The Greenland glaciers are melting faster than was considered earlier




Flowing into the ocean, the glaciers of Greenland are at a greater depth than previously thought, allowing the ocean waters to wash away their much. This process can increase the sea level on the planet is much faster than previous estimates. Such results are received, a team of researchers led by Eric Ringo from UCLA and the jet propulsion Laboratory of NASA.

Researchers for three years fought the turbulent waters near Greenland to be the world's first underwater map of the glaciers. The results of the study were published in leading scientific journals, including Geophysical Research Letters and is available online.

"It was very difficult to carry out measurements at depths of several hundred meters in ice-infested fjords," wrote Ringo. Ringo, and his colleagues, Ian Fenty from JPL, Chillan Tea and young KSU from UCI and Chris Pace from Terrasond Ltd. received and analyzed values of depth, salinity and temperature in the deep waters and investigated their impact on the edge of the Greenland ice sheet.






Scientists found that some glaciers are giant earthen sills to protect them from exposure to salt water while others are placed directly on the seabed and heavily eroded by salt water, and this means that they can collapse and melt away much earlier.

"Early forecasts did not take this fact into account and, consequently, underestimated how quickly the glaciers will respond to climate change," said Ringo published
