Natural Wetlands and Open Waters in the Global Methane Cycle: Modeling, Syntheses, Characterization, Observations, and Challenges

Session ID#: 75761

Session Description:
Natural wetlands and inland open waters (lakes, rivers, reservoirs) are climate-sensitive methane (CH4) sources playing a substantial role in the global CH4 budget. They are the largest natural CH4 source but substantial differences in emissions remain between bottom-up biogeochemical and Earth-System models and top-down flux estimates. In wetlands, uncertainties in CH4 dynamics derive from heterogeneity in vegetation, microtopography, permafrost, and hydrology, and from model-specific representation of wetlands and processes. The sign/magnitude of responses of wetland and open-water distributions/emissions to warming are not unequivocally determined. We invite investigations focused on reducing uncertainties and reconciling long-standing inconsistencies in wetland/open water CH4 dynamics: e.g. studies employing various sampling and evaluation approaches (i.e. isotopes, metagenomics, flux observations, modeling), linking field measurements to regional/global estimates, and investigating CH4 fluxes and controlling variables. Also welcome are remote-sensing of hydrologic dynamics and vegetation characterization, global/regional modeling of CH4 dynamics, modeling wetland distributions, and satellite assessment of emissions.
