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.

AGU Methane – Wetland Session Announcement


6th July 2011. We invite submissions to the following AGU session focusing on natural wetlands and their methane emissions.  We encourage regional-to-global scale studies on modeling of wetlands and their methane dynamics, and remote sensing of surface inundation and wetland distribution.

The deadline for abstract submission is 4 August, 2011, 03:59 +1 GMT.

B49: Natural Wetlands: Observations and Modeling of Distributions and Methane Dynamics

Natural wetlands are the world’s largest methane source and are highly sensitive to climate variations. Uncertainties in methane emission are driven in part by the spatial and temporal heterogeneity of oxidation, production and emission processes in these ecosystems as well as by the inherent variation in vegetation and hydrologic regimes of the world’s wetlands. Understanding and integrating knowledge about wetland distributions, processes and characteristics from local field studies to regional/global scales is crucial to predicting biogeochemical and distributional dynamics under past, present and future climates. We invite abstracts for modeling and measurement studies focusing on: mechanisms of methane production, oxidation and emission; remote sensing of surface hydrological dynamics and vegetation characterization; and modeling of wetland distributions and their methane dynamics under all climates.
