Scientists discover an ocean 400 miles beneath our feet that could fill our oceans three times over
2014-06-17 15:44:38| Extremetech
After decades of theorizing and searching, scientists are reporting that they've finally found a massive reservoir of water in the Earth's mantle -- a reservoir so vast that could fill the Earth's oceans three times over. As always, the more we understand about how the Earth formed, and how its multitude of interior layers continue to function, the more accurately we can predict the future. Weather, sea levels, climate change -- these are all closely linked to the tectonic activity that endlessly churns away beneath our feet.
Newly Discovered Frozen Underworld Beneath Greenland Speeding its Flow to the Sea
2014-06-16 20:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World: Beneath the barren whiteness of Greenland, there lies a mysterious frozen underworld, which through its melting and refreezing process, may be speeding its ice flow to the sea. Using ice-penetrating radar, researchers have discovered ragged blocks of ice as tall as city skyscrapers and as wide as the island of Manhattan at the very bottom of the ice sheet. Scientists said the findings, published in the journal Nature Geoscience, could deepen their understanding of how the ice sheets of Greenland...

Skyscraper-Size Ice Structures Discovered Beneath Greenland Ice Sheet
2014-06-16 19:43:00| Climate Ark Climate Change & Global Warming Newsfeed
EcoWatch: Beneath the barren whiteness of Greenland, a mysterious world has popped into view. Using ice-penetrating radar, researchers have discovered ragged blocks of ice as tall as city skyscrapers and as wide as the island of Manhattan at the very bottom of the ice sheet, apparently formed as water beneath the ice refreezes and warps the surrounding ice upwards. The newly revealed forms may help scientists understand more about how ice sheets behave and how they will respond to a warming climate. The...

Vast ice structures discovered beneath Greenland ice sheet
2014-06-16 16:39:00| Climate Ark Climate Change & Global Warming Newsfeed
Blue and Green: Far beneath the flat, tranquil surface of northern Greenlands ice sheet, scientists have discovered vast ice structures as tall as skyscrapers and as wide as the island of Manhattan. The formations are caused when ice at the base of the glacier melts and refreezes over hundreds of years, in a process that may be quickening the glaciers slide into the sea. Using radar from airborne surveys, researchers found that the structures, which cover about a tenth of northern Greenland, are made not...
