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.

在新罕布什尔州怀特山脉的哈伯德溪谷，降水、溪流和湖水的综合化学是世界上最长的连续记录（45年）。拟议中的研究将把这一独特的记录延长到50年甚至更长时间。本研究的主要目的是将这些长期数据应用于与北方阔叶林及其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对诸如酸雨、森林采伐、冰或风暴破坏、道路除冰剂造成的地表水盐碱化以及试验性流域生态系统操纵等干扰的反应和恢复。酸雨是在北美的哈伯德布鲁克被发现的，是一个严重的、持续的环境问题。这种精心记录的高质量长期数据对于寻求解决重大和持久环境问题的决策者至关重要。从这些长期研究中可以得知，干扰的遗留问题，如森林砍伐，持续时间超过40年。这项长期研究的一个更大的目标是帮助改变人们看待和评价流域重要性的方式，以及在日常生活中经过这些流域的地表水和空气的质量。研究人员将与公众、教育工作者和政策制定者分享该项目的长期数据，并协助他们进行解释和评估。
