Measurement of Methane Fluxes from Terrestrial Landscapes Using Static, Non-steady State Enclosures

Wetlands are a dominant natural source of atmospheric methane (CH4), a potent greenhouse gas whose concentration in the atmosphere has doubled over the past 150 years. Evaluating the impacts of CH4 emissions on global climate and developing policies to mitigate those impacts requires a quantifiable and predictive understanding of natural CH4 processing. Developing field sampling campaigns that quantify CH4 flux in landscapes with prominent wetland features is a vital first step to developing that understanding. This chapter describes a field sampling approach that relies on static chambers to capture the CH4 emitted from saturated soils and laboratory analyses of sequential samples to quantify CH4 fluxes. Ultimately, by relating CH4 fluxes from intensively sampled field sites to more easily measured ecosystem properties (e.g., temperature, water table, and productivity), models may be developed to predict CH4 fluxes at larger landscape and regional scales.
