Russian polar explorers resumed drilling on the lake


Employees glaciological-drilling team in the new year to resume drilling wells above the relict Lake Vostok in Antarctica, said the head of the Russian Antarctic Expedition (RAE) of the Arctic and Antarctic Research Institute of Hydromet (AARI), Valery Lukin.

In early February 2012 drilling team specialists of the 57th Russian Antarctic Expedition after decades of drilling for the first time entered into hidden under the Antarctic ice thickness chetyrehkilometrovoy East Lake — the largest subglacial lake in Antarctica. Analysis of water samples East first showed that they practically do not contain microorganisms.

"Drilling wells goes according to plan, no failures and no accidents. As far as I know, they have not yet reached a new core formed from lake water that rose in the well. As I recall, last week they were at around 3295 meters ", — said Lukin, without specifying the date of the beginning of drilling.

Drilling operations on the well conducted as part of the 58th Russian Antarctic Expedition (RAE). In early December last year, there officers arrived and drilling team began preparations for the reopening of the well. Drilling and lifting fresh frozen water relict lake is expected to leave all this season.

As previously reported, the depth of the well is approximately 3769.3 meters. It was at that point in the past, there was a contact of the bit with the water lens of the lake. After the drill was raised, the water from the lake, thanks to the pressure rose and frozen in the well to a height of 600 meters.

Lake Vostok in Antarctica is a unique aquatic ecosystem that has been isolated from the earth’s atmosphere and surface of the biosphere for millions of years. His study has played a huge role in the study of climate change in the last millennium.
