SCIENTISTS STILL want to be sure. Do not advertise SUCCESS
After many years of research, most likely Russian scientists arrived at last to a hidden four kilometers beneath the ice of Lake Vostok. Russians think that is a great opportunity for science - trapped under ice in Antarctica for nearly 20 million years ago a giant lake may contain previously unknown life forms. Scientists are detailed calculations and studies toconfirm that dowiercili to the desired goal.
- Our scientists have stopped drilling at a depth of 3768 meters to reach the surface of the lake podlodowcowego - informed source, quoted on Monday by the agency RIA Novosti.The Agency has not provided as to why a few days earlier you could not make contact with scientists.
Calmly and confidently
The enthusiasm associated with this information, however, dampens Valery Lukin, head of the Russian Antarctic expedition. In Tuesday's speech to the service nature.com reservedon the data from sensors that monitor drilling are not yet fully analyzed. This is most likely tooccur Wednesday. - Only in the hand of the results I will be able to announce that we got toLake Vostok - he said.
Requires at least verify the exact information on the exact thickness of the drilled ice andliquid level in the well. Then the scientists will be able to confirm that to be drilled into the lake. - When we gain official confirmation, will forward the information immediately to the international community - has provided "Nature" Lukin.
Most of the team involved in the drilling had already left the station Vostok and flew aboardthe Russian icebreaker Akademik Fedorov. The site has two crew members, who watch over the well. In the Antarctic winter season is approaching.
Lake - giant
Hidden Lake Vostok is 3750 feet below the surface of the ice sheet of Antarctica. It is the largest and deepest lake located hidden under the ice of Antarctica, has about 15 690 kmsquare. Based on the analysis of samples of ice drilled just above the water, scientists estimated that the last time, light and air from the surface of the lake could reach about 15-20 million years ago.
Russian scientists hope that in the lake Vostok, the largest of the network hidden underAntarctic glacier, and one of the largest in the world, they can maintain a previously unknown life forms. Examination of the lake is also help in gaining knowledge of how life evolved before the Ice Age.
Due to geothermal heat sources, the water in the lake is about - 3 ° C. Do not freezebecause it is under pressure, caused by millions of tons of ice that cover the them. In addition, the water is to be highly saturated with oxygen, about 50 times more than normalon the surface of lakes.
Scientists from the U.S. and Great Britain followed in the footsteps of fellow Russian andrun their own fact-finding missions to find other hidden under the ice of lakes.
