The study of ancient lake in Antarctica may explain the future of Earth Scientists have shown
British scientists are hoping that the ancient lake Ellsworth, located at a depth of 3 kilometers under the cover of ice, will help in the study of climate change, sea level change and the emergence of new forms of life.
Ice cover over the lake does not produce geothermal heat of the earth, protecting the lake from freezing. In October, a team of scientists travel to Antarctica for the first phase of the study, which will cost at least £ 7 million. In order to obtain samples of water and sediments in November to occur drilling operation.
For many years, scientists believed that new and unique forms of life to develop in the dark under sterile conditions of complete isolation at a temperature of minus 25 degrees Celsius. Scientists want to find archaea and eukaryotes, which could help to understand how life originated and evolved on Earth.
"The discovery of life forms in the lake, isolated from the rest of the biosphere for supposedly half a million years, can tell the origin of life and the limitations of her world, and will help to understand the evolution of life in extraterrestrial environments. If scientists do not find, will provide data on the conditions under which life on Earth could not exist, "- said the coordinator of the study, David Pierce.
Some scientists, however, are concerned that the penetration in the pristine environment can lead to irreversible consequences. To avoid contamination of the lake, scientists will use sterile technology.
Russian scientists were forced to postpone the drilling operation on the East Lake Vostok. Britons hoping to be first in taking samples and study samples obtained from the depths of the lake in Antarctica.
