年来大规模气候强迫，区域气候变化以及植被和湖泊响应之间的复杂关系。 这项研究的总体目标是审查区域降水蒸发平衡的变化及其与太平洋十年涛动和厄尔尼诺南方涛动的联系。 为了实现这一目标，研究人员将结合该地区的历史记录和现代校准研究来限制对代理数据的底层解释。这项研究将有助于产生一个高分辨率的太平洋西北地区的气候历史，这将增加区域气候如何受到PDO和其他气候事件变化的影响的知识。 该研究将为研究生和本科生提供专业发展的独特体验。

This awards supports research to undertake a multi-proxy study of finely laminated lake sediments in the north central region of Washington. The researchers will investigate the complex relationships between large-scale climatic forcing, regional climatic change, and vegetation and lake responses over the past 13,000 years, at the watershed scale, in the northeast Pacific region. The overall goal of the study is to examine shifts in the regional precipitation-evaporation balance and its connection with the Pacific Decadal Oscillation (PDO) and El Nino Southern Oscillation (ENSO). To achieve this goal, the researchers will use a combination of historical records and modern calibration studies across the region to constrain the down-core interpretations of the proxy data. This research will help produce a high-resolution climate history for the Pacific Northwest that will increase knowledge of how regional climate is influenced by changes in the PDO and other climate events. The research will provide graduate and undergraduate students with a unique experience for professional development.
