Drilling the ice sheet above Lake Vostok is not an easy job. Apart from having to penetrate the thick layer of ice is almost 4.000 meters, the researchers had to stay at the location listed as the coldest place in the world.
Established since 1957, Vostok Station is only 1,300 kilometers from the Earth's south pole. The sun only shines for half the year in this area, making this area becomes very cold.
On July 21, 1983, at the peak of winter, the thermometer at the station reached the lowest point -89.2 degrees Celsius. Until now, there's no other place on Earth that is colder than Vostok Station.
Living in the extremes of Russian forces peneli ¬ ti rack my brain to create shelter. An inverted T-shaped building was chosen as the best design. Researchers working in a room measuring about 10 meters long and 3 meters wide, sharing the place with jackhammers and power plants. The entire room coated heat retaining panel.
All the sacrifices made by investigators to enter the drill bit as far as possible into the layer of solid ice. To do so, the researchers created two types of drilling tools, each of which utilize the heat and electromechanical.
Thermal drill consists of a heated drill bit. Hot iron tip is in charge of making a tubular sleeve. The tube is left in the middle then be appointed to serve the ice samples.
The resulting heat melted the ice drill. A pipe installed to suck the ice water to be discharged to the surface. Used a thermal drill to a depth of 2,755 meters.
Electro-thermal drilling work to make the hole deeper. This equipment consists of a rotation of the drill is driven by an electric motor.
Behind the drill bit and the suckers are collecting samples of water that can be lifted to the surface. Drill tube itself has a metal rod gripping the wall of the borehole so that the equipment does not come with the drill bit rotates.
Electro-thermal drill was the first man-made equipment that could reach Lake Vostok on Sunday, February 5, 2012. This achievement has been warmly welcomed by researchers. "My heart is filled with joy," said Head of Arctic and Antarctic Research Institute (AAR) of Russia, Valery Lukin, after hearing reports that the Russian-made drill bit reached a depth of 3,769.3 meters. *** [ANTON WILLIAM | RIANOVOSTI | KORAN TEMPO 3794]
