Northern Siberia - New giant holes found in Yamal permafrost.

Northern Siberia - New giant holes found in Yamal permafrost.(RBTH).

Scientists have discovered two huge new holes in the ground on the Yamal Peninsula in northern Siberia, adding to those identified last summer, RIA Novy Region has reported.

Moreover, a grouping of dozens of smaller holes, known to scientists as funnels, has sprung up around one of the earlier discovered craters.

Including those discovered in summer 2014, a total of four huge craters have now been found on the Yamal Peninsula. Environmentalists fear that more funnels may occur near populated areas, which could lead to disasters on a local scale.

The new craters are located approximately 10 kilometers (6.2 miles) from Bovanenkovskoye, one of the largest gas condensate fields on the planet.

According to scientists, the formation of the holes is due to emissions of gas trapped under pressure in the upper layers of permafrost. The gas escaped after microcracks appeared in the thick ice because of warming in the polar latitudes.

"I am sure that there are more craters on [the] Yamal [Peninsula], we just need to search for them... I suppose there could be 20 to 30 craters more," Prof. Vasily Bogoyavlensky, a corresponding member of the Russian Academy of Sciences and deputy director of the Moscow-based Oil and Gas Research Institute, told The Siberian Times.

Bogoyavlensky has called for urgent investigation of the new phenomenon amid safety fears. "It is important not to scare people, but to understand that it is a very serious problem and we must research this." 

Doctor of Geological and Minerological Sciences Marina Leibman (of the Earth Cryosphere Institute of the Siberian Branch of the Russian Academy of Sciences) supports this gas theory.

“For me the biggest surprise was that the location appeared untouched by any kind of human activity,” Leibman explained to RBTH early in August, commenting on the appearance of the first Yamal holes. “My first thoughts were that this hole was the result of an accident that occurred whilst drilling for natural gas.”

Scientists interviewed by RBTH confirm that the mysterious holes on the Yamal Peninsula that have sparked so much interest on the internet have no known analogues on land, but could indicate a serious degradation of the permafrost, with global implications.

High level of deadly methane bubbling to the surface of the Arctic Ocean

Dramatic and unprecedented plumes of methane – a greenhouse gas 20 times more potent than carbon dioxide – have been seen bubbling to the surface of the Arctic Ocean by scientists undertaking an extensive survey of the region.
The scale and volume of the methane release has astonished the head of the Russian research team who has been surveying the seabed of the East Siberian Arctic Shelf off northern Russia for nearly 20 years.

In an exclusive interview with The Independent, Igor Semiletov of the International Arctic Research Centre at the University of Alaska Fairbanks, who led the 8th joint US-Russia cruise of the East Siberian Arctic seas, said that he has never before witnessed the scale and force of the methane being released from beneath the Arctic seabed… Read entire article independent
