Abstract

Water level controlled gas emissions from North Florida swamp forests. Under flooded conditions, CO2 and CH4 were the principle carbon gases transported to the atmosphere by bubble ebullition and molecular diffusion. Methane emissions were significantly attenuated by CH4 oxidation which occurred primarily at the sediment-water interface. Under dry conditions, CO2 was the principle carbon gas released and atmospheric CH4 was consumed by microbes in the soil. A carbon budget for the degradation of soil organic matter was developed for a swamp forest site under flooded and dry conditions. -from Authors
