Seattle, Washington, USA The 2014 EGU General Assembly is taking place is Vienna, Austria from 27 April to 2 May 2014. On average, the glacier moved nearly three times faster in 2012 than it did in the mid-1990s. Jakobshavn Isbræ is Greenland's largest outlet glacier, draining about 6.5 per cent of the ice-sheet area, and it has been surveyed repeatedly since 1991 (ref. These images, produced using GLISTIN-A radar data as part of NASA's Oceans Melting Greenland (OMG) mission, show how much mass the glacier gained from 2016-17, 2017-18 and 2018-19. Meanwhile, the Jakobshavn Glacier in the south-west is moving faster than ever. What Does It Feels Like To Die? This visualization shows flow directions and relative speeds of the Jakobshavn glacier in Greenland. You'll need a small wooden block and an ice cube. EGU Media and Communications Manager Jakobshavn Isbræ (Jakobshavn Glacier) is moving ice from the Greenland ice sheet into the ocean at a speed that appears to be the fastest ever recorded. Warmer conditions can send meltwater to the glacier’s base, increasing lubrication and consequently glacier speed. All Rights Reserved. He worked for The Guardian for 32 years, becoming (among other things) letters editor, arts editor, literary editor and science editor. Cristina Surdu of the University of Waterloo in Canada and colleagues report in The Cryosphere that there has been a 22% fall in grounded ice – frozen from surface to lakebed – between 1991 and 2011. As the glacier moves we can track changes between images to produce maps of the ice flow velocity,” says Joughin. As the Arctic region warms, Greenland glaciers such as Jakobshavn Isbræ have been thinning and calving icebergs further and further inland. The EGU has a current portfolio of 15 diverse scientific journals, which use an innovative open access format, and organises a number of topical meetings, and education and outreach activities. He served on the UK committee for the International Decade for Natural Disaster Reduction. In 2012 and 2013, the front retreated more than a kilometre further inland than in previous summers, the scientists write in the new The Cryosphere study. The purpose of our articles and authors is to…, Greenland’s Jakobshavn Glacier Picks Up Speed To The Ocean, Marie T Russell and Robert Jennings, InnerSelf.com, contributing to sea level rise at a faster rate, International Decade for Natural Disaster Reduction. “We were stunned to observe such a dramatic ice decline during a period of only 20 years”. In summer, the Jakobshavn Glacier - widely thought to have spawned the iceberg that sank the Titanic - is moving about four times faster than it was in the 1990s. Header image: Iceberg from Jakobshavn Isbræ, Disko Bay. The results are published today in The Cryosphere, an open access journal of the European Geosciences Union (EGU). Find out how it beat the glacial speed record and see more beautiful photos. Melting of Greenland's glaciers contributes to sea-level rise, 2,3,4 and is expected to fuel global warming. 2). Seattle, Washington, USA This article originally appeared on Climate News Network. Calved icebergs from the nearby Twin Glaciers are seen floating on the water on 30 July, 2013 in Qaqortoq, Greenland. These new data reveal large seasonal speedups, 30 to 50% greater than previous summers. The red flow lines are from 1992 data; the blue flow lines are 2000 data. Here we present observations of surface velocity, mélange rigidity, and surface elevation to examine its behaviour over the last decade. As more ice moves from glaciers on land into the ocean, it raises sea levels. The Chain Around His Heart and The Time for Healing.

Copyright ©1985 - 2019 InnerSelf Publications. In the summer of 2012 the glacier reached a record speed of more than 17 kilometres per year, or over 46 metres per day. Currently, there’s no good way for ice scientists to measure such slow velocities in one measurement. We have extended the record of flow speed on Jakobshavn Isbræ through the summer of 2013. A fast-moving Arctic glacier which has earned a place in history is now accelerating even more quickly. This week, we focus on seeing things differently... of looking from a different perspective, with an open mind and an open heart. They note that summer speeds are temporary, with the glacier flowing more slowly over the winter months. The Jakobshavn Glacier, which is believed to have been the source of the iceberg that sank the Titanic in 1912, was recorded moving at roughly 10 miles per year – the fastest speed ever recorded. The Jakobshavn Glacier, the largest glacier in Greenland is moving ice from land into the ocean at a speed that appears to be the fastest ever recorded. But they add that even the annually averaged speedup over the past couple of years is nearly 3 times what it was in the 1990s. New NASA data shows that Jakobshavn Glacier — Greenland's fastest-moving and fastest-thinning glacier for most of the 2000s — grew from 2018 into 2019, marking three consecutive years of growth. In the summer of 2012 the glacier reached a record speed of more than 17 kilometres per year, or over 46 metres per day. Subscribed journalists and other members of the media receive EGU press releases under embargo (if applicable) 24 hours in advance of public dissemination. These speeds are recorded in the summer, when all glaciers are more likely to be a bit friskier. It is important to understand recent changes in the velocity of Greenland glaciers because the mass balance of the Greenland Ice Sheet is partly determined by the flow rates of these outlets.

Polar Science Center, Applied Physics Lab, University of Washington The researchers produced the data presented in the study under the NASA-sponsored Greenland Ice Mapping Project, and carried out the analysis of the data at the Center for Remote Sensing of Ice Sheets, sponsored by the US National Science Foundation. The new observations of slowing for Jakobshavn Glacier in NO WAY call into question rapid climate change. In summer 2012, Greenland's Jakobshavn Isbrae Glacier raced more than 150 feet (46 meters) per day, faster than any glacier on Earth. Jakobshavn is now flowing more slowly, thickening, and advancing toward the ocean instead of retreating farther inland. Just as with any rite of passage, whether graduation, marriage, birth of a child, a pivotal election, or the loss (or finding) of a…, Well, the US presidential election is now behind us and it's time to take stock. That works out at 46 metres a day. In summer 2012, Greenland's Jakobshavn Isbrae Glacier raced more than 150 feet (46 meters) per day, faster than any glacier on Earth. The ice stream's speed-up and near-doubling of ice flow from land into the ocean has increased the rate of sea level riseby abou… 15,16 The speed at which Jakobshavn Isbræ glacier is retreating doubled from 1996 to 2005. The calving front of the glacier is now located in a deeper area of the fjord, where the underlying rock bed is about 1300 metres below sea level, which the scientists say explains the record speeds it has achieved. The Jakobshavn glacier in Greenland slowed down and gained mass. NASA research shows that Jakobshavn Glacier, which has been Greenland's fastest-flowing and fastest-thinning glacier for the last 20 years, has made an unexpected about-face. dana.floricioiu@dlr.de, Bárbara Ferreira “As the glacier’s calving front retreats into deeper regions, it loses ice – the ice in front that is holding back the flow – causing it to speed up,” Joughin clarifies. It is a non-profit interdisciplinary learned association of scientists founded in 2002. 2 In just one day—between July 6 and 7, 2010—satellite images showed that Jakobshavn Isbrae lost approximately 2.7 square miles (7 square kilometers) of ice area. Abstract. The fastest ice flow in Greenland is the glacier Jakobshavn, which moves at the blazingly slow speed of about 16 kilometers in a year—about 180 centimeters per hour. Read more at Wikipedia Jakobshavn Glacier, InnerSelf.com | Mighty Natural.com | Climate Impact News.com | Wholistic Politics.com. The fastest ice flow in Greenland is the glacier Jakobshavn, which moves at the blazingly slow speed of about 16 kilometers in a year—about 180 centimeters per hour. Jakobshavn Isbræ, an outlet glacier off the west coast of Greenland, is losing mass faster than previously thought, due to increased melt water passing through it, as reported in a new paper.The glacier’s rapid trajectory of thinning may well represent the Greenland Ice Sheet (GrIS) ice loss rate in the near future, which could mean faster sea level rise than currently projected. Jakobshavn’s current speed of flow is about 15,000 meters per year. The speed of Greenland's fastest glacier, Jakobshavn Isbræ, has varied substantially since its speed-up in the late 1990s. The Jakobshavn Glacier is located in the southern half of Greenland, which is warmer than the northern part and closer to the Gulf Stream. 2). Individual glacier behavior—such as glacier speed, thickening, and retreat—responds to climate change AND to local conditions and short-term (year-to-year) variations. You'll need a small wooden block and an ice cube. He won the Association of British Science Writers award for science writer of the year four times. Both of these processes contribute about the same amount to sea-level rise from Greenland. Jakobshavn Isbræ (Jakobshavn Glacier) is moving ice from the Greenland ice sheet into the ocean at a speed that appears to be the fastest ever recorded. The team used satellite data to measure the speed of the glacier as part of US National Science Foundation (NSF) and NASA studies. Tim Radford is a freelance journalist. A fast-moving Arctic glacier which has earned a place in history is now accelerating even more quickly. Sometimes glaciers surge -- they move up to 10 times faster than their usual speed. This speedup of Jakobshavn Isbræ means that the glacier is adding more and more ice to the ocean, contributing to sea-level rise. Click here for more info and/or to order this book on Amazon. Click here for more info and/or to order this book on Amazon. INNERSELF - Watch the spectacular calving of the glacier as caught on film in the Academy Award nominated documentary Chasing Ice. What this means is the glacier is adding more ice to the ocean, which increases the sea-level. Remote Sensing Technology Institute Some features of www.egu.eu will not appear or function properly if your Jakobshavn Isbræ is Greenland's largest outlet glacier1, draining about 6.5 per cent of the ice-sheet area, and it has been surveyed repeatedly since 1991 (ref. In recent years, its flow into the sea has only increased. The ice stream's speed-up and near-doubling of ice flow from land into the ocean has increased the rate of sea level rise by about .06 millimeters (about .002 inches) per year, or roughly 4 percent of the 20th century rate of sea level increase. This visualization was created to support a talk at the Fall 2004 AGU meeting. Even during the winter months, ice on the lakes of Alaska has begun to decline. The speed at which Jakobshavn Isbrae glacier is retreating doubled from 1996 to 2005 (Rignot and Kanagaratnam, 2006;Kerr, 2006). Jakobshavn Isbrae is Greenland's largest outlet glacier, draining 6.5 percent of Greenland's ice sheet area. We relate changes in glacier speed to geometry through variations Try this simple experiment for yourself. The speed of the Jakobshavn Isbræ — the Jakobshavn Glacier — in western Greenland was measured by researchers from the University of Washington and … Jakobshavn Isbræ (Jakobshavn Glacier) is moving ice from the Greenland ice sheet into the ocean at a speed that appears to be the fastest ever recorded.

Abstract. Subscribe to our monthly newsletter and stay up to date with the latest EGU news. At its calving front, where the glacier effectively ends as it breaks off into icebergs, some of the ice melts while the rest is pushed out, floating into the ocean. Ian Joughin Seattle, Washington, USA (Kindle book). Abstract. In the case of Jakobshavn Isbræ, the thinning and retreat coincides with an increase in speed. By the end of this century, its calving front could retreat as far back as the head of the fjord through which the glacier flows, about 50 km upstream from where it is today. Why the speed-up? German Aerospace Center (DLR) This week, we reflect on the question: "where do we go from here?" support it. Scientists estimate the glacier added about 1 millimeter to global sea levels from 2000 to 2010; its faster flow into the ocean means Jakobshavn will add even more water over the current decade. "> +1-206-221-3177 Freeze dates in the region are now occurring on average six days later than in the past, and the ice is breaking up on average around 18 days earlier. Full citation: Joughin, I., Smith, B. E., Shean, D. E., and Floricioiu, D.: Brief Communication: Further summer speedup of Jakobshavn Isbræ, The Cryosphere, 8, 209-214, doi:10.5194/tc-8-209-2014, 2014. The new observations show that in summer of 2012 the glacier reached a record speed of more than 10.5 miles (17 kilometers) per year, or more than 150 feet (46 meters) per day. Jakobshavn is now flowing more slowly, thickening, and advancing toward the ocean instead of retreating farther inland. With accelerations like this, phrases like “glacial pace” may no longer serve as clichés of lethargic movement. Research from the Arctic shows Greenland’s fastest-flowing glacier has doubled its summer flow pace in a decade, and ice cover on Alaskan lakes is declining. Having a map of Jakobshavn’s bed has been a long-time goal of glaciologists. This research is presented in the brief communication ‘Further summer speedup of Jakobshavn Isbræ’ to appear in the EGU open access journal The Cryosphere on 3 February 2014. “We know that from 2000 to 2010 this glacier alone increased sea level by about 1mm”, said Ian Joughin, of the Polar Science Centre at the University of Washington, who led the research. Glacier elevation (b) and velocity (c) are presented as a function of distance inland from a reference position (marked by a star and labelled 'Zero'). What's Next For American Evangelicals After Trump Leaves Office? As you learned in the video, the speed of the Jakobshavn glacier dramatically increased from one foot per day to 113 feet per day, largely due to meltwater seeping underneath the glacier. 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. "> +1-206-616-9176 The Arctic ice sheet is thinning, and most of the planet’s glaciers are retreating as climates warm, so the Jakobshavn glacier is carrying less ice, at a faster rate, over shorter distances than ever before, and by the end of the century could have shifted 50 kilometres upstream. Jakobshavn Isbræ, a tidewater glacier that produces some of Greenland’s largest icebergs andhighestspeeds,reachedrecord-highflowratesin2012(Joughinandothers,2014).Weuseterrestrial ... term variations in speed on long-term glacier dynamics. Located on the west coast of Greenland, Jakobshavn Isbræ is one of the most rapidly shrinking glaciers in the world. "> +1-206-221-8727 But other satellite radar imagery has begun to reveal an ominous picture of change elsewhere in the Arctic, on the north slope of Alaska. Weßling, Germany Byrd Glacier is also moving faster than average, but unlike many other glaciers, has been sounded in the past. Jakobshavn is now flowing more slowly, thickening, and advancing toward the ocean instead of retreating farther inland. Key Facts. "> +49-89-2180-6703 In the last decade, it has more than doubled its speed, zipping down the slope at 12,600 meters per year, or just short of eight miles per year [source: NASA]. Greenland’s Jakobshavn Glacier Picks Up Speed … The speed of the Jakobshavn Isbræ — the Jakobshavn Glacier — in western Greenland was measured by researchers from the University of Washington and … The unprecedented speed appears to be the fastest ever recorded for any glacier or ice stream in Greenland or Antarctica, the researchers report in the journal The Cryosphere. According to research published in the European Geosciences Union journal The Cryosphere, summer flow speeds have doubled yet again since a Nasa measurement in 2003. 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. At a point a few kilometres inland from the terminus, the mean annual speed for 2012 is nearly three times as great as that in the mid-1990s, while the peak sum- My wife Marie and I are a mixed couple. Notice that the flow speed of the glacier has increased significantly from 1992 to 2000. He has lectured about science and the media in dozens of British and foreign cities. 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. Since measurements of Jakobshavn Isbrae were first taken in 1850, the glacier has gradually receded, finally coming to rest at a certain point for the past 5 decades. A new study has found that the Jakobshavn Glacier, in the south-west of Greenland, is moving more than 17 kilometres per year, or over 46 metres per day. The meeting’s sessions cover a wide range of topics, including volcanology, planetary exploration, the Earth’s internal structure and atmosphere, climate, energy, and resources. As you learned in the video, the speed of the Jakobshavn glacier dramatically increased from one foot per day to 113 feet per day, largely due to meltwater seeping underneath the glacier. Researchers from the University of Washington and the German Space Agency (DLR) measured the dramatic speeds of the fast-flowing glacier in 2012 and 2013. Try this simple experiment for yourself. Here's why that is good and bad. However, from 1997 to 2003, the glacier has begun to recede again, this time almost doubling in speed. The ice stream's speed-up and near-doubling of ice flow from land into the ocean has increased the rate of sea level rise by about .06 millimeters (about .002 inches) per year, or roughly 4 percent of the 20th century rate of sea level increase. media@egu.eu. Jakobshavn is one of the fastest moving glaciers, flowing at its terminus at speeds that used to be around 20 metres (66 ft) per day but are over 45 metres (150 ft) per day when averaged annually, with summer speeds even higher (as measured 2012-2013). You need to be fairly fit to withstand the journey there, which Id say was a tad more than bumpy!. These flow rates are unprecedented: they appear to be the fastest ever recorded for any glacier or ice stream in Greenland or Antarctica, the researchers say. Jakobshavn Glacier. Many glaciers in Greenland and in the Antarctic Peninsula are accelerating, which is generally attributed to warmer conditions and more meltwater lubricating the bed of the glacier. dshean@uw.edu, Dana Floricioiu Principal Engineer and Affiliate Professor, Earth and Space Sciences But right now it is also contributing to sea level rise at a faster rate. Department of Earth and Space Sciences, University of Washington PhD Student That was because they already had temperature and precipitation records from Barrow dating back five decades. On average, the glacier moved nearly three times faster in 2012 than it did in the mid-1990s. The finding is important for many reasons. By 2003, this glacier—already among the world's fastest-moving—reached speeds of more than 7.8 miles (12.6 kilometers) per year. Science that Changed the World: The untold story of the other 1960s revolutionby Tim Radford. But even when averaged over the whole year, the glacier’s flow has accelerated threefold since the 1990s. Since measurements of Jakobshavn Isbrae were first taken in 1850, the glacier has gradually receded, finally coming to rest at a certain point for the past 5 decades. Geosciences Instrumentation and Data Systems, Geochemistry, Mineralogy, Petrology & Volcanology, Stratigraphy, Sedimentology and Palaeontology, Greenland’s fastest glacier reaches record speeds, http://www.the-cryosphere.net/8/209/2014/tc-8-209-2014.html, Brief Communication: Further summer speedup of Jakobshavn Isbræ, Read this press release in simplified language, Iceberg in front of Jakobshavn Isbræ calving front, Tabular iceberg in front of the Jakobshavn Isbræ terminus.

The Jakobshavn Glacier in Greenland spent many years moving between 5,700 and 6,700 meters per year. While winterflowspeedhasnotincreased substantially overthelast threewinters, thereremains a strong seasonal variation in flow speed that coincides with a cycle of summer thinning and winter thickening. That's 11 miles (17 kilometers) per year. Its annual General Assembly is the largest and most prominent European geosciences event, attracting over 11,000 scientists from all over the world.

The Jakobshavn Isbrae (the Danish word for glacier) is a massive river of ice from the Greenland ice sheet to an Atlantic ocean fjord and is thought – there is no way of proving this – to be the source of the giant iceberg that sank the Titanic in 1912. The speed of Jakobshavn Glacier varied between 5,700 and 12,600 metres (18,700 and 41,300 ft) per year between 1992 and 2003. Currently, there’s no good way for ice scientists to measure such slow velocities in one measurement. NASA research shows that Jakobshavn Glacier, which has been Greenland’s fastest-flowing and fastest-thinning glacier for the last 20 years, has made an unexpected about-face. Jakobshavn Isbrae in Greenland is generally considered to be the fastest glacier in the world, with speeds of up to 40 metres per day. Many glaciers in Greenland and in the Antarctic Peninsula are accelerating, which is generally attributed to warmer conditions and more meltwater lubricating the bed of the glacier. The speed of Greenland's fastest glacier, Jakobshavn Isbræ, has varied substantially since its speed-up in the late 1990s. Warmer climate conditions means thinner cover on shallow lakes and a smaller fraction that freeze entirely during the winter months. The Jakobshavn glacier is Greenland’s fastest-flowing glacier. Slide a wooden block across a table or desk. Greenland's Jakobshavn glacier dumps more water into the ocean in a day than New York City uses in one month, and that rate is double what it was merely a decade ago. What Is The Main Thing Keeping People Divided and Stuck? Jakobshavn Isbræ, which is widely believed to be the glacier that produced the large iceberg that sank the Titanic in 1912, drains the Greenland ice sheet into a deep ocean fjord on the coast of the island. “With the additional speed it will likely contribute a bit more than this over the next decade.”. “We are now seeing summer speeds more than 4 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,” says Ian Joughin, a researcher at the Polar Science Center, University of Washington and lead-author of the study. The team is composed of Ian Joughin, Benjamin E. Smith and David E. Shean from the University of Washington, Seattle, US, and Dana Floricioiu from the German Aerospace Center (DLR), Weßling, Germany.
