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

该奖项是为了表彰一项合作实验(明尼苏达大学和爱荷华州立大学)，该实验使用耦合陆地大气模拟计划(CLAP)，将模拟的古湖泊水位和水化学与从高分辨率湖泊岩心记录推断的结果进行直接比较。这项研究将定量评估含水层系统如何影响冰川流域内的湖平面波动，方法是将CLAP应用于明尼苏达州中北部研究充分的乌翼流域，并将CLAP模型的结果与保存在湖泊沉积物中的替代记录的古气候重建进行比较。通过模拟个别湖泊和河流的水文波动，该模式将能够对区域尺度上全新世气候变化的古大气环流模式进行最全面的评估。

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.
