Estimation of methane and carbon dioxide surface fluxes using a 3-D global atmospheric chemical transport model
Methane (CH₄) and carbon dioxide (CO₂) are the two most radiatively important greenhouse gases attributable to human activity. Large uncertainties in their source and sink magnitudes currently exist. We estimate global methane surface emissions between 1996 and 2001, using a top-down approach that …

Methane Fluxes from Living and Dead Trees in a Temperate Forest
… have been identified as an important source of methane in forest ecosystems, but little research exists on fluxes beyond their stems, such as those from foliage, branches, wounds, and coarse woody debris. Recent instrumentation advances allow rapid and accurate measurements of relatively low …

Biogeochemical investigations of methane-rich groundwaters in high Arctic glacial catchments
… a potentially large reservoir of sub-surface methane and prevents it from reaching the atmosphere. The vulnerability of the cryosphere to climate warming is making releases of this methane possible, but uncertainty in the magnitude and timing of such releases makes predictions of Arctic …

Patterns, Processes And Models Of Microbial Recovery In A Chronosequence Following Reforestation Of Reclaimed Mine Soils
… lower relative abundances of methanotrophs and methane monooxygenase at previously-mined sites compared with unmined sites, which supports previous observations that ecological function of methane sink provided by many forest soils has not recovered after 30 years. Because of the difficulty …
