Collaborative Research: Understanding the Scaling of N Cycle Controls Throughout a River Network Principal Investigator: Charles Vorosmarty (University of New Hampshire, Durham NH)Co-Investigators: Wil Wollheim (University of New Hampshire, Durham NH) Bruce Peterson (Marine Biological Laboratory, Woods Hole MA) Charles Hopkinson (Marine Biological Laboratory, Woods Hole MA) Michael Gooseff (Colorado School of Mines, Golden CO)In suburbanizing regions of the country, humans are rapidly changing the character of upland surface and ground waters. In countless watersheds, development has greatly increased riverborne pollution that ultimately passes to the coastal zone with negative impacts such as low oxygen dead zones and harmful algal blooms. The nature of these changes is poorly understood. The goal of the study is to better understand the sources and fates of one important nutrient, nitrogen. The effort is planned around field process studies and computer modeling in the Ipswich River, north of Boston. Because the proposed work focuses on deciphering the fundamental processes that govern sources and fates of nutrients in coastal watersheds, results will help to understand the vulnerability of river systems in other parts of the Northeastern U.S.A. The project will help address questions about how the location and types of land use change affect pollutant transport into sensitive coastal ecosystems and will thus help to improve existing environmental management strategies. The project also includes an undergraduate and graduate educational component to train the next generation of scientists and practitioners. An outreach program is designed to better inform citizens about the changes unfolding across their local watersheds.

协作研究：了解n个周期控制的规模在整个河网络首席研究员：查尔斯·沃罗斯马蒂（Charles Vorosmarty）（新罕布什尔大学，新罕布什尔大学，杜勒姆NH）共同投资者：威尔·沃尔海姆（Wil Wollheim）（新罕布什尔州新罕布什尔州，达勒姆NH）布鲁斯大学布鲁斯大学布鲁斯大学布鲁斯·彼得森（Bruce）布鲁斯·彼得森（Bruce Bruce Peterson）在该国郊区化地区的Golden Co）中，人类正在迅速改变高地表面和地下水的特征。在无数的分水岭中，发展大大增加了河流污染，最终带到了沿海地区，其负面影响，例如低氧死区和有害的藻华。这些变化的性质知之甚少。该研究的目的是更好地了解一种重要的营养素氮的来源和命运。这项工作是在波士顿以北的伊普斯维奇河的现场过程研究和计算机建模围绕的努力。因为拟议的工作重点是解释沿海流域中养分来源和命运的基本过程，因此结果将有助于了解美国东北部其他地区河流系统在河流系统的脆弱性。该项目将有助于解决有关土地利用的地理位置和类型的问题，从而影响污染物的危险范围内的危险沿海生态系统，从而改善了现有的策略，并改善了现有的环境，并改善了现有的环境。该项目还包括一个本科和研究生教育组成部分，以培训下一代科学家和从业者。宣传计划旨在更好地将其当地分水岭发生的变化告知公民。
