A comparison of these new maps with satellite images of the ice stream reveals why the glacier suddenly retreated toward the coast: at important points, it had lost contact with the ground, as the experts report in 'The Cryosphere', an online journal of the European Geosciences Union. CrossRef; Google Scholar; Wang, Xianwei Cheng, Xiao Gong, Peng Shum, C.K. Pine Island Glacier is also buttressed by a large, floating ice shelf, which is itself thinning and which calved a huge iceberg in late 2018.That iceberg was labeled B46 by scientists. Some of the evidence for this idea comes from satellite images like this one. [3], Von 1992 bis 2011 wurde auf Basis von Satellitenaufnahmen ein jährlicher Rückzug der Grounding Line um 0,95 ± 0,09 km gemessen. Pine Island Glacier: Satellite animation mid-2017 to Feb-2020 Date: February 11, 2020 Author: adrianluckman Updated animation showing the last three calving events as seen by ESA’s Sentinel-1 synthetic aperture radar. Latitude: -75° 09' 60.00" S Longitude: … Even so, when a large crack formed across the glacier in mid 2000, it was surprising how fast the crack expanded, 15 meters per day, and how soon the resulting iceberg broke off, mid-November, 2001. Why is Pine Island Glacier important? The peninsula, which juts out to the north-east of the Pine Island Glacier, is among the fastest-warming regions on the planet. Retreat of Pine Island Glacier since 1947. When one of the rifts finally became too large, the entire face of the ice shelf broke off.

In February 2017, researchers on board the German research icebreaker 'Polarstern' successfully mapped an area of seafloor previously covered by shelf ice. The West Antarctic ice sheet: behavior and environment. The Pine Island Glacier (a.k.a. In November 2015 an iceberg the size of Singapore broke off from the glacier, signaling its depreciating state. We map the detailed chan-nel network and conduct a quantitative morphometric com-parison between the channels in Pine Island Bay and the ter-restrial channels comprising the Labyrinth. This map was created by a user. Pine Island Glacier’s Newest Iceberg. Pine Island Glacier (PIG) is a large ice stream, and the fastest melting glacier in Antarctica, responsible for about 25% of Antarctica's ice loss. Drei verschiedene Simulationen für den Pine-Island-Gletscher kamen zum Ergebnis, dass sich der Pine-Island-Gletscher recht rasch weitere 40 Kilometer zurückziehen wird. Pine Island Glacier (PIG) is a large ice stream flowing west-northwest along the south side of the Hudson Mountains into Pine Island Bay, Amundsen Sea, Antarctica. The fieldwork is part of a scientific… Image. The story was similar, albeit less dramatic, with the iceberg that calved in 2015, breaking into several pieces just a few weeks later. Der vergletscherte Einzugsbereich hat eine Fläche von 162.300 km², die Eismassen des Gletschersystems machen rund 10 % des Westantarktischen Eisschilds aus. Diese Seite wurde zuletzt am 1. Create brand awareness by advertising on our esteemed and industry-respected Hydro International platform. It is a great way to boost corporate knowledge and to stay current on the latest news and developments in the hydrographic industry. If the melting on its underside continues, at some point the process may make the ice shelf so thin that it becomes instable; however, as the researchers report, with the ice thickness measuring approximately 400 metres at the calving front, we haven’t yet come to that point. UK scientists are about to set out for Antarctica to investigate the huge Pine Island Glacier - the stream of ice that is now contributing more to sea level rise than any other on the planet. The bathymetric maps of the seafloor in Pine Island Bay and the results of the image analyses can now be fed into computer models of the West Antarctic Ice Sheet, helping produce more accurate simulations. Pine Island Glacier (Landsat) Access Data. In the austral summer of 2012-2013 scientists and support staff spent 6 weeks camped on Antarctica's Pine Island Glacier. Pine Island Glacier drains much of the marine-based West Antarctic Ice Sheet, and it has a configuration susceptible to rapid disintegration and recession. [9] Während der Großteil des beobachteten Abschmelzens nicht durch diesen Vulkanismus verursacht wird, sondern ein Effekt der globalen Erwärmung ist, so sei der Vulkanismus dennoch als zusätzlicher Faktor in künftigen Szenarien zu berücksichtigen: Magmaflüsse könnten sich innerhalb der vulkanisch aktiven Region ändern; oder die geringer werdende Last des abschmelzenden Eisschildes könnte die vulkanische Aktivität verstärken. Don't miss the latest developments: join Hydro International! The peninsula, which juts out to the north-east of the Pine Island Glacier, is among the fastest-warming regions on the planet. Washington, DC, American Geophysical Union, 237 – 256. “The roughly 50-kilometre-long edge of the Pine Island Glacier’s ice shelf currently runs between an island to the north and another glacier to the south, which once again give the ice a bit of support,” says Jan Erik Arndt. By October, the new iceberg has completely broken away. Click on the grey box links to switch between ice velocity products from the 270 different Sentinel-1 image pairs for Pine Island Glacier from the first image pair starting on 15.11.2014 to the final pair on 22.06.2020. Click on the grey box links to switch between ice velocity products from the 257 different Sentinel-1 image pairs for Pine Island Glacier from the first image pair starting on 15.11.2014 to the final pair on 05.04.2020. In 2009, researchers sent a robot submarine beneath Pine Island Glacier’s floating ice tongue and discovered a ridge about half the size of the one off Thwaites Glacier. List of ERS-1/ERS-2 date and orbits used for Pine Island Glacier. Laut diesen Simulationen wird der jährliche Masseverlust des Gletschers, der von 1992 bis 2011 noch bei 20 Gigatonnen pro Jahr gelegen hatte, in den nächsten 20 Jahren 100 Gigatonnen pro Jahr betragen – dies entspricht einem Meeresspiegelanstieg von 3,5 bis 10 mm in diesem Zeitraum. [10][11] Schon im Jahr 1993 war auf einen möglichen Einfluss der dortigen vulkanischen Aktivität auf die Stabilität des Eisschildes hingewiesen worden.[12]. Model Pine Island Glacier Follow an example of how to create a mesh and set up the floating ice shelf of a real-world glacier Use observational data to parameterize the model Learn how to use inversions to infer basal friction and plot the results Introduction. Using the time series of satellite images for the Pine Island Glacier, the researchers were now able to test this thesis step by step. 60, p. 123. Pine Island and Thwaites glaciers. RSS-feed with news from Hydro International:www.hydro-international.com/content/rss/news, Latest articles published on Hydro International:www.hydro-international.com/content/rss/articles. Die Eisdicke des Gletschers, die auf etwa zwei Kilometer geschätzt wird, nimmt jährlich um ungefähr einen Meter ab. Researchers Map Seafloor Near Pine Island Glacier The Pine Island Glacier in Western Antarctica is not only one of the fastest-flowing ice streams in the Southern Hemisphere; over the past 11 years, four major icebergs have calved from its floating tongue. The Pine Island Glacier. Latitude: -75° 09' 60.00" S Longitude: … Images and Data for Pine Island Glacier measured between 02.04.2016 and 28.06.2020. Satellite altimetry and interferometry show that the grounded PIG thinned by up to 1.6 meters per year between 1992 and 1999, affecting 150 kilometers of the inland glacier. [2], Der Gletscher hat sich in den letzten 20 Jahren deutlich zurückgezogen. That’s slightly larger than the iceberg that previously separated from the glacier in September 2017. With a flow speed of four kilometres per year, Western Antarctica’s Pine Island Glacier is one of the fastest-flowing ice streams in the Southern Hemisphere. (b) Pine Island Glacier ice shelf draft calculated from a surface digital elevation model derived from Worldview satellite stereoscopic optical imagery [Moratto et al., 2010; Shean et al., 2016] assuming hydrostatic equilibrium. Media in category "Pine Island Glacier" The following 44 files are in this category, out of 44 total. The same area in January 2012 (not shown) showed a major break, and the November 13, 2013 (above) image shows … The Pine Island Glacier is visible stretching from the right of the image to the centre. Dabei ist zu beachten, dass der im Rückzugsgebiet zunehmend steiler abfallende Meeresboden einem Rückzug der Grounding Line eigentlich entgegenwirkt haben sollte. We flew into McMurdo Station on 17 November, and were able to get through all the check-ins and field training in a couple of days. The tongue of Pine Island is shown moving inland between September 2006 and March 2007. Der beschleunigte Verlust an Mächtigkeit, der seit den 1980er Jahren beobachtet wird, wird auf subglaziales Schmelzen am Grund des Eisschelfs zurückgeführt, welches sich durch die kürzliche Intensivierung der Zirkulation des Zirkumpolaren Tiefenwassers verstärkt hat. Während im Jahr 2010 der Gletscher ungefähr 69 Kubikkilometer Eis als Schmelzwasser ins Meer transportierte, gab er 2012 mit etwa 35 Kubikkilometern nur etwa die Hälfte an Schmelzwasser ab. Pine Island Glacier Data Set Map Midpoint location for each velocity vector in the data set, plotted on December 18, 1988 Landsat image. In den folgenden Jahren bleibt der Masseverlust laut diesen Simulationen auf hohem Niveau von 60 bis 120 Gigatonnen pro Jahr. Most people will never see Pine Island Glacier in person. Simulationen einer im Jahr 2014 erschienenen Studie legen nahe, dass sich der Rückzug aufgrund des Reliefs am Meeresgrund in den nächsten Jahren deutlich verstärkt, was einen noch fünf Mal so großen jährlichen Masseverlust zur Folge hat. Together with its neighbouring glaciers, every year the up to 50-kilometre-wide ice stream transports more than 300 gigatonnes of ice from the hinterland to the Amundsen Sea, and is responsible for between five and ten percent of the global sea-level rise. [3], Derzeit (2014) ist der Pine-Island-Gletscher für 20 % des Masseverlusts des Westantarktischen Eisschilds verantwortlich. Diese wurde durch die vorherrschenden östliche Winde verursacht, die durch einen starken La-Niña-Effekt bedingt waren. PIG) The area of the iceberg poised to calve off the Pine Island Glacier is about 115 square miles, or 300 square kilometers. Image Information. Die sogenannte Grounding Line, also die Linie, ab der das Eis beginnt, auf dem Meer zu schwimmen, hat sich in diesem Zeitraum um etwa 20 Kilometer in Richtung der Küste verlagert. (Courtesy of NASA) This month, an iceberg nearly the size of Atlanta broke off in Antarctica. Der Pine-Island-Gletscher (englisch Pine Island Glacier, abgekürzt PIG) ist ein bedeutender Eisstrom im Ellsworthland in Westantarktika. Pine Island Glacier drains much of the marine-based West Antarctic Ice Sheet, and it has a configuration susceptible to rapid disintegration and recession. That must be what happened during a calving event in 2007. [2] Der Pine-Island-Gletscher erstreckt sich vom Hudson-Gebirge bis zur Pine Island Bay in der südlichen Amundsen-See, wo er einen Eisschelf bildet. As a first application, we shall derive an elevation map of Walgreen Coast, Antarctica, the region that encompasses Pine Island Glacier, from GLAS data. With the aid of multibeam echosounders, Arndt and his colleagues were able to precisely map the seafloor. Tonnen Eis. Find local businesses, view maps and get driving directions in Google Maps. In the austral summer of 2012-2013 scientists and support staff spent 6 weeks camped on Antarctica's Pine Island Glacier. Presence of one currently erupting subglacial volcano beneath the Pine Island Glacier . Images and Data for Pine Island Glacier measured between 05.10.2015 and 11.04.2020. Maps for all. Der Pine-Island-Gletscher (englisch Pine Island Glacier, abgekürzt PIG) ist ein bedeutender Eisstrom im Ellsworthland in Westantarktika. Here we use speckle tracking to derive a subannual resolution record of the grounding zone position from 2009 to 2015, following the glacier's recent speedup. Pine Island Glacier’s Newest Iceberg. Researchers on board the German research icebreaker 'Polarstern' successfully mapped an area of seafloor previously covered by shelf ice. "Older maps suggested a shallower canyon, … Simply search for Hydro International and fill in the article you are looking for. Location map of Pine Island and Thwaites glaciers, in West Antarctica. In the older images, rises in the ice’s surface can be identified at precisely those points where the peaks of the ridge are directly under the ice shelf. The Pine Island glacier has retreated roughly 50 kilometers in the past 70 years. Strong, positive awareness acts like a magnet that puts customers on a fast track to purchase. Weather maps produced by aq.freemeteo.com. Velocity data were derived from the Landsat scenes listed below. NASA Earth Observatory animation by Lauren Dauphin, using MODIS data from NASA EOSDIS/LANCE and GIBS/Worldview. The Cryosphere 2018. A second, applied objective is to map elevation changes in Pine Island Glacier, a glacier that plays a key role in the question of stability of the West Antarctic Ice Sheet and has been changing rapidly in recent years. In the older images, rises in the ice’s surface can be identified at precisely those points where the peaks of the ridge are directly under the ice shelf. In addition to the two researchers from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research a member of the British Antarctic Survey and experts from the German Aerospace Center (DLR) took part in the new study. (Antarctic Research Series 77.) The Pine Island Glacier in Western Antarctica is not only one of the fastest-flowing ice streams in the Southern Hemisphere; over the past eleven years, four major icebergs have calved from its floating tongue. The Landsat satellite acquired the image on January 13, 2001. M. Holland, David and Li, Xiaowen 2014. Normalerweise sind in diesem Gebiet westliche Winde vorherrschend. Die Vergangenheit hat gezeigt, dass eine solche Konstellation zur Destabilisierung von Gezeitengletschern führen kann. The glacier is one of the main pathways for ice entering the Amundsen Sea from the West Antarctic Ice Sheet, and is one of the fastest-retreating glaciers in Antarctica. The Pine Island Glacier (PIG) transports 69 cubic kilometers of ice each year from ∼10% of the West Antarctic Ice Sheet (WAIS). Der Gletscher gilt als destabilisiert; im Jahr 2017 ist seine Fließgeschwindigkeit auf 2,5 Meilen pro Jahr gestiegen. View Pine Island Glacier in a larger map. Also in May 2007, a crack in Pine Island becomes visible. Raw Images. (Courtesy of NASA) This month, an iceberg nearly the size of Atlanta broke off in Antarctica. Alfred-Wegener-Institut Helmholtz-Zentrum für Polar- und Meeresforschung Stabsstelle Kommunikation und Medien Am Handelshafen 12 27570 Bremerhaven Scale: lines x samples = 86km x 90km. Image. In the older images, rises in the ice’s surface can be identified at precisely those points where the peaks of the ridge are directly under the ice shelf. Juli 2013 zur Bildung eines Eisbergs mit einer Fläche von rund 720 km², der in die Amundsen-See trieb. Pro Jahr verliert der Gletscher 45 Mrd. [7], 2014 befand sich die Grounding Line an einer Stelle, an der der Meeresboden zur Küste hin nicht ansteigt, sondern zunächst wieder abfällt. The January 2011 Landsat satellite imagery (not shown) showed a series of splits along the western edge of the glacier. The Pine Island Glacier’s more than 400-metre thick ice shelf must have been grounded on the ridge for several decades, as the satellite images of the glacier gathered by the researchers – dating back to 2002 – confirm. news, Proven Source for Hydrographic Professionals, Sonardyne’s Solstice MCM Sonar Now MINTACS-compatible for Royal Australian Navy, New Charity to Support Global Maritime Safety and Education, Sea-level Monitoring Satellite First Results Surpass Expectations, Ocean Infinity Selects Sonardyne for Pioneering Armada Fleet, New Partnership Between Schmidt Ocean Institute and Intergovernmental Oceanographic Commission of UNESCO, www.hydro-international.com/content/rss/news, www.hydro-international.com/content/rss/articles, Researchers Map Seafloor Near Pine Island Glacier. Annals of Glaciology, Vol. David G. Vaughan, Hugh F. J. Corr, Fausto Ferraccioli, Nicholas Frearson, Aidan Located near the base of the Antarctic Peninsula—the “thumb” of the continent—the glacier lies more than 2,600 kilometers (1,600 miles) from the tip of South America. Pine Island Glacier is one of the fastest-retreating glaciers in Antarctica. When an ice shelf loses contact with such obstacles (known as “pinning points”), the ice stream reacts as if someone had suddenly released a giant brake. Satellite Image ID # Path/Row Date Acquired; Landsat 5: 5001113008635510: 01/113: 21 December 1986: Landsat 4 : 4001113008835310: 01/113: 18 … 18]). [3] Eine weitere im Jahr 2014 veröffentlichte Studie machte deutlich, dass der Pine-Island-Gletscher sehr sensitiv auf Klimaveränderungen reagiert. Pine Island Glacier — Last month it was discovered that a large iceberg had recently separated from the calving front of Antarctica’s Pine Island Glacier. Maps for all. According to the U.S. National Ice Center, this iceberg, named B-46, has an area of 87 square miles. Figure 1Overview map displaying the location of features and regions referred to in the text.The catchment drained by contemporary Pine Island and Thwaites glaciers is highlighted in green. [4] Man geht davon aus, dass die Schmelzvorgänge im Meer und das Ausdünnen des Eisschelfs dazu führen, dass das Gletscherende dem Eisstrom weniger Widerstand entgegensetzt und somit ebenfalls für das Ausdünnen des kontinentalen Teils des Gletschers verantwortlich ist. Find more information on www.geo-matching.com! The catchments of Pine Island Glacier and Thwaites Glacier in the Amundsen Sea Embayment are two of the largest, most rapidly changing, and potentially unstable sectors of the West Antarctic Ice Sheet. With nothing left to stop them, the ice masses rapidly flow out to sea – at least that’s the theory. 53, Issue. The Pine Island Glacier in Western Antarctica is not only one of the fastest-flowing ice streams in the Southern Hemisphere; over the past 11 years, four major icebergs have calved from its floating tongue. [5], Im Oktober 2011 zog der Gletscher die Aufmerksamkeit auf sich, als sich 20 km hinter der Kalbungsfront ein etwa 30 km langer Riss im Schelfeis gebildet hatte. Da der Gletscher in den letzten Jahren eine deutlich negative Massenbilanz aufwies, ist dieser Beitrag gestiegen. The Pine Island Glacier is located around 1,600 miles from the tip of South America. As such, our Polarstern expedition in February 2017 was an unprecedented opportunity to map 370 square kilometres of an area that had previously largely been covered by the Pine Island Glacier’s ice shelf,” explains first author Dr Jan Erik Arndt from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) in Bremerhaven. August 2020 um 09:48 Uhr bearbeitet. Scientists think that the glacier is shrinking because the ocean water that flows under the glacier is warming, increasing melt at the base. Brand awareness can affect every stage of the purchase funnel. The catchments of Pine Island Glacier and Thwaites Glacier in the Amundsen Sea Embayment are two of the largest, most rapidly changing, and potentially unstable sectors of the West Antarctic Ice Sheet. Iceberg B-49 calved from the Antarctic glacier in February 2020. O’Hare, Dieter Mach, John W. Holt, Donald D. Blankenship, David L. Morse, Duncan A. Much to their surprise, in the process they determined that submarine highs not only stabilise ice shelves like giant brakes; in some cases, these mountains can also set off calving events – for instance, when the calving front advances, causing it to crash into a mountain with full force. Get permission to reuse our content quickly and easily with PLS Permissions Request. But for most of the ice shelves in the Antarctic, we know very little about the features of the underlying seafloor. The Pine Island Glacier is buttressed only by its own floating terminus, wedged between ice walls; the Thwaites Glacier is not buttressed by an ice shelf at all. One of the best‐mapped grounding lines is that of Pine Island Glacier (PIG), where the relationship between grounding line retreat and flow speed is well established. In a comparison with a map of the same area based on ERS-1 data, we will investigate the mapping capabilites of GLAS for different glacio-morphologic units (section 4).
