Short summary
We assessed the importance of aerobic CH4 oxidation in Alaskan lakes. We conducted field measurement of dissolved CH4 and O2 together with determination of the CH4 oxidation rate. We found that during winter, CH4 oxidation was limited by O2 concentration and during summer, by CH4 concentration. In addition to seasonal variations, the type of permafrost on which the lakes were located was identified as a key factor, indicating that landscape processes play an important role in lake CH4 cycling.
