A big Iceberg broke off the Petermann Glacier says NASA

Each zone in Greenland comes to a name very well identified. The Petermann glacier, slides into the sea along the northwestern coast of Greenland, which ends in a giant floating ice tongue. Like other glaciers that end in the ocean, Petermann regularly has small icebergs or ice islands. An iceberg, or the island of ice broke off the Petermann Glacier in 2010. 

Almost two years later, another piece of ice has been released. An enormous iceberg in Greenland shows, another in this occasion. At NASA through Resolution Imaging Spectrometer Moderate (MODIS) aboard the Aqua satellite observed the new iceberg to drift downstream of where they broke the 16th and until July 17, 2012. 

Because Aqua is a polar orbiting satellite, which makes multiple passes over the polar regions every day. At 10:25 Coordinated Universal Time (UTC) on July 16, the iceberg was still near the glacier. At 12:00 UTC the same day (center), Berg had begun to move northward up the fjord. Timing of ice off the island with an area twice the size of Manhattan  A day later, at 09:30 UTC on July 17, Aqua spied a larger opening between the glacier and the iceberg. 


The iceberg seems to have made a slight turn to the left. "The floating extension is collapsing," said Eric Rignot of the Jet Propulsion Laboratory of NASA and the University of California-Irvine. "It's not a collapse, but it is certainly a significant event." Konrad Steffen, director of the Swiss Federal Institute for Forest, Snow and Landscape Research WSL, estimated that the iceberg was about half the size of the ice island that came out of Petermann in 2010.
