 Glacier Blamed For Berg That Sank Titanic Unleashes More Ice

 The glacier that's blamed for producing the iceberg that sunk the Titanic has been pushing much more ice into the ocean over the past two years, according to a new study published Monday. 
 
 Greenland's Jakobshavn glacier is essentially a river of ice that floats in a narrow valley. Over the past decade, it has been flowing faster toward the sea. And that rate has increased rapidly over the past two summers, apparently because the front of the glacier is now sitting in deep water, so there's not much holding it back. 
 
 As the glacier crumbles into the sea, the ice has been surging forward at the rate of 150 feet per day, according to a study published in the journal The Cryosphere. 
 
 That makes Jakobshavn by far the fastest-moving major glacier in the world, according to Ian Joughin at the University of Washington. Other Greenland glaciers have also started to flow a bit faster in recent years. 
 
 "As the glaciers flow faster, they discharge more icebergs to the ocean, and as you pour more ice into the ocean, sea level goes up and the ice sheet goes down," Joughin says. "So the fact that this glacier is flowing so much faster means it's actually making a much bigger contribution to sea level." 
 
 Over the past decade, the Jakobshavn glacier has added enough water to raise sea level by a millimeter — about the thickness of a dime. 
 
 Add up all the other Greenland glaciers, and the melt rate is currently about 3 inches a century. But Joughin says that rate is increasing as the sea and the air around Greenland warm up. ||||| Jakobshavn Glacier has bagged the tile of Greenland's Fastest Glacier in Greenland: In the summer of 2012 it reached a record speed of over 150 feet per day.

 The glacier that produced the iceberg that sank the Titanic in 1912 is on the move – this time at a record-breaking speed. 
 
 Jakobshavn Glacier (also known as Jakobshavn Isbræ) is now moving at a speed that appears to be the fastest ever recorded for any Greenlandic glacier, according to researchers from the University of Washington and Germany's space agency, who measured the speed of the glacier in 2012 and 2013 using satellite data. The results were published in a paper titled, "Further summer speedup of Jakobshavn Isbræ," on Feb. 3 in The Cryosphere, an open access journal of the European Geosciences Union. 
 
 "We are now seeing summer speeds more than four times what they were in the 1990s, on a glacier which at that time was believed to be one of the fastest, if not the fastest, glacier in Greenland," said Ian Joughin, a glaciologist at the University of Washington's Polar Science Center and the lead author of the paper. Due to all the ice that falls on Greenland every year, an ice sheet is created. 
 
 "It is like honey spreading out," he says. 
 
 Jakobshavn Glacier is actually a fast current of ice within this ice sheet. When the current reaches the ocean, chunks of ice breakaway from the glacier. Eventually these icebergs melt causing a sea levels to rise, Dr. Joughin told the Monitor. 
 
 In the summer of 2012 Jakobshavn Glacier was moving at an alarming pace and reached a record speed of more than 17 kilometers per year, or over 46 metres per day, according to a press release from the European Geosciences Union. 
 
 What is remarkable about the Jakobshavn Glacier is that "even after all the mass that it has already lost, it is able to keep doing it, year after year,” said Benjamin Smith, a glaciologist at the UW’s Polar Science Center and co-author of the paper. “A smaller glacier would settle down after losing that much mass. Jakobshavn’s ability to drain ice from the ice sheet is really exceptional among all of the glaciers in Greenland.” 
 
 As the Arctic region warms, Greenland glaciers such as Jakobshavn have been thinning and 'calving' – or breaking off – icebergs further and further inland. This means that, even though the glacier is flowing towards the coast and carrying more ice into the ocean, its calving front is actually retreating, stated the press release. 
 
 The scientists note that the glacial motion during summer is not permanent, as glaciers tend to move more slowly over the winter. 
 
 But in a press release from the University of Washington, researchers say that Jakobshavn Glacier's average annual speed over the past few years is nearly three times what it was in the 1990s. 
 
 “We know that from 2000 to 2010 this glacier alone increased sea level by about 4/100 of an inch (1 mm). With the additional speed it likely will contribute a bit more than this over the next decade,” Joughin said. 
 
 It appears that increase in Greenland's temperature could be the reason, he says. 
 
 The effort is to understand what will happen 20 years down the line, he adds.
– The glacier that spawned the iceberg that sank the Titanic isn't deliberately trying to send thousands more people to watery graves—but it couldn't be doing much better if it was. Researchers say that as the Arctic warms, Greenland's Jakobshavn glacier has become the fastest-moving glacier in the world, hitting speeds of 150 feet per day in summer 2012 and pushing more and more ice into the sea, the Christian Science Monitor reports. The glacier—essentially a river of ice inside the Greenland ice sheet—is moving around four times as fast as it was in the '90s, when it was already one of the world's fastest-moving glaciers. This glacier alone has contributed an extra millimeter to sea levels over the last decade, making the acceleration alarming news. "As the glaciers flow faster, they discharge more icebergs to the ocean, and as you pour more ice into the ocean, sea level goes up and the ice sheet goes down," the lead researcher tells NPR. "So the fact that this glacier is flowing so much faster means it's actually making a much bigger contribution to sea level." Scientists tracking the melting ice have employed an unusual tool—rubber ducks.
