Just Add Water: How scientists ...
800 kilometers to the North Pole. When the ship came about polar bears, scientists soft serve ice cream machine rental stopped and began to drill a hole in the Arctic ice to try to figure out why he was so quickly disappears. Individual soft serve ice cream machine rental floes, each the size of half a football field, drifted between narrow strips of clean water very close to the sun rising over the Arctic. According to ice pilot Arne Sorensen, soft serve ice cream machine rental Greenpeace icebreaker obviously moved farther north all the ships in the world. Nearby, in a monochrome landscape between the Norwegian archipelago of Svalbard and the North Pole, a large bear paw touching and licking of the laser scanner soft serve ice cream machine rental in the form of a lollipop as he drove past, no matter doing your job. After a moment, under the feet of scientists cracks several meters soft serve ice cream machine rental wide, forcing them to retreat hastily.

The less ice, the less sunlight reflected back into space, soft serve ice cream machine rental warming the atmosphere and causing even greater melting ice masses. Experts say that the thinning of ice in recent decades can bring an ice-free summer by 2020. And while difficult to measure soft serve ice cream machine rental thickness soft serve ice cream machine rental by satellites than the area, this information is extremely important. Revised figures managed to get by using observations from new satellite, aircraft and submarine, as well as low-tech effects on the ice itself - drilling holes and measuring the thickness of the tape measure. "Radar satellite sees only part of the ice box over the water, and since about nine tenths of ice under water, satellite gives extremely inaccurate data," - explains doctoral student at Cambridge University Till Wagner. "We are here in order to define more precisely what is in fact its thickness," - he says, standing on the ice floe on the background of the rising sun. Sea ice retreats each summer and this year ends, leaving a record low in 2007. Though there is still a week of melting ice area is less than two-thirds of what it was in the early 70s of the last century. Unlike soft serve ice cream machine rental the ice caps of Greenland to the mountains hundreds of meters thick, floating sea ice in the Arctic Ocean, and on it depends the survival of wild animals, including polar bears and walruses. Additional risks associated with the ice-free ocean surface weather violations include, as the temperature difference between the equator and the poles is a factor that contributes to global weather. If the Arctic Ocean was open in the autumn, without an insulating layer of ice, it would cause more warming polar air. As a result, one study estimated that in 2010 the total volume of Arctic sea ice has decreased by a record number, and presumably continued refinement, despite relatively stable ice extent during the last three or four years. Other scientists are considering the thickness of the new estimates obtained with the European Space Agency satellite CryoSat, which fill the gap between the information of the last American satellite ICESat and run the following in about 2016. "Preliminary map of ice thickness, developed with the help of CryoSat, demonstrates a logical agreement with the data obtained from the plane - explains expert at University College London Seymour Lacson. - Some of these data are not available until now." The aim of the researchers on ice floe near the North Pole is a three-dimensional scanning, which can help scientists better understand the shape and strength. According to one of the researchers Villa Throssell usually should be cut or plan to explore the plot, but seeing it in 3-D and combining information from the satellite will be able to get a really detailed look at what's going on with him.
