Collaborative Research: The Role of Aquifers in Paleoclimatic Reconstructions of Glaciated Watersheds.

该奖项是为合作实验（明尼苏达大学和爱荷华州州立大学）使用耦合陆地大气模拟程序（CLASP）进行直接比较模拟古湖泊水位和水化学与那些从高分辨率湖芯记录推断。这项研究将定量评估含水层系统如何影响湖泊水位波动冰川流域内应用CLASP研究乌鸦翼流域在明尼苏达州中北部，并通过比较CLASP模型结果保存在湖泊沉积物中的代理记录的古气候重建。通过模拟个别湖泊和河流的水文波动，该模式将允许最全面的评价古大气环流模式重建全新世气候变化在区域尺度上。

This award is for a collaborative experiment (University of Minnesota and Iowa State University) using a Coupled Land Atmosphere Simulation Program (CLASP) to make direct comparisons between simulated paleo lake-levels and hydrochemistry with those inferred from high-resolution lake-core records. The study will quantitatively evaluate how aquifer systems influence lake-level fluctuations within glaciated watersheds by applying CLASP to the well studied Crow Wing watershed in north-central Minnesota and by comparing the CLASP model results to paleoclimatic reconstructions from proxy records preserved in lake sediments. By simulating the hydrologic fluctuations of individual lakes and streams, the model will permit the most comprehensive evaluation of paleo atmospheric general circulation model reconstruction of Holocene climatic change at the regional scale.
