the Lake Vostok magnetic anomaly

Antarctica is the continent's most remote, whose access and climate are respectively the most difficult and the most extreme (up to -89.2 degrees Celsius!). During 6 months of the year remains in complete darkness, while in the austral summer, a pale sun shines near the horizon. Without sea ice, the Antarctic lands have a total of approximately 14 million square kilometers. Therefore, this is the fifth continent in the world.
Although since antiquity had speculated about its existence, representing it in various maps of the Middle Ages with the name of Terra Australis Incognita, the continent was first sighted only 27 January 1820 by the Imperial Navy officer Fabian Gottlieb von Bellingshausen Russian, while the first man to walk on their land was the Anglo-American John Davis, on February 7, 1821.
In 1908, Britain claimed sovereignty over the portion of Antarctica that extends from the South Pole and the sixtieth parallel of longitude 20 west to the meridian 80 West. Subsequently, seven other nations sovereign (New Zealand, France, Australia, Nazi Germany, Norway, Chile, Argentina), presented official requests to international organizations for control over as many areas of Antarctica (Nazi Germany's claim on the land known as New Swabia lost everything in value over the outcome of the Second World War).
Strangely, the Soviet Union (and later the Russian Federation) and the United States of America, although it was a Russian and an Anglo-American, respectively, the first to sight Antarctica and the first to step on it, have not so far presented formal complaints about areas of Antarctica, but that have merely stated that they reserve the right to make in the future.
However, the Antarctic territorial claims have not been made on the continent. Marie Byrd Land (about 1.6 million square kilometers), explored by the American Richard Byrd in 1929, was never requested by any sovereign state. Why?
The crucial date for the exploration of Antarctica was the month of December 1911, when the Norwegian Roald Amundsen reached the South Pole in a daring expedition. The scouts usually always have been sent by the secret services states and often have the task of identifying areas suitable for mining and also those that are militarily strategic. After the end of World War II, some sovereign nations established some bases in Antarctica, officially for scientific reasons.
The Soviet Union built a base in the coordinates 78 degrees 27 'South and 106 degrees 50' East, and called Vostok (East, in Russian). Today, Vostok Station, located at 3488 meters above sea level (just over a crust of ice over 3600 feet thick), is the most isolated of the 67 scientific stations (belonging to 30 states), which currently exist in Antarctica, and their base is the Mirny station in the Antarctic coast.

The left image shows the ice surface above Lake Vostok. On the right, you can "see" the lake through the ice. The image also shows the rocks out of the lake (in brown) and the lake's surface below 4 km of ice (in blue).
In 1970, after radar surveys carried out by aircraft, the Russians said their base had been built by chance just at the spot where the lowest 3623 meters, was the largest subglacial lake in the world which was also named Vostok. should be remembered that subglacial lakes in Antarctica are about 140, but Vostok is certainly the largest and the most mysterious. Lake Vostok, which contains liquid water, is 250 kilometers long and 60 wide. The total volume of water it contains is about 5400 kilometers cubes (would be sufficient for water consumption of about 50 million people for 3 years, calculating one hundred liters per person per day!). ![]() A group of Russian scientists are just a few meters to get to Lake Vostok. Among the many mysteries that lies Lake Vostok, this includes the altitude above sea level of the bottom of the lake: if we consider data on Antarctic Research Scientific Commitee the surface of the lake is located 3623 meters below Vostok Station, which itself is 3488 meters above the sea level. The surface of the lake would be, therefore, to 135 meters below sea level, and as the maximum depth is 800 meters (depth average of 670 meters), the lake bottom would be found to 935 meters below the sea. In 1998, some Russian scientists, U.S. and French drilled in the bark to reach about 120 meters before the lake surface, with the official excuse to avoid contamination. There have been further drilling (2008 and 2009), but none, until today, has delved into the crust of ice to the point of the lake. The analysis of ice extracted identified traces of methane, bacteria, pollen remains of multicellular marine and other multicellular creatures unknown residues. Of studies is concluded that Lake Vostok is a super-saturated oxygen atmosphere (the concentration of this could be 50 times higher that of a normal lake surface). ![]() ![]() seismic recordings occurred in the vicinity of Lake Vostok. © by M.

Electromagnetic energy reflected on the lake (blue curve) is much greater than on the rock (red curve). The white line is the famous Vostok ice core.

American psychic Edgar Cayce, the Atlanteans hid in a huge glass lost continent would be their source of energy for a long time. Some researchers who support the theory of antediluvian civilizations, the Lake Vostok magnetic anomaly would be just the crystal described by Cayce. Lake Vostok may be the best known and largest subglacial lake in the world but not alone. Two of its larger neighbors are located as 90 º E and Sovetskaya. Coincidentally the Russian research station was built above it. © by M. Studinger, 2006. ![]() ![]() In my opinion, although the maps of the Middle Ages does not prove anything definitive (the coast, "Antarctic" Piri Reis map could be the Patagonia and southern landmass on a map of Phineas could Oronzo be the result of the alleged union of Terra Australis Incognita to the northern coasts of Australia, perhaps sighted by Portuguese navigators in the second decade of the sixteenth century), and Roberto Rengifo strange theory has no basis, it is only on weak assumptions, we can not rule out that Antarctica has enjoyed a different climate of the current, much warmer, around ten thousand years before Christ. Theory also could confirm Mendes Correa. For now you can not say with certainty whether the Lake Vostok magnetic anomaly has a natural or artificial. It is right to proceed in small steps, provided with the scientific method, but, considering that science can not answer all the questions, I think it is wise not to rule out certain hypotheses, "strange" by some mystics and psychics, who could, with their perceptions, indicate to scientists track to reach the solution of the mystery. By Yuri Leveratto ![]() A group of Russian scientists are just a few meters to get to Lake Vostok. Water testing to be obtained will be sent to the laboratory of the Institute of Arctic and Antarctic Research in St. Petersburg for analysis. These tests are crucial to the investigation of the possibility of finding life on Europa, Jupiter's moon, in a recent study has estimated that Europe has sufficient amount of liquid water and it has a high oxygen concentration, even greater than our seas. Similar concentrations would be sufficient to maintain not only microorganisms, but life forms alien complex. is not unreasonable to suggest that hardy creatures could thrive in the waters of Lake Vostok, due to high levels of natural antioxidants over millions of years of evolutionary isolation, and in an extreme environment, may have created some truly agencies strange and tolerant. This idea is supported by samples taken from the ice just above Lake Vostok, where some fossils have been found microbial and unidentified. - Scientist says Europe, Jupiter's moon, is appropriate for life - some moons of Jupiter and Saturn meet conditions for life ![]() - Openings at the poles truth or fiction?
