Abstract

Methane in muddy waters Submarine mud volcanoes may be major players in the emission of the greenhouse gas methane. A select group of microorganisms, called methanotrophs, can consume this gas, but their impact on methane emission in this environment is not well understood. A study of the waters around a mud volcano in the Barents Sea has identified three key methanotrophic communities: aerobic bacteria, anaerobic archaea living beneath tubeworms, and previously undescribed archaea associated with bacterial mats. A natural cap on the capacity of the microbial methane filter was also discovered: the upward flow of sulphate- and oxygen-free volcanic fluids restricts the efficiency of methane oxidation, allowing much of the methane to escape to the hydrosphere and potentially the atmosphere.
