Session ID#: 13715

Session Description:
Natural wetlands and open waters (lakes, rivers, reservoirs) are major, climate-sensitive methane (CH4) sources. Uncertainties in CH4 dynamics in these landscapes derive from heterogeneity in vegetation, microtopography, permafrost, hydrology, and CH4 production, oxidation, and emission. The sign and magnitude of responses of wetland and open-water distributions and emissions under warming climate are uncertain. Understanding and modeling the distribution and CH4 dynamics of these heterogeneous ecosystems is crucial to predicting biogeochemical dynamics under past, present and future climates. We invite studies of global-to-regional modeling of CH4 dynamics in wetlands and open waters; satellite assessment of CH4 emissions; role of wetlands and open waters in the global CH4 cycle under past/future climates; synthesis studies of CH4 fluxes and controlling variables; remote sensing of hydrologic dynamics and vegetation in wetlands and open waters; process studies including multiple sampling approaches (i.e. isotopes, metagenomics, modeling) of CH4 production, oxidation and emission; modeling of wetland distributions.
