CH4 flux under different temperatures in Tube A, B and C.
Tube A, B and C are experimental controls. CH4 fluxes in Tube A, B and C simulate CH4 formation with oxidation consumption of surface sediments and water column, CH4 formation only with oxidation consumption of surface sediments and CH4 formation process without aerobic oxidation, respectively. CH4 flux didn't increase continuously during the rapid warming process except Tube C from 20 to 30°C, while it decreased continuously during the rapid natural cooling processes in all tubes. When the temperature remained constant, CH4 flux in each tube is fluctuating around a certain value.
