Ebullition of methane‐containing gas bubbles from near‐surface Sphagnum peat

To date, very little information has been available on the build‐up and release of biogenic gas bubbles in poorly‐decomposed bog peats near the peatland surface (upper 1 m). We investigated the importance of ebullition of biogenic gas bubbles as a mechanism for the transport of CH 4 to the atmosphere in eight cores (24 cm diameter, 22 cm depth) of poorly‐decomposed, near‐surface bog peat. Ebullition was recorded in all but one sample but varied …
