Methane oxidizing microbial communities in open-system pingo methane seeps

Open system pingos are permafrost features found in the Arctic, many of which are outlets for sub-permafrost groundwater that can carry substantial amounts of methane (CH4). We study the microorganisms in this water and the surrounding surface area to identify how the CHwas produced and the capacity of aerobic and anaerobic CHoxidizing microorganisms for consuming the CH4.
