Activity and diversity of methane-oxidizing bacteria along a Norwegian sub-Arctic glacier forefield
Methane (CH4) is one of the most abundant greenhouse gases in the atmosphere and identification of its sources and sinks is crucial for the reliability of climate model outputs. Although CH4 production and consumption rates have been reported from a broad spectrum of environments, data obtained from...
