项目摘要
Although inland waters comprise only ~1% of Earth’s surface, they play a central role in the global carbon cycle. Large amounts of carbon are delivered to inland waters as terrestrial dissolved organic matter (DOM) in headwater streams. The type and amount of DOM in these streams controls whether that carbon is released to the atmosphere (i.e. stream respiration) or removed from the carbon cycle (i.e. transported downstream and buried). This project will determine the role of forest harvesting, and specifically clear cutting, in controlling carbon cycling and stream respiration in headwater streams. The results from this project will be used to develop predictive models that guide future research and inform management of forested headwater systems. This project will provide training for at least 2 PhD and 9 undergraduate student researchers who will gain interdisciplinary expertise in the hydrologic and biogeochemical sciences, solving problems of societal concern. Data and understanding gained in this project will be used as university class examples to discuss the linkages between land management, carbon cycling, and hydrologic response of forested ecosystems. This project will develop educational materials on watershed science that will reach nearly 6,000 K-12 students, 48 science teachers, and 40 pre-service students to enhance understanding of land cover-ecosystem interactions and knowledge of their local watersheds.Inland waters have recently been highlighted for their importance in global carbon pools and fluxes relative to terrestrial and marine systems. Dissolved organic matter (DOM) represents the largest fraction of organic carbon transported through stream networks, and much of this DOM enters streams in headwater forest locations. This project answers the call to ‘focus on better identifying human impacts on the transport and biogeochemical cycling of carbon by inland waters’ as outlined in the Second State of the Carbon Cycle Report, by: 1) Determining the role of forest harvesting in regulating DOM character in headwater streams; 2) Quantifying the influence of DOM character on stream ecosystem respiration; and 3) Identifying how components 1 and 2 interact to regulate spatial and temporal patterns of ecosystem respiration across forested headwater stream networks. This information will be used to create predictions that will then be confronted with data to improve models, and expose gaps in understanding to guide future field and lab experimentation. This project will develop a vertically integrated program of mentorship, education, and provide training for undergraduate and PhD students who will gain exposure to research, outreach, and professional development activities. Through collaboration with the College of Natural Science Education and Outreach Center, this project will develop a STEM kit on watershed science specifically targeted at K-12 schools with a high percentage of underrepresented students, and encourage these groups to pursue STEM pathways.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.
尽管内陆水域仅占地球表面的约1%,但它们在全球碳循环中起着核心作用。大量碳被作为雷达特流中的陆地溶解有机物(DOM)传递到内陆水域。这些流中的DOM的类型和数量控制着该碳是被释放到大气(即流呼吸)还是从碳循环(即下游和建造的运输)中去除的。该项目将确定森林收获,特别是清晰切割的作用,在控制脑水中的碳循环和溪流呼吸中的作用。该项目的结果将用于开发预测模型,以指导未来的研究并告知森林源头系统的管理。该项目将为至少2个博士学位和9名本科生研究人员提供培训,他们将获得水文和生物地球化学科学方面的跨学科专业知识,从而解决社会问题。该项目中获得的数据和理解将被用作大学班级示例,讨论森林生态系统的土地管理,碳循环和水文反应之间的联系。该项目将开发有关流域科学的教育材料,这些材料将吸引近6,000名K-12学生,48位科学老师和40名职前学生,以增强对土地覆盖生态系统互动的了解以及对当地流域的了解。溶解的有机物(DOM)代表了通过溪流网络传输的有机碳的最大部分,并且大部分DOM进入源泉的溪流。该项目回答了“专注于更好地识别人类对内陆水域对碳的运输和生物地球化学循环的影响,如碳循环报告的第二个状态所述,作者:1)确定森林收获在调节脑海中调节DOM特征的作用; 2)量化DOM特征对流生态系统呼吸的影响; 3)确定组件1和2如何相互作用以调节跨森林源头水流网络的生态系统呼吸的空间和临时模式。这些信息将用于创建预测,然后将面对数据以改善模型,并在理解中揭示差距,以指导未来的领域和实验室实验。该项目将制定一个垂直整合的心态,教育计划,并为将获得研究,外展和专业发展活动的本科生和博士学位学生提供培训。通过与自然科学教育和外展中心的合作,该项目将开发出针对具有代表性不足的学生比例高的K-12学校的流域科学套件,并鼓励这些团体追求STEM途径。该奖项反映了NSF的法定任务,并通过使用基金会的智力评估来进行评估,以评估良好的评估。
