Scientists discover a huge reservoir of fresh water Under Greenland Ice Sheet

Scientists, despite sub-zero temperatures all year round, will remain liquid under the Greenland ice sheet have discovered a huge reservoir of fresh water. Effects of global warming, they may serve as a lead indicator, because they say it is important discoveries. The study is published online in the journal Nature Geoscience.

The huge aquifer in southeast Greenland , half the size of New York City covers an area of 27,000 square kilometers - State and located on the land is not very different from an underground aquifer , the researchers say . Crew , indicating that water remains liquid during the cold winter before the start of the summer melt season has discovered reservoir .

Utah and Columbus, Ohio State University, Byrd Polar Research Center at the University of scientists from the surface of the ice sheet , while extracting core samples , April, reservoir discovered in 2011 and was hit by a layer of snow with water . Firn snow compacted in an area known as the aqueous layer , was 33 feet below the surface .

For more evidence of liquid water beneath the surface using ground-penetrating radar to look at , the team found a continuous layer of wet stuff . At the same time , NASA's Operation Ice Bridge flew in specially equipped aircraft and ileal reservoir until far beyond the area covered by the research team found .

"This discovery was a surprise ," lead author Rick Forster, professor of geography at utah university , in a statement. According to Forster , the Greenland ice sheet contributed greatly to the current sea level rise and melting " record levels . "

" This melt water flows and sea levels will fill an important gap in the overall equation , because I mean every year the capacity of the aquifer to store water is important to understand " Forster said.

Water throughout the year, causing the liquid remains at this point , scientists are uncertain. Crew summer snow above the freezing winter temperatures in Greenland due to snow insulates it filtered down through the layers , on the melt suggests that liquid water remains .

Scientists also large aquifer do not know how it affects ice loss . I had one on ice accelerates the loss can serve as additional lubricant . On the other hand , water, sea level rise, which can slow the rate adds value .

Greenland's ice loss rate by the Intergovernmental Panel on Climate Change , which increased rapidly between 1993 and 2005 . Ice loss of about 121 billion tons per year in this period , the average per year between 2005 and 2010 and then rose to 229 billion tons . Last twenty years, the average ice loss has increased sea levels inch 00:34 .
