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
Cape Berg Cape Berg Cape Berg (, "Mys Berga") is a headland in Severnaya Zemlya, Russia. This cape was named after prominent Soviet geographer and biologist Lev Berg (1876 – 1950). Stretching out towards the Laptev Sea east of the Rusanov Glacier, Cape Berg is the northeasternmost point of October Revolution Island. The shore of present-day Severnaya Zemlya was discovered by Boris Vilkitsky in 1913 during the Arctic Ocean Hydrographic Expedition on behalf of the Russian Hydrographic Service. On 3 September 1913 —22 August 1913 in the Julian calendar used by Russia at the time, members of the expedition went to the
