USA, 05/08/2016 (The People’s Daily Online) – NASA researchers have developed the first map on the state of the lower layer of the frozen surface of Greenland, which shows that most of the areas where data are thawed, while the interior of the island remains ice cream, according to El Mundo
this mapping thaw the frozen base Greenland, published in the journal of Geophysical Research -. Earth Surface, it is important to better predict how evolving this area earth in case the weather is warmer, according to the Center Goddard Space Flight NASA.
the thick Greenland ice sheet insulates the rocky soil of the cold surface temperatures, so the bottom of the ice can be even tens of hotter than the top heat that comes from the depths of earth degrees.
whether the soil bed Greenland is wet, slippery or dry is essential to predict how the ice will flow in the future, but scientists have very few direct observations of the thermal conditions below the ice sheet, which is obtained through less than two dozen wells.
