It is located near the Greenlandic town of Ilulissat (colonial name in Danish: Jakobshavn) and ends at the sea in the Ilulissat Icefjord. … Acquired July 22, 2010, this high-resolution image shows cracks on the surface of the Petermann Glacier in northwestern Greenland. Mit Fließgeschwindigkeiten von 7000 Metern pro Jahr gilt (Stand 2008) der Gletscher als der dauerhaft am schnellsten fließende Der Jakobshavn Isbræ ist einer von mehreren grönländischen Meeresgletschern, an denen Geological Survey of Denmark and Greenland (GEUS): I. Joughin, B. E. Smith, D. E. Shean, D. Floricioiu: Süddeutsche Zeitung Nr. Movement reached more than 17,000 metres per year.
According to University of Washington glaciologist Ian Joughin, the end of every summer for the last several years has seen Jakobshavn’s calving front move about 600 meters (2,000 feet) farther inland than the summer before.Jakobshavn’s ongoing retreat coincides with faster rates of flow. 292, 18. Scientists' interest in the glacier lies in its role as a drainage outlet for the Greenland Ice Sheet. Some features of this site are not compatible with your browser. Greenland's Jakobshavn Glacier Reacts to Changing Ocean Temperatures - Duration: 3:11. It's famous among glaciers as the source of the iceberg that sunk the Titanic—but it's responsible for more icebergs than that. More than likely, it was Jakobshavn that spawned the iceberg that sank the Titanic. “These images are a very good example of the changes taking place in Greenland.”“What is important is that the ice front, or calving front, keeps retreating inland at galloping speeds,” Rignot said. More than likely, it was Jakobshavn that spawned the iceberg that sank the Titanic.
Die Linien markieren den fortschreitenden Rückzug der Kalbungsfront des westgrönländischen Gletschers von 1851 bis 2006. On average, the glacier moved nearly three times faster in 2012 than it did in the mid-1990s.Scientists track the calving rate and speed of Jakobshavn in part because the glacier is responsible for draining a large portion of the Greenland Ice Sheet.
The recently abandoned settlement of Jakobshavn is one of the fastest moving glaciers, flowing at its terminus at speeds that used to be around 20 metres (66 ft) per dayThe second mechanism is a "Jakobshavn effect", coined by Terry Hughes,This mechanism is supported by the data indicating no significant seasonal velocity changes at the calving front and the acceleration propagating upglacier from the calving front.In 2012 a significant acceleration of Jakobshavn was observed, with summer speeds up to 4 times its speed in the 1990s, and average annual speeds of 3 times its 1990s speed.
Jakobshavn—Greenland’s fastest-moving glacier—is notorious for such losses; in 2014 the glacier These images were acquired 16 days apart in August 2015 by the “The calving events of Jakobshavn are becoming more spectacular with time, and I am in awe with the calving speed and retreat rate of this glacier,” said Eric Rignot, a glaciologist at the Jet Propulsion Laboratory. Jakobshavn—Greenland’s fastest-moving glacier—is notorious for such losses; in 2014 the glacier shed kilometers of ice from its front. Acquired in 2001 and 2010, these natural-color images show substantial retreat in the Jakobshavn Glacier. Evidence also exists for a deep subglacial trench beneath the glacial outlet, identified through Airborne altimetry and satellite imagery show that Greenland's largest glacier, the Jakobshavn, has been re-advancing, slowing and thickening by over 100 feet from 2016 to 2018.New NASA data show that the Jakobshavn Glacier also grew from 2018 into 2019, marking three consecutive years of growth.

A recent study team from NASA's Jet Propulsion Laboratory in Pasadena, California, determined that water transported to the area around the glacier by a key ocean current has been colder than it was prior to 2016, when the growth began. Summer is the season to watch for ice loss from the outlet glaciers lining the perimeter of Greenland. 3:11. : Sermeq Kujalleq, „Südlicher Gletscher“) ist ein nahe dem grönländischen Ilulissat (dänisch Jakobshavn) gelegener Auslassgletscher.Der Gletscher stellt einen beträchtlichen Teil der grönländischen Eismasse dar. In 2015, the glacier lost yet another large chunk of ice. Jakobshavn has been a name used for this glacier in scientific literature since 1853 when Danish geologist There is evidence that people have inhabited the area around the glacier for up to 4000 years. The recently abandoned settlement of Jakobshavn is one of the fastest moving glaciers, flowing at its terminus at speeds that used to be around 20 metres (66 ft) per dayThe second mechanism is a "Jakobshavn effect", coined by Terry Hughes,This mechanism is supported by the data indicating no significant seasonal velocity changes at the calving front and the acceleration propagating upglacier from the calving front.In 2012 a significant acceleration of Jakobshavn was observed, with summer speeds up to 4 times its speed in the 1990s, and average annual speeds of 3 times its 1990s speed. In the summer of 2012, Jakobshavn accelerated to speeds not seen before, surging at a rate of 17 kilometers (10 miles) per year. Jakobshavn has been a name used for this glacier in scientific literature since 1853 when Danish geologist There is evidence that people have inhabited the area around the glacier for up to 4000 years. Natural processes and human-caused warming have combined to bring rapid change to a glacier in southeastern Alaska.
Jakobshavn's growth did not come as a surprise to scientists.
