Archaea were detected in molecular diversity studies of the permanently frozen Lake Fryxell, Antarctica. Two clusters of methanogens were detected in the sediments, and another cluster of possibly methanotrophic Euryarchaeota was detected in the anoxic water column just above the sediments. One crenarchaeote was detected in water just below the oxycline. The Archaea present in Lake Fryxell are likely involved in the major biogeochemical cycles that occur there.
