Effect of temperature and atmospheric pressure on methane (CH4) ebullition from near‐surface peats

Recent studies suggest that ebullition of biogenic gas bubbles is an important process of CH 4 transfer from northern peatlands into the atmosphere and, as such, needs to be better described by models of peat carbon dynamics. We develop and test a simple ebullition model in which a threshold gas volume in the peat has to be exceeded before ebullition occurs. The model assumes that the gas volume varies because of gas production and variations …
