Depth distribution of methane production and oxidation in a Sphagnum peat bog

Sundh I., Nilsson M., Svensson B. H. Depth distribution of methane production and oxidation in a Sphagnum peat bog.

Tiivistelmä

The anaerobic production and potential aerobic oxidation of methane were assessed in a Sphagnum-dominated peatland in Sweden. Peat from four depths in the 0-40 cm (below the vegetation surface) layer was collected in three different plant communities. The rate measurements were made with peat slurries in flasks. The ratio between the mean production and mean oxidation activities was more than ten-fold higher in the two wetter than in the driest community. The within profiles depth distributions of methanogenic and methane-oxidizing activity were similar, showing that a particular level may act as a net source or a net sink for methane, depending on prevailing environmental conditions (primarily the oxygen distribution). The results also suggest that methane production and consumption processes can occur in anaerobic and aerobic micro-zones in very close proximity to each other. Key words: Carbon flow, methane oxidation, methane production, peatlands

Avainsanat
peatlands; Carbon flow; methane oxidation; methane production
