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.

湿地生态系统是甲烷的最大自然来源，一种有效且持久的温室气体，它可以到达大气中。北纬度地区的湿地土壤比温带和热带地区的湿地变暖更快。需要了解这些北部湿地生态系统在当前和未来气候中发挥的影响和反馈。实现这一目标只能通过连接新开发的技术来实现，该技术通过在本地规模上测量和量化甲烷排放的过程，并通过建模工作从当地研究到该地区和大陆进行建模工作。该项目将收集新的测量结果，并利用五个跨越北部气候区域的五个经过良好研究地点的甲烷排放的现有数据。此外，该项目将使用来自遥远北部广阔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，以便可以进行全球分析。该项目将实施新的测量技术，并在全球范围内更准确地表示甲烷排放。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的机会。这些博士后研究人员将不仅作为跨学科科学家，而且作为导师和敬业的社区伙伴而成长。通过一系列机会，博士后研究人员将发展研究，沟通，领导和指导技能。在该计划主管的指导下，与北部生态系统研究（NSF REU站点）的合作关系（NSF REU站点）将使博士后研究人员能够在夏季研究经验中指导两名本科生。
