Northern wetlands are one of the most important sources of atmospheric methane,a potent greenhouse gas with about 20 times the global warming potential of carbon dioxide. Although snow can cover the surface of northern wetlands for more than half the year,most attention has been given to methane emission from wetlands during the growing season. Here I review studies that have addressed the microbial methane production, methane oxidation,and gas transfer processes in both wetland soils and the overlaying snow cover to understand the processes of winter methane emission from northern wetlands. I emphasize,based on the findings of those studies, that there is a need for a great deal of intensive and extensive monitoring of methane dynamics in snow-covered wetlands in northern ecosystems.
