Scientists think that they succeeded for the first time! – Obtain samples of living organisms of the sub glacial Lake in Antarctica. The findings probably will help justify the possibility of life on Jupiter and Saturn.
In late January, the American broke to Lake Alonso through the 800 m of ice. Researchers have had only two days filled with sunshine, to take samples of the water until the well will not be closed. Then another day was spent on the expansion of the hole, and then the scientists within two days took the samples. And here’s the result: bountiful samples of water and sediment, as well as hundreds of Petri dishes with living organisms, which produces for further intensive study in laboratories.
The first step is to make sure that microbes do not fall into the Lake during drilling, despite the grease out of hot water, which is specifically designed to eliminate possible contamination during drilling using kerosene.
In order to highlight the DNA of microscopic organisms in the water add commonly used dye, and green glow told that life there is. Most here probably hemolitotrofov that feed on inorganic iron, sulfur and other elements. “We can say with certainty that the Lake under the glacier flow Uillansa contains microbiological cleanness group surviving in the dark and cold conditions,” said Chief biologist John WISSARD Prisku program from the University of United States. Note that the temperature of the water in the Lake is kept on-0.5° c.
The American group is one of the three, employed an extensive system of lakes and streams, which is located beneath the ice of Antarctica. The British who were trying to reach much deeper Lake Ellsworth, in December had to return home due to equipment failure, while the work to obtain samples of water from Lake Vostok. To recap, Lake Vostok was achieved with great fanfare last year. It has a much deeper (4 km below the surface of the ice) and larger than all the other Antarctic Lakes; Besides (like Ellsworth) lies under the ice, colder than Lake Uillansa and, unlike him, is less linked to the underground river system.
Subglacial lakes and streams in Antarctica were discovered relatively recently, and the scale of the system managed to realize only in recent years. Lake Alonso, for example, was first described in 2007-by Helen Fricker of the Scripps oceanographic institution (United States). Using satellite data, scientists discovered the periodic raising and lowering the surface ice flow Alonso in 2003-2006, that made a presumption under a glacier lake.
Indirectly opening contributed to global warming, which triggered a closer monitoring of the dynamics of the ice, after all, about 90% of the Earth’s fresh water is locked in glaciers. While penetrating subglacial lakes do not affect climate change directly, their interaction with the icy environment plays an important role in the behavior of ice sheets. The program therefore WISSARD aimed not only obtaining specimens of exotic life forms, but also study the periodic inflow and outflow of water in and out of Lake Uillansa at a speed of movement upstream glacial flow to the ocean.
