Research output: Contribution to conferenceAbstract


Ice currently covers approximately 10% of the Earth’s land mass, yet the role of sub-ice biomes in global biogeochemical cycles, including that of carbon, is poorly understood. Methanogenic archaea have a unique role in the global carbon cycle as producers of the greenhouse gas, methane and recent modeling studies have highlighted the potential of basal sediments of ice sheets as sources of methane during deglaciation. High concentrations of methane have been measured in the basal ice of the GRIP core from the Greenland Ice Sheet and methane-producing enrichments have been reported from John Evans Glacier, Canada; however, it is unclear whether the microbial consortia was remnant or active in situ. We discuss the role of subglacial methanogenesis in planetary carbon cycling in light of new field data.
