Lake EAST? To — The largest subglacial lake in Antarctica.
Lake Vostok is unique primarily because, perhaps, was isolated from the Earth's surface for several million years.
The opening of the East Lake — one of the largest geographical discoveries of the second half of the XX century.
- Cold pole of the planet
Drilling began in 1989 by researchers of the joint expedition of Soviet, American and French scientists.
Drilling in 1999 was conducted to a depth of 3623 m.Obraztsy ice age had this depth of about 430 thousand years, so it is assumed that the lake was clogged with ice at least 500 thousand years ago.
Between 1996 and 2006, drilling was halted due to concerns about the methods used drilling. They had to put it mildly, "environmentally unfriendly".
But in 2003, the St. Petersburg Mining Institute has developed a new 'green' technology, and in 2006 work on the deep drilling was resumed.
The work generates a lot of challenges: breaking down Burevoy equipment just stayed work, etc. Researchers have tried to be "megaostorozhnymi" afraid to break the existing ecosystem for the millennium.
But when it all comes to an end and ….
February 5, 2012, at a depth of 3769.3 meters, scientists completed drilling and reached the surface of the subglacial lake
Frozen to drill to lake water delivered to the Laboratory of Genetics PIYaF. There she studied and zayaili that were found bacteria kotorey had previously been in the drilling fluid, the lake water is mixed with a drill. Concluded that in snow and lake ice all lifeless. Sostvenno now turn to the very lake water.
The next stage, the penetration into the lake with his research instruments will only happen in 2013-2014.
Ice samples from a depth of 3623 meters were aged about 430 million years old, so it is assumed that the lake was clogged with ice at least 500 thousand years ago. The scientists hope that the microbes live there.
In conclusion, on the other hand I want to wish every success to researchers.
I hope they do not find it "Godzilla."
