Abstract	Atmospheric methane is the second most important greenhouse gas after carbon dioxide. Carbon-rich permafrost sediments are an important source of methane. Due to the Holocene rise of the artic sea level, large areas of formerly coastal permafrost were buried under the sea, creating a submarine permafrost. In order to better understand the methane cycle in submarine permafrost, geochemical and molecular ecological studies on archaeal diversity have been carried out which particularly examine the role of methanogens. In this study frozen sediments were extracted from a 77 meter deep core in the Laptev Sea shelf, North Eastern Siberia, which have been dated to approximately 111,000 years BP.
