Modern and Holocene Limnological Response to Climatic Gradients at the Western Edge of the Greenland Ice Sheet

该奖项是为了测试利用硅藻推断的电导率作为格陵兰冰盖西部邻近湖泊P-E(降水减去蒸散)波动的替代指标的研究。如果强大，调查员将能够重建西格陵兰沿海地区亚世纪尺度的全新世水文历史，这反过来又有助于评估这一时间框架内对海洋和陆地系统的水文影响。将通过对古海岸线的地貌研究来评估全新世期间P-E的较大尺度变化。这项研究将利用湖泊沉积物中的生物和地球化学指标，重建西格陵兰三个地区近百年尺度的全新世环境历史。

This award is for a study to test the use of diatom-inferred conductivity as a proxy for fluctuations in P - E (precipitation minus evapotranspiration) for lakes adjacent to the western portion of the Greenland Ice Sheet. If robust, the investigator will be able to reconstruct the Holocene hydrologic history of a coastal region of West Greenland at sub-century scale, which in turn can contribute to evaluating hydrologic influences on marine and terrestrial systems over this time frame. Evaluation of coarser scale changes in P - E during the Holocene will be made from geomorphic studies of paleoshorelines. The study will use biological and geochemical proxies in lake sediments to reconstruct Holocene environmental history of three local regions of West Greenland at sub-centennial scale.
