Session B09: Remote Sensing and Modeling of Hydrologic and Methane
Dynamics in Natural Wetlands

Session description:
Natural wetlands, comprising saturated and flooded environments
associated with rivers, lakes, high water tables, and poorly-drained
permafrost, dominate the global methane cycle through their sensitivity
to interannual and longer-term climate fluctuations. They account for
approximately 30 percent of global methane emissions each year, and are
identified as the primary contributor to interannual variations in the
growth rate of atmospheric methane concentrations. Despite their
importance to current and future climate via their role in the global
carbon/methane cycle, natural wetlands remain poorly characterized and
modeled due primarily to the scarcity of suitable regional-to-global
remote-sensing data and techniques for characterizing their distribution
and dynamics. Moreover, because wetland dynamics are driven by complex
interactions among a suite of thermal and hydrological variables,
predictions of the distribution and functioning of wetlands under future
climate regimes remain highly uncertain.

Session conveners welcome submissions on regional, continental, and
global scales related to 1) remote sensing of wetland vegetation and
hydrology, 2) hydrological and methane modeling of wetlands using Global
Climate Models (GCMs), as well as in inverse, ecosystem, and other
models, and 3) modeling of wetland dynamics under future climate change.

Abstracts must be submitted by Thursday, 1 March 2007, at the conference
