This research will enable anyone with internet access to compare the flow and the chemistry of hundreds of streams throughout the United States and to explore their watersheds. The project will combine data sets from many separate research projects into an attractive Web site that makes the data available. This will make it easy for scientists and students to ask questions about water quality and river flow patterns across the continent. Researchers will use these data to study what types of watersheds are best at retaining nutrients, are recovering most rapidly from decades of acid rain, have the highest erosion rates, and have flow patterns that are least sensitive to floods and droughts. The lessons we learn from studying many watersheds and streams will contribute to more effective management of our nation's water and forest resources.Much of the literature of watershed ecosystem science over the last decade has focused on gaining ever finer detail of spatial heterogeneity within watersheds. This fine-scale focus has identified many idiosyncrasies of individual watersheds but has not helped us develop general theories about watershed dynamics. Most watershed ecosystem studies remain rather parochial, involving detailed studies of individual or paired watersheds, or surveys of a small set of attributes across multiple watersheds. Macrosystem watershed science, or the search for general principles that describe the functional capacity and behavior across watersheds, has been limited. A major reason for this lack of large-scale focus is the challenge of data access and integration across sites. Our goal in this proposal is to create a synthetic dataset that merges all US watershed ecosystem studies into a common platform (MacroSheds) and to enable and train a new generation of watershed ecosystem scientists in the art and practice of macroscale watershed ecosystem science.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.

这项研究将使任何有互联网访问的人都可以比较美国各地数百个流的流量和化学反应，并探索他们的流域。该项目将将来自许多独立研究项目的数据集结合到一个有吸引力的网站，以使数据可用。这将使科学家和学生可以轻松地提出有关整个非洲大陆水质和河流流程模式的问题。研究人员将使用这些数据来研究哪些类型的流域最能保留营养，从数十年的酸雨中恢复最快，侵蚀速率最高，并且对洪水和干旱敏感的流动模式最少。我们从研究许多流域和溪流中学到的教训将有助于对国家水和森林资源的更有效管理。在过去的十年中，流域生态系统科学的文献介绍了侧重于获得流域内空间异质性的细节。这种精细的焦点已经确定了各个流域的许多特质，但并没有帮助我们发展有关流域动态的一般理论。大多数流域生态系统研究仍然相当狭och，涉及对个体或配对流域的详细研究，或对多个流域跨越一系列属性的调查。宏观系统流域科学，或者寻找描述整个流域功能能力和行为的一般原则的搜索是有限的。缺乏大规模重点的主要原因是跨站点的数据访问和集成的挑战。我们在这项建议中的目标是创建一个合成数据集，该数据集将我们所有分水岭的生态系统研究合并为一个共同的平台（宏观摩擦式），并启用和培训新一代的分水岭生态系统科学家在宏观科学的艺术和实践中，在宏观阶级的生态系统上，该奖项通过Infortial Indernitory of Deem of Deem of deem evaler of Nector of deem ofer te eyme the Inderiam taperial of deem tauntorial of deem，影响审查标准。
