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.

合作研究：了解整个河流网络中N循环控制的缩放主要研究者：Charles Vorosmarty（新罕布什尔州，达勒姆NH大学）合作研究者：Wil Wollheim（新罕布什尔州，达勒姆NH大学） 布鲁斯彼得森（海洋生物实验室，伍兹霍尔马） Charles Hopkinson（海洋生物实验室，伍兹霍尔MA） 迈克尔·古塞夫（科罗拉多矿业学院，戈尔登CO）在美国的郊区，人类正在迅速改变高地地表和地面沃茨的特征。在无数流域，开发大大增加了河流污染，最终转移到沿海地区，造成低氧死亡区和有害藻类大量繁殖等负面影响。人们对这些变化的性质知之甚少。这项研究的目的是更好地了解一种重要营养素氮的来源和命运。这项工作计划围绕现场过程研究和计算机建模在伊普斯维奇河，波士顿北部。由于拟议的工作重点是破译管理沿海流域营养物质来源和命运的基本过程，研究结果将有助于了解美国东北部其他地区河流系统的脆弱性。该项目将有助于解决有关土地利用变化的位置和类型如何影响污染物向敏感沿海生态系统的迁移的问题，从而有助于改善现有的环境状况。管理战略。该项目还包括本科和研究生教育部分，以培训下一代科学家和从业人员。一项推广计划旨在更好地向公民通报当地流域正在发生的变化。
