They make great gifts. The Pine Island Glacier is one of Antarctica's largest ice streams, located south of the Hudson Mountains on West-Antarctica. Evolution of the cracks in the Pine Island Glacier. While this outlet glacier is just one of many around the perimeter of Antarctica, data collected from the ground, air, and space confirm that Pine Island is worth extra attention. Sometime between November 9 and November 11, 2013, a large iceberg separated from the front of Pine Island Glacier. Here we take advantage of several remotely sensed data sets to model the changes in speed of Pine Island Glacier, Antarctica, over nearly two decades, using a variety of existing friction laws. The Copernicus Sentinel-1 and Sentinel-2 satellites have revealed new cracks, or rifts, in the Pine Island Glacier—one of the primary ice arteries in the West Antarctic Ice Sheet. Press release issued: 27 January 2020. The Copernicus Sentinel-1 and Sentinel-2 satellites have revealed new cracks, or rifts, in the Pine Island Glacier – one of the primary ice arteries in the West Antarctic Ice Sheet. 7, 10 APRIL 2019 1059 Figure 3. a, Pine Island glacier on 18 September 2017. b, On 21 September 2017, the rift is seen unaffected. Antarctica's mighty Pine Island Glacier (PIG) is now very probably in a headlong, self-sustaining retreat. Pine Island Glacier, the longest and fastest flowing ice stream in the Antarctic, is now very probably in a headlong, self-sustaining retreat, say scientists. The behemoth measured 42 kilometers long and 17 kilometers wide, an area of 714 square kilometers. Photo by Mario Tama/Getty Images. Researchers found that while the tearing of Pine Island Glacier's shear margins has been documented since 1999, their satellite imagery shows that damage sped up dramatically in 2016. Leave a Comment / Uncategorized. You have probably noticed that each iceberg has the letter “B,” in its name. That fear has driven a big push by international teams of researchers to understand what’s going on at Thwaites and nearby Pine Island Glacier. While there tends to be more sea ice at this time of year, it is no match for the huge stresses within the massive ice shelf. Satellite observations of the Pine Island Glacier, often shortened to PIG, show a giant iceberg breaking into smaller pieces that scientists at the … (It is possible that the calving occurred one day prior, but clouds prevented a clear look.) The Pine Island Glacier in West Antarctica fascinates scientists worldwide and is the hotspot for glaciologists and climate researchers who try to understand the melting of the West Antarctic ice sheet. Thinning can destabilize the shelf because the ice loses contact with points on the ocean floor that strongly influence its grounding or stability. The map – created using integrated radar observations from a consortium of international satellites – shows glaciers flowing thousands of miles from Antarctica’s deep interior to its coast. The tipping points and early-warning indicators for Pine Island Glacier, West Antarctica ... 2010; Park et al., 2013 , Gudmundsson et al., 2019). Notes From the Field: Pine Island Glacier 2011. 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. Notice that there are times when the front appears to stay in the same place or even advance, though the overall trend is toward retreat. Un iceberg géant qui s'est rapidement disloqué en de nombreux fragments. It is possible that these fractures could spawn a new iceberg in 2019. But once again, the calving might have happened some days before under cloud cover. The Pine Island Glacier is located around 1,600 miles from the tip of South America. Pine Island Glacier glaciological and oceanographic setting. In August 2015, the U.S. National Ice Center reported that a calving event had occurred in the darkness of winter, likely in late July. Iceberg B-46, with an area of around 225 square kilometers, broke off from the Pine Island Glacier in 2019. 35 . : Past water flow beneath Pine Island-Thwaites glaciers 1961 Park), located within 200km of the present-day margins of Pine Island and Thwaites glaciers. Posted February 13, 2020 15:06:44 Radar imagery from May 19, 2019 showed large rifts forming in the Pine Island Glacier. If icebergs calve off at a rate that matches the glacier’s acceleration, the ice front stays in the same place. Pine Island Glacier (PIG), in the West Antarctic Ice Sheet, has an area of 175,000 square kilometres and loses about 45 billion tons of ice each year. Surface mass balance (SMB) is the net input of mass on a glacier's upper surface, composed of snow deposition, melt and erosion processes, and is a major contributor to the overall mass balance. Ice-shelf changes in Pine Island Bay, Antarctica, 1947–2000. The cracks are about 20 kilometers long, and up to 300 meters wide. The behemoth measured 42 kilometers long and 17 kilometers wide, an area of 714 square kilometers. Animated gif of thinning of Pine Island Glacier University of Bristol . This photo, shot by NASA science writer Kate Ramsayer during a research flight on November 7, 2018, shows sea ice between Pine Island Glacier and the newly calved Iceberg B-46. 116, NO. Spectacular! Around this time, Pine Island Glacier started to shed smaller icebergs more frequently. Here’s the 12-mile-long (20-km-long) crack in Pine Island Glacier, via ESA. , 122 (5–6), 714 – 726 (doi: 10.1130/B26417.1) Joughin, I and 6 others (2009) Basal conditions for Pine Island and Thwaites Glaciers, West Antarctica, determined using satellite and airborne data. But over the long term at Pine Island, you can see that the ice front has retreated inland, which means the calving rate has increased more than the glacier has accelerated. The acceleration stretches the glacier, causing the thinning and likely making the ice more prone to crevassing (cracking) “upstream.”. Researchers monitoring satellite imagery of the Pine Island Glacier (PIG), in west Antarctica, first noticed two large rifts forming in the shelf in 2019. It was mapped by the United States Geological Survey (USGS) from surveys and United States Navy (USN) air photos, 1960–66, and named by the Advisory Committee on Antarctic Names (US-ACAN) in association with Pine Island Bay. The two large rifts were first spotted in early 2019 and have each rapidly grown to approximately 20 km in length. The cracks, like the one visible in this image from March 8, 2015, were a precursor to further retreat of the ice front. This image shows two cracks in the Pine Island Glacier seen by the Copernicus Sentinel-2 satellite on September 14, 2019. The image above shows the iceberg on November 11, 2001. Story by Kathryn Hansen. At the end of October 2018, the European Space Agency’s Sentinel-1 satellite observed the glacier letting go of a huge chunk of ice. Download. De plus de 300 km2, soit à peu près la taille de l'île de Malte. An image from MODIS on the Aqua satellite first showed Iceberg B-27 on September 28, 2007. A science communicator and educator since 1976, Byrd believes in science as a force for good in the world and a vital tool for the 21st century. NASA Earth Observatory image by Lauren Dauphin, using MODIS data from NASA EOSDIS/LANCE and GIBS/Worldview. The animation below comes from NASA research, and was released in 2011. It’s one of the primary ice arteries in the West Antarctic Ice Sheet, yet it’s known to be thinning, accelerating in its already-fast flow, and also receding back landward from the Amundsen Sea, which is part of the Southern Ocean encircling the Antarctic continent. All observations (November 2018 - February 2019) are made available through the data portal and the Mission Exploitation Platform (MEP) so users can play around with the data using all available tools. Landsat 8 captured this view on November 13, 2013. Order now. Although it is rather remote, PIG and its twin glacier, Thwaites, are … He said in a statement: These new rifts appeared very soon after last year’s major calving of iceberg B46. It shows the evolution throughout 2019 of two large cracks in Pine Island Glacier in Antarctica. Avec son voisin le Pine Island, ce glacier forme une sorte de rempart qui, relâché à la mer, pourrait à lui seul faire monter le niveau des océans dans le monde d'au moins 65 cm. Using the latest satellite technology from the European Space Agency (ESA), scientists from the University of Bristol have been tracking patterns of mass loss from Pine Island – Antarctica’s largest glacier. NASA Earth Observatory image by Holli Riebeek, using Landsat data from the U.S. Geological Survey. It was approximately 87 square miles (226 sq km) in size. It shows the evolution throughout 2019 of two large cracks in Pine Island Glacier … Am. Une vaste cavité sous le glacier Thwaites en Antarctique Ouest a été repérée par la NASA.Mesurant 10 km de long, 4 km de large et 300 m de hauteur, cette cavité s’est ouverte à la base du glacier entre 2011 et 2016, séparant la glace du socle rocheux ouvrant la voie aux eaux chaudes provenant de l’océan et en le faisant fondre par en-dessous. NASA Earth Observatory animation by Lauren Dauphin, using MODIS data from NASA EOSDIS/LANCE and GIBS/Worldview. | Ice streams of Antarctica with Pine Island Glacier and Thwaites glacier highlighted, via AntarcticGlaciers.org. Pine Island Glacier May 2019. Press release issued: 27 January 2020. Scientists think the change in calving frequency is likely related to the thinning of the ice shelf. PROBA-V will observe Antarctica till the end of February 2019. 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. Sentinel-1 winter monitoring of their progressive extension signals that a new iceberg of similar proportions will soon be calved. NASA Earth Observatory image by Joshua Stevens, using Landsat data from the U.S. Geological Survey. Posted February 13, 2020 15:06:44 Radar imagery from May 19, 2019 showed large rifts forming in the Pine Island Glacier. National/Naval Ice Center. Scientists often use radar and thermal imagery to get a better look under these less-optimal conditions. The new rifts appeared soon after last year’s major calving of iceberg B46, which is about 3 times the size of New York’s Manhattan island. Earth Matters: A Little More on That Ice Rift in Antarctica…. Activité volcanique. It’s the first complete map showing the speed and direction of ice flow in Antarctica. Since the 1990s, the glacier has thinned by about 1.5 metres per year and its flow into the sea has increased. Operation IceBridge - Pine Island Glacier.

), Instead, Lhermitte’s model is an attempt to incorporate ice sheet damage into similar global climate models that predict both sea level rise and the future of Antarctica’s glaciers. As our earthly satellites have looked on, since the 1990s, calving events have occurred in 1992, 1995, 2001, 2007, 2011, 2013, 2015, 2017 and 2018. That was about to change. The berg had an area of 185 square kilometers. As anticipated, Pine Island Glacier, known as PIG for short, in Antarctica has just spawned a huge iceberg. Even if … More recently, calving has occurred on a near-annual basis and the bergs tend to break up more easily into smaller pieces. Bathymetric controls on calving processes at Pine Island Glacier. The Pine Island Glacier ice shelf now has one of the fastest rates of ice-shelf thinning in Antarctica. Check out some photographs from that flight here. Most people will never see Pine Island Glacier in person. Models of ice sheet evolution depend strongly on their selection of the basal friction law (Brondex et al., 2017, 2019; Joughin, Smith, ... For this study, we simulated the transient response of Pine Island Glacier (PIG) constrained by observations to evaluate a variety of friction laws. Decades of investigations have given scientists a better idea of the quirks of PIG’s behavior. A rift in the glacier first became visible on September 10, 2000, in images from NASA’s new Terra satellite, but the cracking probably started in the darkness of austral winter. Unlike previous cracks, these originated from the center of the glacier and propagated outward toward the margins. One area of particular concern is the Amundsen Sea region. Using the latest satellite technology from the European Space Agency (ESA), scientists from the University of Bristol have been tracking patterns of mass loss from Pine Island – Antarctica’s largest glacier. Jordan, TA and 6 others (2010) Aerogravity evidence for major crustal thinning under the Pine Island Glacier region (West Antarctica) Geol. Story by Kathryn Hansen. Bindschadler explained that a shrinking outlet glacier is usually doing three things: thinning (mostly at the seaward edge), retreating, and accelerating. Bull. The U.S. National Ice Center assigns names to sizeable icebergs depending on the quadrant of Antarctica in which the berg was first sighted. Polar Geospatial Center at the University of Minnesota, Moderate Resolution Imaging Spectroradiometer. Flight Center, NASA Earth Observatory (2012, February 29). The Pine Island Glacier—located at the base of the Antarctic Peninsula on the western side … The largest piece, named Iceberg B-46, spanned 226 square kilometers. Pine Island Glacier is one of many outlet glaciers around the perimeter of Antarctica, but observations have shown that this glacier is worth extra attention. The rift continued to spread across the glacier until it finally calved on November 9, 2001. Mark Drinkwater leads the Earth and Mission Sciences Division at ESA. "Being an EarthSky editor is like hosting a big global party for cool nature-lovers," she says. Large cracks are forming farther upstream from the ice front than ever before—even in the middle of the ice shelf, where scientists had never previously seen them grow. EarthSky 2020 lunar calendars are available! We find that the behavior of this glacier is simulated far more faithfully relative to observations when a “regularized Coulomb” friction law is used. ESA said on October 19, 2019, that – since the early 1990s – its ice velocity (the rate of ice flow toward the ocean surrounding Antarctica) has increased dramatically to values which exceed 30 feet (10 meters) a day. Author Topic: Pine Island Glacier (PIG) Calving and Discussion (Read 462695 times) paolo. That’s shorter than a cross-country flight from New York to Los Angeles, but there are no runways on the glacier and no infrastructure. Animated gif of thinning of Pine Island Glacier University of Bristol . Darkness engulfs the poles during winter, and in months when there is ample sunlight, clouds can obscure the view. It is possible that these fractures could spawn a new iceberg in 2019. In the case of bergs from Pine Island Glacier and others that start in the Amundsen and Eastern Ross seas, the names begin with “B”. Image development and design by Lauren Dauphin. Story by Kathryn Hansen. 2019 ). In early 2019, not long after B46 left the ice sheet, scientists spotted the additional large rifts in the glacier, shown in the video at the top of this page and in the satellite image above. Like. Pinpointing the exact birthdate of icebergs using natural color images can be a challenge. In 2014, this iceberg, 20 miles wide, broke off the tongue of the glacier and floated away. CURRENT SCIENCE, VOL. Researchers reported anomalous rifts forming between 2013 and 2015 on Pine Island Glacier. J. D. Kirkham et al. NASA Earth Observatory map by Lauren Dauphin, using Reference Elevation Model of Antarctica (REMA) data from the Polar Geospatial Center at the University of Minnesota. “The process of how a large outlet glacier like Pine Island ‘shrinks’ has some interesting twists,” said Bob Bindschadler, an emeritus NASA glaciologist who landed on Pine Island Glacier’s ice shelf in 2008. That’s a harbinger of a coming collapse—and sea level rise. That’s a harbinger of a coming collapse—and sea level rise. Recently, the frequency of Pine Island Glacier calving events has increased. It drains 5 – 10% of West-Antarctica's ice sheets and is the continent's fastest melting glacier. The animation at the top of this page shows a wide view of Pine Island Glacier (PIG) and the long-term retreat of its ice front. However, in recent times, the glacier has been experiencing calving almost yearly. Most people will never see Pine Island Glacier in person. Details Related. By October 15, fragments had already fallen below 70 square kilometers (20 square nautical miles)—the minimum size required for tracking by the U.S. National Ice Center. The pattern indicated stresses at the center of the ice shelf. That iceberg was labeled B46 by scientists. New rifts were already visible in satellite images on November 2018. Long-term measurements of West Antarctic Ice Sheet glaciers such as Pine Island are critical to understanding changes to the rate of loss of ice mass into the ocean. She has won a galaxy of awards from the broadcasting and science communities, including having an asteroid named 3505 Byrd in her honor. Le glacier de l'île du Pin, en anglais : Pine Island Glacier, est un glacier faisant partie de l'inlandsis Ouest-Antarctique en Antarctique, sur l'île du Pin. April 9, 2019. Pine Island Glacier May 2019. Deborah Byrd created the EarthSky radio series in 1991 and founded EarthSky.org in 1994. This is the conclusion of three teams that have modelled its behaviour. Photograph by European Space Agency On the ice-covered edge of a remote West Antarctic bay, the continent’s most imperilled glaciers threaten to redraw Earth’s coastlines. 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. Additional data were acquired by other UK, German, USA and Korean scientific cruises to the area between 1999 and 2019. Credit: European Space Agency. NASA Earth Observatory image by Lauren Dauphin, using Landsat data from the U.S. Geological Survey. Leave a Comment / Uncategorized. 2 Friction Law Parameterizations. Satellite images released by NASA show a mile-long (1.6km) section of the Pine Island Glacier separating from the West Antarctic Ice Sheet between 24 and 31 January. En Antarctique Ouest, un glacier grand comme la Floride, le glacier Thwaites, est en train de se détacher trop vite du continent, du fait de l’action d’eaux profondes relativement chaudes. ESA's Copernicus Sentinel-2 satellite snapped this view of cracks in the Pine Island Glacier on Sept. 14, 2019. Bottom line: ESA scientists said in October 2019 that the two new cracks in Pine Island Glacier – observed since early this year – are getting longer. We map the detailed chan-nel network and conduct a quantitative morphometric com-parison between the channels in Pine Island … Collectively, the region contains enough vulnerable ice to raise global sea level by 1.2 meters (4 feet). Down in the notoriously vulnerable ice sheet of West Antarctica, Pine Island Glacier seems to be breaking up faster than ever, and it’s looking like 2019 might be another busy year. Pine Island, Thwaites, Haynes, Pope, Smith, and Kohler hold a combined 125-cm SLE and experienced a 136 Gt/y loss in 2017, with a disproportionate contribution from Dotson and Crosson ice shelves (94% and 228% of the balance flux versus 78% for Pine Island, 44% for Thwaites, and 49% for Haynes). Until this point, large icebergs were calving from Pine Island Glacier every four to six years. If you watch, you’ll see that the sizes of Paris and New York’s Manhattan Island are also shown, to help you see the scale of the glacier’s cracks. They’re now about 12 miles (20 km) in length. The 300 m image of 19 November 2018 shows the iceberg a couple of weeks after it calved off from the Pine Island Glacier. NASA’s Operation IceBridge flew over the berg that same day. Released on December 9, 2019. Editor’s Note: Earth Observatory would like to thank the following scientists for help with image interpretation: Eric Rignot/JPL, Robert Bindschadler/NASA GSFC (emeritus), Christopher Shuman, UMBC/NASA GSFC, and Chris Readinger/U.S. In a study in which scientists from the EOC were also involved, the changes at Pine Island Glacier were examined in more detail. Images and Data for Pine Island Glacier measured between 23.05.2019 and 11.04.2020. Le glacier de l’île du Pin - ou Pine Island Glacier, affectueusement surnommé Pig, comme porc en anglais -, un glacier de l'inlandsis de l'ouest de l’Antarctique, vient de rejeter à la mer, un nouvel iceberg géant. B-35 had drifted farther from the ice front. The Pine Island Glacier—located at the base of the Antarctic Peninsula on the western side of the continent—has always shipped Antarctic ice out to sea at prolific levels, but it’s become famous in recent years due to its ever increasing output. That was about to change. Wadi Rum, Jordan - Copernicus Sentinel-2 data (2019) Wadi Rum, Jordan - Copernicus Sentinel-2 data (2019) Cracked: Pine Island Glacier Released date: Fri, 18/10/2019 - 17:15 Sub -ice -shelf melt rates are increased 80 linearly from a value that generates a steady state for the present -day glacier configuration. View Pine Island Glacier on an interactive Google map, View larger. pine island glacier 2019. Remote Sensing, Snow and Ice Pine Island Glacier is one of many Antarctic ice streams, but it’s of special interest to scientists in part because observations have shown it to be changing rapidly. Based on the numerical experiments we then evaluate early warning indicators to test for critical slowing. The calving of icebergs during the austral winter is not surprising. Moon and Venus before sunrise, Favorite photos of crescent moon and Venus. It is visible here on November 7, 2018, as observed by Landsat 8. Decline of West Antarctic Glaciers Appears Irreversible. Pine Island Glacier (PIG), in the West Antarctic Ice Sheet, has an area of 175,000 square kilometres and loses about 45 billion tons of ice each year. View All Images in This Event: Pine Island Glacier in Retreat. 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. The behemoth measured 42 kilometers long and 17 kilometers wide, an area of 714 square kilometers. Satellite monitoring suggests a new iceberg of similar proportions will soon be calved. Going fast! Pine Island Glacier is one of many outlet glaciers around the perimeter of Antarctica, but observations have shown that this glacier is worth extra attention. Published online by Cambridge University Press: 22 July 2019; Abstract. Read more: Emerging cracks in the Pine Island Glacier. The new development on the Pine Island Glacier happened just a week after a temperature record of 18.3ºC was registered in Antarctica, exceeding the previous record of 17.5ºC. As anticipated, Pine Island Glacier, known as PIG for short, in Antarctica has just spawned a huge 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. On September 28, 2017, the OLI on Landsat 8 acquired this image of the recently calved Iceberg B-44.

Two cracks in the Pine Island Glacier can be seen here in this image from September 2019 Credit: ESA The chunk that broke off over the weekend was a hefty 120 square miles in size. Pine Island Glacier, in West Antarctica, is retreating quickly. The event produced a number of sizeable icebergs including B-41, which was still close to the shelf when this image was acquired on November 26, 2015. It is possible that these fractures could spawn a new iceberg in 2019. The glacier ice streams flow west-northwest along the south side of the Hudson Mountains into Pine Island Bay, Amundsen Sea, Antarctica. Released on December 9, 2019. 3/ Here is a zoom of the animation. The Pine Island glacier is particularly unstable, and made headlines in 2017 when it lost a chunk of ice four times the size of Manhattan. Remote Sensing. They have each grown to 20km in length and could shear off a hunk of ice the size of Paris and Manhattan combined. 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.

According to NASA’s Earth Observatory, the glacier experiences “large calving events” every four to six years. The following images, acquired with Terra MODIS and the Operational Land Imager (OLI) on Landsat 8, show Pine Island Glacier’s most notable calving events over the past two decades. Pine Island Glacier (PIG) in West Antarctica has been dynamically imbalanced since the early 1990s, indicating that discharge … As the ice shelf both thins and calves enormous icebergs, the glacier discharge is unable to replenish the ice lost and the ice shelf front recedes from its previous position. The European Space Agency (ESA) released the video above on October 18, 2019. ESA created the video using satellite data from the Copernicus Sentinel-1 mission, which carries radar, and which therefore can return images from Antarctica year-round, even during the long months of continuous winter darkness.
