UPDATE, July 31, 2014. Stories are emerging rapidly in various media this afternoon on a likely source of a statement, mysterious hole in the permafrost in the region of Yamal, in northern Russia. This hole was discovered by a helicopter pilot in mid-July; reindeer herders reported a second hole a few days later. Eric Holthaus Slate, said there are now:
New ... (and definitive) evidence ... that the holes in Siberia were created by methane released from permafrost warming.
Evidence met the journal Nature, which published an article on its website today (July 31) with the results of Andrei Plekhanov, senior fellow at the Centre for Science Studies Salekhard Arctic, Russia, and his team. This is the team that was sent to investigate the first hole shortly after it was found. Holthaus said:
The team measured methane concentrations up to 50,000 times normal inside the crater.
The story in the journal Nature, said:
Air near the bottom of the crater contained abnormally high concentrations of methane - 9.6% - in tests at the site on July 16 ... Plekhanov, who led an expedition to the crater, said the air normally contains 0.000179% methane ...
Plekhanov and his team believe is linked to unusually hot summers Yamal 2012 and 2013, which were warmer than normal in an average of about 5 ° C. When the temperature increases, the researchers suggest, thawing permafrost and s is collapsed, releasing methane that was trapped in the frozen ground.
Holthaus said:
Last week, the New York Times Andrew Revkin interviewed a Russian scientist who had also visited the hole and reached similar conclusions.
This evidence is shown just coming to light today, seems particularly scary because the story earlier this week that the University of Stockholm called "large plumes of methane" found by scientists aboard icebreaker Oden, which is studying and measuring the release of methane from the floor of the Arctic Ocean.
The Moscow Times reported this week that the reindeer herders of the extreme northern Russia have discovered Second Hole mysterious giant. According to these unconfirmed reports, the second hole is about 30 kilometers (20 miles) from the first large and mysterious hole in the permafrost of Russia, who made a splash in social networks after Siberia Times reported the mid-July 2014.
Last week, Russian scientists believe that the first hole, which has smooth sides and a lake on the bottom in about 30 to 60 meters wide (100 to 200 ft) wide. The second crater is said to be smaller than the first, about 15 meters (50 feet) wide, and is reported to be full of snow.
The two craters (assuming both exist) are in the permafrost of the Yamal-Nenets (YNAO) Russian Arctic. Moscow Times said the two craters appear to have formed relatively recently.
In fact, according to the Russian website Behind the headlines, the time of formation of the second crater could be known in the reports for the reindeer herders of the past year. . This site said the second crater may have formed in September 2013 Russia Behind the headlines, said:
New crater was renewed by local reindeer herders, who said that a celestial body fell, and then a flash took place September 27, 2013, in this region (56 km from the village of Antipayut).
A different reindeer breeder he just said you saw smoke, mist, then a flash.
Moscow and Russia time behind the headlines seem to favor the idea that the mysterious holes in the permafrost due to geophysical processes related to global warming. Russia Behind the headlines, said:
Strange holes on Earth found in northern tundra in the territory of Russia in July could mean the beginning of irreversible changes in the climate of our planet. According to Russian scientists, most likely for the formation of these holes is due to the issue of natural gas, which can be caused by global warming ...
Research and study unit subarctic in Tyumen glaciologists believe that permafrost temperatures are steadily increasing in the region Bovanenkovskoye gas field on the Yamal Peninsula in the Russian Arctic, near where I was discovered first hole. Forty years ago, on average, about eight degrees below zero, but now only three parts.
Moscow Times said:
The scientists who examined the first hole of the theory that might have been created when a mixture of water, salt and underground gas exploded ...
The region, which has one of the richest deposits of natural gas from Russia, was covered by the sea it some 10,000 years ago, and large deposits of salt left.
Moscow Times added:
Global warming is causing an alarming low melting ice in the soil, releasing gas causing an effect like the beginning of a champagne cork.
In short: A second mysterious crater found in the Yamal region in the north of Russia, according to press reports.
