The Greenland ice sheet is massive, mysterious -- and melting. Using advanced technology, scientists are revealing its secrets for the first time, and what they've found is amazing: hidden under the ice sheet is a vast aquifer that holds a Lake Tahoe-sized volume of water from the summer melt. Does this water stay there, or does it find its way out to the ocean and contribute to global sea level rise? Join glaciologist Kristin Poinar for a trip to this frozen, forgotten land to find out. "The aquifer water drives the crevasse all the way to the base of the ice sheet, a thousand meters below". "The Greenland ice sheet is huge, the size of Mexico. And it's ice from top to bottom is two miles thick". So...is the ice sheet thickness a thousand meters, or two miles??? BIG difference! (Unless the snow {aquifer} is over seven thousand feet.) A much simpler and more accurate method of determiming the amount of glacial loss is the hundreds of millions of years of...
