If the ice shroud on Greenland ever melt , this is what you ’ll see . It ’s an tremendous canyon press clipping through the substance of the island , the size of the Grand Canyon . scientist recently find out it with meth - penetrating radar .
Over at Discover cartridge holder , Becky Lang writes :
The canyon is up to 2,600 foot ( 800 meters ) deep , and its scale in width and distance rivals parts of the Grand Canyon in Arizona . It lead off beneath the ice in fundamental Greenland and thread its way north to drain into the Arctic Ocean , according to new research from scientists at the University of Bristol , as well as researcher from Canada and Italy . The determination helps explain why Greenland does n’t have pools of water under its ice sheet like Antarctica does : The canon may be helping divert meltwater and thus keeping Greenland ’s ice sheet static .
trillion of years ago , when Greenland was n’t crush under its massive frosting sheet , this canyon might have been a profuse region full of river , plants and beast . But then climate fluctuations lowered temperatures , destroy all life in this once - fecund area .
The find of this mega - canyon was announced today in Science . Read thefull scientific subject in Science magazine .
