Methanogenesis and methane oxidation were studied in the sediments of 6 Alaskan arctic lakes during the 2010 and 2011 thaw seasons. Rates of methane production were significantly higher in shallow than in deep lake types, varying from 848 to 21791 μmol m-2 d-1 and were correlated to sedimentation ra...
