Changes of CH4 oxidation amount with temperature in surface sediments and water column (initial and average values).
Average value was also used during the rapid warming process from 5 to 20°C. The difference between fluxes of Tube C and B is the decrease of CH4 flux due to oxidation consumption in surface sediments, while the difference between B and A results from oxidation consumption in water column. Average values of CH4 fluxes were used during rapid warming process from 5 to 20°C. The change of decrease of CH4 flux can be interpreted as oxidation amount. Oxidation rate, which is the oxidation amount in unit time, is positively correlative to temperature due to the temperature-controlled formation process. Faster increase rate of oxidation process results in a decrease process of the total CH4 emission.
