Yamal Peninsula


The Yamal Peninsula is located in the Yamalo-Nenets Autonomous Okrug of northwest Siberia, Russia. It extends roughly 700 km and is bordered principally by the Kara Sea, Baydaratskaya Bay on the west, and by the Gulf of Ob on the east. At the northern end of this peninsula lie the Malygina Strait and, beyond it, Bely Island. In the language of its indigenous inhabitants, the Nenets, "Yamal" means "End of the Land".

History

The peninsula consists mostly of permafrost ground and is geologically a very young place —some areas are less than ten thousand years old.
Yamal is inhabited by a multitude of migratory bird species.
The well-preserved remains of Lyuba, a 37,000-year-old mammoth calf, were found by a reindeer herder on the peninsula in the summer of 2007. The animal was female and was determined to be one month old at the time of death.
On 21 October 2016 a Russian Mi-8 helicopter carrying oil and gas workers crashed there, killing at least 19 of the 22 people on board.

Reindeer husbandry

According to Sven Haakanson, within the Russian Federation, the Yamal peninsula is the place where traditional large-scale nomadic reindeer husbandry is best preserved. Nenets and Khanty reindeer herders hold about half a million domestic reindeer.

Development

The area is largely undeveloped, but work is ongoing with several large infrastructure projects, including a gas pipeline and several bridges. Yamal holds Russia's biggest natural gas reserves. The 572 km Obskaya–Bovanenkovo railway, completed in 2011, is the northernmost railway in the world. Russian gas monopolist Gazprom had planned to develop the Yurkharovskoye gas field by 2011–2012. The peninsula's gas reserves are estimated to be 55 trillion cubic meters. Russia's largest energy project in history, known as the Yamal project, puts the future of nomadic reindeer herding at considerable risk.

Yamal craters

In 2014, Yamal was the discovery site of a distinct sinkhole, or pingo, which quickly drew the attention of world media. The sinkhole appeared to be the result of a huge explosion and several hypotheses were suggested to explain the formation of the crater, including a hit by a meteorite or a UFO, or the collapse of an underground gas facility.
A spokesperson for the Yamal branch of the Emergencies Ministry said, "We can definitely say that it’s not a meteorite."
The 60-meter crater is believed by a senior researcher from the Scientific Research Center of the Arctic, Andrei Plekhanov, in remarks to the Associated Press, to be likely the result of a "buildup of excessive pressure" underground because of warming regional temperatures in that portion of Siberia. Tests conducted by Plekhanov's team showed unusually high concentrations of methane near the bottom of the sinkhole.
The destabilization of gas hydrates containing huge amounts of methane gas are believed to have caused the craters on the Yamal Peninsula.
As of 2015, the Yamal peninsula had at least five similar craters.

Offshore methane leaks

According to researchers at Norway's , 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 is leaking in an area of at least 7500 m2. In some areas gas flares extend up to. Prior to their research it was proposed that methane was tightly sealed into the permafrost by water depths up to. Close to the shore however, where the permafrost seal tapers to a depth of as little as, there are significant amounts of gas leakage.
