Raised bogs are the key source of methane in West Siberia terrestrial seeps ...
The expansive plains of western Siberia contain globally significant carbon stocks, with the largest peatland complex in the world overlying the planet’s largest known hydrocarbon basin. Numerous terrestrial methane seeps have been recently discovered on this landscape, located along the Ob and Irty...
