Abstract
Nearly all the methane oxidation occurred in the anoxic zones of the lake. Rates of anaerobic oxidation exceeded production at all depths studied in both the mixolimnion (2-6 vs. 0.1-1 nmol liter-1 d-1) and monimolimnion (49-85 vs. 1.6-12 nmol liter-1 d-1) of the lake. Thus, a net consumption of methane equivalent to 1.36 mmol m-2 d-1 occurred in the anoxic water column. Anaerobic methane oxidation had a first-order rate constant of 8.1+ or -0.5 X 10-4 d-1, but in situ methane oxidation was of insufficient magnitude to cause a noticeable decrease of ambient dissolved methane levels over an incubation period of 97h. -from Authors
