Lake Vostok found after Buried 20 Million Years Under the Ice
A group of researchers from Russia managed to reach the lake Vostok, buried at the base of the Antarctic ice sheet. The lake vostok has been buried at a depth of approximately 3 kilometers, for more than 14 million years.
As reported by Live Science, Thursday (02/09/2012), the achievement was obtained after drilling for decades. Tools used by scientists drilling through the ice was thin at the base of the main ice sheet, and touched the Vostok lake water at a depth of 3769 meters.
Drilling at Vostok Station began in 1970, before there was an inkling about the existence of Earth’s largest lakes on the basis of the study sites. Drill was used directly to the researchers that can only be used to take samples of ice, so to be able to obtain samples of water, they still have to wait until next season.
Scientists suspect that the giant lake inhabited by unique organisms adapted to live in the dark at the base of the ice sheet. Even if the scientists of Russia failed to find evidence of living organisms in samples from Vostok, there is still no reason to say the region is a dead zone.
Proclaimed National Geographic, John Priscu, an ecologist at Montana State University believes that ppencapaian opened the door to knowledge of the subglacial area. While Priscu himself has found evidence that microbes can live in the subglacial lake, because the energy gained from minerals by eating rocks.
“I hope they can confirm unequivocally that there is microbial life on the lake,” said Priscu.
“In the past, this has become the main argument, which can diseselaikan with real examples. If they can confirm the existence of life, this will change our view of the Antarctic,” he said.
