Antarctica from a height
• Antarctica from a height of
These amazing pictures of Antarctica made by means of geodesic planes in the framework of the project of mapping and monitoring the ice sheet of Antarctica Operation IceBridge.
The project is conducted by NASA Operation IceBridge forces since 2009. Thanks to him, you can see pictures of Antarctica from the height of the geodetic aircraft DC-8.

Antarctica is in the south of the Earth, Antarctica center coincides roughly with the geographic south pole. Antarctica washed by the waters of the Atlantic, Indian and Pacific oceans, sometimes informally allocated in a separate Southern Ocean. (Photo by Mario Tama):
In addition to the cold pole in Antarctica located the lowest point relative humidity, the most powerful and long-lasting wind and solar radiation is most intense. (Photo by Mario Tama):
Antarctica - the highest continent of the Earth. The average height of the continent's surface above sea level is 2000 m, and in the center of the continent reaches 4000 meters. Most of this height is a permanent ice cover of the continent. (Photo by Mario Tama):

Most of this height is a permanent ice cover of the continent, which is hidden under the continental relief and only 0, 3% (about 40 thousand sq. Km.) Of its area free of ice - mostly in West Antarctica and Transantarctic Mountains. (Photo by Mario Tama):
The mountains rise from the coast of West Antarctica. Western portion consists of a group of mountainous islands interconnected ice. Pacific Coast Antarctic Andes located, whose height exceeds 4000 m; the highest point of the continent - 4892 m (Photo by Mario Tama):.
Antarctic ice sheet is the largest on the planet, and is superior to the closest size Greenlandic icecap on an area of approximately 10 times. In it is concentrated about 30 million cubic meters. km of ice, ie 90% of all land ice. (Photo by Mario Tama):
ice sheet in Antarctica contains about 80% of all the fresh water of the planet; if it is completely melted, sea levels will rise by about 60 meters (for comparison, if melted Greenland ice sheet, sea level would rise by only 8 meters). (Photo by Mario Tama):

The average thickness of the Antarctic ice - 2500-2800 m, reaching a maximum value in some areas of East Antarctica - 4800 m (Photo by Mario Tama):.
According to Academician Vladimir Mikhailovich Kotlyakov, ice cover of the continent formed no later than 5 million years ago, but more likely 30-35 million years ago. (Photo by Mario Tama):
the size of a huge iceberg. Local icebergs - they record size is significantly greater than the size of the icebergs of Greenland outlet glaciers; For example, in 2000 from the Ross Ice Shelf broke off the largest known at this time (2005) iceberg B-15 area of over 10 thousand sq. m. km.

Antarctica has an extremely harsh cold climate. In East Antarctica, at the Soviet Antarctic station "Vostok" July 21, 1983 registered the lowest temperature on Earth in the history of meteorological measurements: 89, 2 degrees below zero. The area is considered a pole of the Earth's cold.
December 9, 2013 at the conference of the American Geophysical Union, a group of American researchers reported that August 10, 2010 the air temperature in Antarctica is one of the points dropped to -93, 2 ° C. (Photo: NASA | Michael Studinger):
