The comprehensive chemistry of precipitation, stream and lake water within the Hubbard Brook Valley of the White Mountains of New Hampshire is the longest continuous record (45 years) of this type in the world. The proposed research would extend this unique record to 50 years and beyond. The main objective of this research is to apply these long-term data to important questions related to biogeochemical change in northern hardwood forest and associated aquatic ecosystems. For example, these long-term data will be used to quantify and evaluate the response to and recovery from disturbance such as acid rain, forest harvesting, ice or wind-storm damage, salinization of surface waters from road deicers, and experimental watershed-ecosystem manipulations. Acid rain was discovered in North America at Hubbard Brook and is a serious, ongoing environmental problem. Such carefully documented, high-quality long-term data are crucial to decision-makers searching for solutions to major and persistent environmental problems. It is known from these long-term studies that legacies of disturbance, such as from forest cutting, last longer than 40 years. A larger goal of this long-term research is to help transform the way people view and value the importance of watersheds and the quality of surface waters and air passing over these watersheds in their daily lives. Researchers will share the long-term data from this project with the public, educators and policy makers and assist with their interpretation and evaluation.

新罕布什尔州怀特山脉哈伯德溪谷内降水，溪流和湖水的综合化学反应是世界上这种类型的最长连续记录（45年）。 拟议的研究将这一独特的记录扩展到50年及以后。 这项研究的主要目的是将这些长期数据应用于与北部硬木森林和相关水生生态系统的生物地球化学变化有关的重要问题。 例如，这些长期数据将用于量化和评估诸如酸雨，森林收获，冰或风向损害等干扰的反应和恢复，道路deicers的地表水和实验性水域生态系统操作。 在哈伯德·布鲁克（Hubbard Brook）的北美发现了酸雨，这是一个严重的，正在进行的环境问题。 这种经过仔细的记录，高质量的长期数据对于寻找解决重大和持续环境问题的解决方案的决策者至关重要。 从这些长期研究中可以知道，诸如森林切割之类的障碍持续超过40年。 这项长期研究的更大目标是帮助人们改变人们对流域的重要性以及地表水和空气在日常生活中经过这些分水岭的质量的方式。 研究人员将与公众，教育者和政策制定者分享该项目的长期数据，并协助他们的解释和评估。
