American Geophysical Union, Fall Meeting, 15-19 December 2014, San Francisco


5th July 2014.

We invite abstract submissions to Natural Wetlands and Open Waters in the Global Methane Cycle:

Abstract deadline: 6 August 2014

Description: Natural wetlands and open waters (lakes, ponds, streams, reservoirs) are major, climate-sensitive methane (CH4) sources. Uncertainties in CH4 dynamics from these landscapes derive from heterogeneity in vegetation, microtopography, permafrost, hydrology, and CH4 production and emission. Sign and magnitude of responses of wetland and open-water distributions and their emissions under warming climate are uncertain. Understanding and modeling distributions and CH4 dynamics of these heterogenous ecosystems is crucial to predicting biogeochemical and distributional dynamics under past, present and future climates.

We invite studies on: global-to-regional modeling of CHdynamics in wetlands and open waters; modeling of wetland and open-water distributions; airborne and space-borne assessment of CHemissions; role of wetlands and/or water bodies in the global CHcycle under past and future climates; synthesis studies of CHfluxes and controlling variables; remote sensing of hydrologic dynamics and vegetation characterization in wetlands and open waters; process studies of CHproduction, oxidation and emission.
