Methane Content and Emission in the Permafrost Landscapes of Western Yamal, Russian Arctic
We present the results of studies of the methane content in soils of the active layer and underlying permafrost, as well as data on the emission of methane into the atmosphere in the dominant landscapes of typical tundra of the western coast of the Yamal Peninsula. A detailed landscape map of the st...
