Some northern sources of atmospheric methane: production, history, and future implications
Northern sources, including wetlands and perhaps gas hydrates, contribute significantly to the CH 4 content of the atmosphere. Methane production from northern wetlands, including bogs, swamps, and ponds, is probably very seasonal, being most important in late summer, with significant evasion in aut...

Northern sources, including wetlands and perhaps gas hydrates, contribute significantly to the CH 4 content of the atmosphere.
