Glaciers occur in mountains across the globe. Water from melting glaciers is important to humans and other organisms. Some of this water goes directly to streams while some will flow deep into the ground and refill groundwater. It is not known how much melt-water goes directly to streams versus to groundwater. This project uses water chemistry and biological data to determine where the water goes when a glacier melts. The project examines water from glaciers on Mt. Hood in Oregon and from glaciers in Glacier National Park in Montana. This project is training graduate students and multiple undergraduate students. The results are presented at scientific meetings and to water managers. The results are also available to the public via pamphlets and news articles. More than ninety percent of the Earth's alpine glaciers are in retreat and many of these glaciers will melt completely within this century. Very little research has been conducted on the impacts of alpine glacial meltwater to recharge and flow within the mountain block. This project seeks to identify the contribution of alpine glacial meltwater to mountain recharge relative to seasonal snow and rain using chemical and biological approaches. This research tests the following hypotheses: 1) The glacial environment selects for unique biota resulting in deoxyribonucleic acid (DNA) fingerprints in alpine glacial meltwater that are distinct from seasonal snow and rain; 2) Alpine glacial meltwater is a significant source of mountain recharge and sustains perennial flow to local and regional-scale springs located down-gradient of alpine glaciers. This research assesses the novel application of DNA as a tracer for mountain recharge and increases the ability to detect recharge from alpine glaciers located in different geologic and geographic settings. This study trains graduate students and multiple undergraduate researchers and engages with water managers.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

冰川出现在全球各地的山上。冰川融化的水对人类和其他生物都很重要。其中一些水直接流入溪流，而另一些则流入地下深处，重新补充地下水。目前尚不清楚有多少融水直接流入溪流，而多少流入地下水。这个项目使用水化学和生物数据来确定冰川融化时水的去向。该项目检测了俄勒冈州胡德山冰川和蒙大拿州冰川国家公园冰川的水。本项目培养研究生和多名本科生。研究结果在科学会议和水资源管理者面前展示。调查结果也可通过小册子和新闻文章提供给公众。地球上90%以上的高山冰川正在退缩，其中许多冰川将在本世纪内完全融化。关于高山冰川融水对山地内部补给和流动的影响的研究很少。该项目旨在利用化学和生物方法确定高山冰川融水相对于季节性雪和雨对山区补给的贡献。本研究验证了以下假设：1)冰川环境对独特生物群的选择导致高山冰川融水脱氧核糖核酸（DNA）指纹与季节性雨雪不同；(2)高山冰川融水是高山补给的重要来源，常年源源不断地流向高山冰川下坡的局地和区域尺度的泉水。本研究评估了DNA作为山区补给示踪剂的新应用，并增加了探测位于不同地质和地理环境的高山冰川补给的能力。本研究培养研究生和多名本科生研究人员，并与水管理人员接触。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
