Wetland ecosystems are the largest natural source of methane, a potent and long lasting greenhouse gas, to the atmosphere. Wetland soils in northern latitudes are warming faster than those in temperate and tropical regions. An understanding of the influence and feedback that these northern wetland ecosystems play in the present and future climate is needed. Accomplishing this may only be done through linking newly developed technologies that measure and quantify the processes of methane emissions on a local scale with modeling efforts that scale from local studies to the region and continent. This project will collect new measurements and leverage long-term existing data on methane emissions from five well-studied research sites that span four northern climate zones. In addition, the project will use environmental and climate variables developed from remote sensing data collected by several satellites over vast areas of the far north. Using a unique scaling approach, the emissions from northern wetlands will be determined so that a global analysis can be performed. This project will implement new measurement technologies and enable more accurate representation of methane emissions on a global scale.In addition to the scientific impacts of this project, it will also provide professional development opportunities for both undergraduate students and postdoctoral researchers. These postdoctoral researchers will grow, not only as interdisciplinary scientists, but also as mentors and engaged community partners. Through a series of opportunities, the postdoctoral researchers will develop research, communication, leadership and mentoring skills. A partnership with the Northern Ecosystems Research for Undergraduates program (an NSF REU site) will enable the postdoctoral researchers to mentor two undergraduates in summer research experiences, under the guidance of the program director.

湿地生态系统是向大气排放甲烷的最大天然来源，甲烷是一种强效且持久的温室气体。北纬地区湿地土壤的变暖速度比温带和热带地区的湿地土壤要快。需要了解这些北部湿地生态系统在当前和未来气候中所发挥的影响和反馈。要实现这一目标，只能通过将新开发的测量和量化当地规模甲烷排放过程的技术与从当地研究扩展到该地区和大陆的建模工作相结合来实现。该项目将收集新的测量数据，并利用来自跨越四个北部气候区的五个经过充分研究的研究地点的长期现有甲烷排放数据。此外，该项目将使用根据远北广大地区的几颗卫星收集的遥感数据开发的环境和气候变量。使用独特的缩放方法，将确定北部湿地的排放量，以便进行全球分析。该项目将实施新的测量技术，并能够更准确地表示全球范围内的甲烷排放量。除了该项目的科学影响外，它还将为本科生和博士后研究人员提供专业发展机会。这些博士后研究人员不仅将成长为跨学科科学家，还将成长为导师和积极参与的社区合作伙伴。通过一系列的机会，博士后研究人员将培养研究、沟通、领导和指导技能。与北方生态系统本科生项目（NSF REU 网站）的合作将使博士后研究人员能够在项目主任的指导下指导两名本科生进行夏季研究经历。
