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. 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. (Courtesy of NASA) This month, an iceberg nearly the size of Atlanta broke off in Antarctica. View the forecasted snow maps for the region around Pine Island Glacier. August 2020 um 09:48 Uhr bearbeitet. In Alley, R. B. and Bindschadler, R. A. eds. Drei verschiedene Simulationen für den Pine-Island-Gletscher kamen zum Ergebnis, dass sich der Pine-Island-Gletscher recht rasch weitere 40 Kilometer zurückziehen wird. They are also neighboring outlets, separated by the topographically unconfined eastern shear margin of Thwaites Glacier and the southwest tributary of Pine Island Glacier. Diese Seite wurde zuletzt am 1. The new maps of the ocean floor in Pine Island Bay, which is predominantly 800 to 1,000 metres deep, reveal a previously unmapped submarine ridge and two mountains, the peaks of which reach up to a water depth of 370 metres. With nothing left to stop them, the ice masses rapidly flow out to sea – at least that’s the theory. 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. Pine Island Glacier glaciological and oceanographic setting. Global Maps; Articles; Blogs; EO Explorer; Pine Island Glacier in Retreat. (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.

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. By October, the new iceberg has completely broken away. David G. Vaughan, Hugh F. J. Corr, Fausto Ferraccioli, Nicholas Frearson, Aidan The Cryosphere 2018. 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. The Pine Island Glacier is visible stretching from the right of the image to the centre. As the satellite images show, back then the edge of the Pine Island Glacier’s ice shelf collided with one of the newly discovered mountains, hitting it so hard that rifts formed in the surface of the ice. View Pine Island Glacier in a larger map. Washington, DC, American Geophysical Union, 237 – 256. Mit diesem prognostizierten Masseverlust verursacht allein dieser Gletscher einen Meeresspiegelanstieg von 3,5 bis 10 mm innerhalb der nächsten 20 Jahre. To view image data select Velocity Map or Data Set Map, or use the links on the overview image. Tonnen Eis. The January 2011 Landsat satellite imagery (not shown) showed a series of splits along the western edge of the glacier. Brand awareness can affect every stage of the purchase funnel. The Pine Island Glacier is located around 1,600 miles from the tip of South America. Velocity data were derived from the Landsat scenes listed below. Pine Island Glacier Data Set Map Midpoint location for each velocity vector in the data set, plotted on December 18, 1988 Landsat image. Watch the glacier’s ice front as it retreats and sheds some notable icebergs over the past two decades. Observations from geophysical surveys and long-term oceanographic instruments deployed down bore holes into the ocean cavity reveal a buoyancy-driven boundary layer within a basal channel that melts … Pine Island Glacier’s Newest Iceberg. Pine Island Glacier (Landsat) Access Data. 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. Damit ist der Gletscher, was den Gesamtmasseverlust betrifft, auch der am stärksten schwindende weltweit. 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. 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. Stay tuned for the latest approaches to hydrographic data acquisition and processing, with a special focus on automatization and digitalization. Scale: lines x samples = 86km x 90km. [3] Eine weitere im Jahr 2014 veröffentlichte Studie machte deutlich, dass der Pine-Island-Gletscher sehr sensitiv auf Klimaveränderungen reagiert. Pine Island Glacier map - mobile. Die Pine Island Bay ist eine 48 km breite und etwa 64 km lange Bucht an der Walgreen-Küste des ostantarktischen Marie-Byrd-Lands.Der Pine-Island-Gletscher mündet in diese Bucht.. Luftaufnahmen der US-amerikanischen Operation Highjump (1946–1947) aus dem Jahr 1946 dienten 1955 dem US-amerikanischen Kartografen Gardner „Gard“ Dean Blodgett (* 1925) der Kartierung der Bucht. [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. Most people will never see Pine Island Glacier in person. It is possible that a retreat of the PIG may accelerate ice discharge from the WAIS interior. [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. [2], Der Gletscher hat sich in den letzten 20 Jahren deutlich zurückgezogen. [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. Just ask! 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. Die Abbruchskante verschiebt sich seit langem immer mehr in Richtung Land. The fieldwork is part of a scientific… 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.

NASA Earth Observatory animation by Lauren Dauphin, using MODIS data from NASA EOSDIS/LANCE and GIBS/Worldview. Annals of Glaciology, Vol. Pine Island and Thwaites glaciers. 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. The black box shows the portion of the Transantarctic Mountains (TAM) containing Wright Valley, the Royal Society Range, the Convoy Range, and the Asgard Range, in which channel features have been observed. That must be what happened during a calving event in 2007. View Pine Island Glacier in a larger map. 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. Global Maps; Articles; Blogs; EO Explorer; Pine Island Glacier in Retreat. Die Eisdicke des Gletschers, die auf etwa zwei Kilometer geschätzt wird, nimmt jährlich um ungefähr einen Meter ab. Der vergletscherte Einzugsbereich hat eine Fläche von 162.300 km², die Eismassen des Gletschersystems machen rund 10 % des Westantarktischen Eisschilds aus. In February 2017, researchers on board the German research icebreaker Polarstern successfully mapped an area of seafloor previously covered by shelf ice. 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. Then in 2015, a calving event shifted the edge of the ice shelf 20 kilometres nearer the coast and reduced the floating ice tongue’s total area to roughly 470 square kilometres. As a result, the ice tongue, which is currently ca. Also in May 2007, a crack in Pine Island becomes visible. Maps for all. Find local businesses, view maps and get driving directions in Google Maps. “The direction and speed of a given glacier’s flow chiefly depend on the topography of the ground below it. The largest piece became caught on the submarine ridge for nearly a year, turning clockwise over and over again until the combination of ocean currents, wind and melting broke it loose. [5], 2015 und 2017 brachen zwei weitere große Eisberge von Eisschelf ab. Media in category "Pine Island Glacier" The following 44 files are in this category, out of 44 total. Strong, positive awareness acts like a magnet that puts customers on a fast track to purchase. Learn how to create your own. Scientists have already identified the cause of this rapid loss of ice: since the 1940s, warm water masses, which branch off from the Antarctic Circumpolar Current, have found their way beneath the floating part of the glacier, melting what is referred to as its ice shelf from below.
