Measurement of methane fluxes from terrestrial landscapes using static, non-steady state enclosures. Chapter 12

Abstract

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.
