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
Novaya Zemlya Oblast, Russia. Municipally, it is incorporated as Novaya Zemlya Urban Okrug. The population of Novaya Zemlya, as of the 2010 Census, was about 2,429, of which 1,972 resided in Belushya Guba, an urban-type settlement that is the administrative center of Novaya Zemlya District. The indigenous population (from 1872 to the 1950s when it was resettled to the mainland) consisted of about 50–300 Nenetses who subsisted mainly on fishing, trapping, reindeer herding, polar bear hunting and seal hunting. Natural resources include copper, lead, and zinc. Novaya Zemlya was a sensitive military area during the Cold War years, and parts of it
