Arctic methane emissions permafrost thawing. Near the bottom of the first sinkhole, air contained unusually high concentrations of methane, according to tests conducted by the researchers. This hypothesis points to the destabilization of gas hydrates containing huge amounts of methane gas. According to researchers at Norway's Centre for Arctic Gas Hydrate (CAGE), through a process called geothermal heat flux, the Siberian permafrost which extends to the seabed of the Kara Sea, a section of the Arctic Ocean between the Yamal Peninsula and Novaya Zemlya, is thawing. According to a CAGE researcher, Aleksei Portnov, Methane hydrate is leaking in an area of at least
Zemlya Georga seasonal research station which can shelter up to 10 persons. The "Nightingale Channel" (Proliv Neytingeyl) runs east of Zemlya Georga, separating it from Bruce Island. Most of the land lies under large glaciers and ice domes, such as the Brusilov Ice Dome, Gretton Ice Dome, Dzegudze Ice Dome (Купол Дзегудзе), Zander Ice Dome, Foggy Ice Dome (Купол туманный), Arctic Geology Research Institute Ice Dome (Купол Научно-исследовательский институт геологии Арктики) and the Peary Ice Dome, although there is a large, mostly unglacierized peninsula at its northern end, "Poluostrov Armitidzh".
