Wind farms in the lives of 18.04.2012

Despite the brisk pace of the freezing Arctic sea ice area of the October remained relatively low. This October, refrigerated trailers the average jääalaksi measured 7.10 million square miles is a measurement of the history of the second smallest Arctic sea ice in the October area. It is about 24 percent refrigerated trailers lower than its 1979-2000 average October.
Large stretches of open water was now the end of October Beaufort refrigerated trailers Sea and the Chukchi Sea yet. Thanks to the open water of air remained unusually warm in the seas, and the Siberian coast. In mid-October temperatures were up to 5-8 degrees higher than average.
Higher up in the atmosphere, a thousand meters above sea level, in October was warmer than average in most parts of the Arctic Ocean. On average temperatures viipyilivät there 1-4 C above average, which is also unusual.
The northern polar region of low-28.10.2011 1 kilometer of altitude. The colors from green to yellow to red reflecting higher average temperatures. Colder than average (blue and purple refrigerated trailers shades) was mainly in Greenland and northeastern Canada. Finland is the top left of the map, at about eleven.

Development of ice conditions may result in the traditional way the U.S. NSIDC's on the map, which is updated refrigerated trailers once a day. Sea ice, when it is, you may now also staring refrigerated trailers at the camera via the web, when it works. This camera is located in Barrow Alaska, that is, in practice, Beaufort and Chukchi Sea border.
Another current webcam can be found in the Canadian Churchill, where the polar bears of Hudson Bay waiting for norkoilee freezing - in other words, waiting for access to the hyljeapajille. The picture can be seen with any luck, perhaps mound lounging polar bear or polar bear maastokuormurillisen säpiseviä tourists.
Sea ice decline in the long term can really be hard pressed to drive the polar bear (see Weather Station 16.2.). As a small development, an improved now becomes that of a polar bear endangerment classification has been revised in Canada. The new estimates that the polar bear as a species need special supervision. In practice, this means that the Canadian authorities to draw up a national plan on how to prevent the endangerment of polar bear serious.
NASA's IceBridge scientists are once again on the ground to measure the ice at, this time in Antarctica. On the 14 th day study on a flight, they found quite by chance a long crack in Pine Island shelfijäätikössä. Specifically for this detailed examination of the surprise discovery was made yet another flight.
The crack was when found about 29 miles long and an average of 80 meters wide and 50-60 meters deep. It will grow, as a result, the glacier is cleaved off in time about 880 square kilometers refrigerated trailers in size raft-like an iceberg. Cleavage is thought to take place perhaps as early as end of this year or early next year. The last time the Pine Island glacier, or PIG (in english Pine Island Glacier) spawned a giant iceberg in 2007.
On the other hand, it is known that the PIG has lost mass rapidly refrigerated trailers since 2006. It is the largest single conduit through which the West Antarctic ice flows into the sea. And the times of this iceberg is loose and drifted off, the outer edge of the Pig is probably retreated further than at any time since 1940, after, or during the time when the edge of the glacier position has been followed.
While this detachment of the tip of the iceberg, it is relatively usual thing, the researchers are excited about the fact that happened on the spot at the right time. Giant iceberg birth process has not been measured from the plane such detail. Previous research similar events has been based on satellite images. Photographs, we can try to discern what kind of spectacle it is to question
Many short crack and a longer one that will continue far out of the picture. Pine Island shelfijäätikkö, Antarctica, October 2011. See more pictures of the crack. (Photo: NASA / GSFC / Michael refrigerated trailers Studinger / Creative Commons)
