B43J:
Natural Wetlands and Open Waters in the Global Methane Cycle: Modeling, Observations, and Challenges II


Session ID#: 8296

Session Description:
Natural wetlands/open waters—the world's largest, climate-sensitive methane source—are contributors to interannual and decadal fluctuations in atmospheric CH4 concentrations. Uncertainties in CH4 dynamics in wetlands derive from heterogeneity in vegetation, microtopography, permafrost condition, hydrology, and processes governing CH4 production, oxidation, and emission. Understanding and modeling CH4 dynamics and distributions of wetlands/open waters is crucial to simulating methane dynamics and feedbacks between wetlands and past, present and future climates. 

We invite presentations addressing: global-to-regional modeling CH4 dynamics in wetlands and open waters; inverse- and climate-chemistry modeling of wetland-methane dynamics; process studies of CHproduction, oxidation and emission; modeling of wetland distributions; synthesis studies of CH4 fluxes and controlling variables; remote sensing of hydrologic dynamics and vegetation characterization of wetlands; role of wetlands and water bodies in the global CH4 cycle through time. We welcome submissions identifying challenges to quantifying the role of wetlands/open waters in the global methane budget.
