Antarctica: The Final Frontier?   Leave a comment

Moscow, January 5 2012: A Russian team has succeeded in drilling through four kilometres (2.5 miles) of ice to the surface of a mythical subglacial Antarctic lake which could hold as yet unknown life forms.

Lake Vostok is the largest subglacial lake in Antarctica and scientists want to study its eco-system which has been isolated for hundreds of thousands of years under the ice in the hope of finding previously unknown microbiological life forms.

Sergei Lesenkov, spokesman for the Arctic and Antarctic Scientific Research Institute, told AFP in Moscow that there was the possibility of a “fundamental scientific development”.

Lesenkov said that analysis of the composition of gas bubbles discovered in the ice above the lake could help climate change research.

“Because the lower layer was formed 400,000 years ago, from the composition of the gas it is possible to judge the gas composition in the atmosphere 400,000 years ago and during the time that has passed since the formation of the lake,” he said.

“From there, it is possible to identify and forecast certain climatic changes in the future. This is very important.”

No official announcement of the breakthrough has been made, although sources said that this was expected to come from the government.

“If it is true and it’s successful, it’s a milestone that’s been completed. This is a major achievement for the Russians because they’ve been working on it for years,” Professor Martin Siegert, head of the school of geosciences at the University of Edinburgh, told AFP.

He said that exploring environments such as Lake Vostok would allow scientists to discover what life forms can exist in the most extreme conditions and thus whether life could exist on some other bodies in the solar system.

There has long been excitement among some scientists that life theoretically could exist on Saturn’s moon Enceladus and the Jupiter moon Europa as they are believed to have oceans, or large lakes, beneath their icy shells.

Valerie Massson-Delmotte of the climate and environment laboratory at the French Atomic Energy Commission, said Lake Vostok was of particular interest as it had been formed over the course of 400,000 years.

“There is also a strong interest from biologists to study the forms of life that could exist in these extreme conditions which have been separated from the rest of the world environment for several million years,” she said.

The possibility that the lake existed had first been suggested by a Soviet scientist in 1957. Scientific research drilling in the area started in 1989 and the lake’s existence was confirmed only in 1996.

But efforts to reach its surface were suspended two years later amid fears that the process could contaminate the waters.

After developing new techniques in an attempt to ease environmental concerns, attempts to drill down through the deep ice sheet to the lake’s surface resumed.

The Russian researchers intend to start drilling again and obtain water samples from the lake for analysis in December after a ten-month break due to harsh weather conditions.

The hidden lakes of the Antarctic are seen as one of the final frontiers in exploring the Earth and several teams from other nations are also engaged in similar projects.
