Currently, Thwaites' ice loss contributes approximately 4% to the annual rise in global sea-levels, with the potential to add 65cm in total should the whole glacier collapse. This ice mass has also been labelled as the “world's most dangerous glacier” because it holds enough ice to raise the world oceans more than two feet. Notice the size of the glacier’s main ice tongue in 2001, when the glacier was advancing by about 4 kilometers per year. 1) and 2 modeling projects (red open circles in Fig. Its grounding line – the separation between the ice sheet that is attached to the bedrock and the floating ice shelf – has retreated by 14 km between 1996 and 2011 (more details about the importance of the grounding line in this post). The example above illustrates only one of the results that have already been obtained as part of the ITGC program framework. 12. 2017, Global & Planetary Change. 1). See the copyright page for more information. 17. West Antarctica’s Thwaites Glacier is the size of Florida. Assuming the last 4 years lost ice at the same rate gives a total of 1068 Gt.). Scambos et al. The Thwaites Glacier in … The impact of thinning ice shelves on glacier flow had already been suggested (see this study for example), but PROPHET allowed the first quantification of this process through the combined use of an ice-sheet model and satellite observations. Thwaites Glacier ice loss currently contributes around 4% of all global sea-level rise (assuming 3.5 mm annual sea-level rise) and has the potential to contribute significantly more. A few weeks before the conference, I visited Anandakrishnan at Penn State. (Source and calculation: https://data1.geo.tu-dresden.de/ais_gmb/ Over the 14 year period of 2002–2016, Basin AIS21, which is slightly larger than just TG, has lost 748 Gt, equating to 2.07 mm of global sea level compared to a current rate of global sea level rise of 3.2 mma-1=4.6%. 50 billion tonnes assumes 4% of 3.5 mm annual sea-level rise. (Sources: Mouginot et al., 2014, Geophysical Res. West Antarctica’s Thwaites Glacier has covered 70,270 square miles, almost the approximate size of Florida. Thwaites Glacier is roughly the size of UK (176 x10 3 km 2). Its fastest flowing grounded ice is centred between 50 and 100 km east of Mount Murphy. ( 2019). Fig. This material is based upon work supported by the National Science Foundation under grant number NSF-PLR 1738913, and reviewed by NSF. (2019). The Thwaites Glacier in … Figure 2: Map of Antarctica showing the changes in ice velocity (modeled changes in % due to observed ice-shelf thinning, in colors) and changes in ice mass (red circles mean ice loss and blue circles mean ice gain) due to ice-shelf thinning between 1994 and 2012. The researchers found that the thinning of the floating ice shelf of Thwaites Glacier (and other glaciers in West Antarctica) instantaneously impacts the speed of ice flow via a loss of buttressing (see this post for an explanation of buttressing), which leads to sea-level rise. The flow speed of Thwaites has been increasing, while inland snowfall has not changed significantly. It has also been dubbed the doomsday glacier. At 74,000 square miles, the glacier is roughly the same size as Florida and is particularly susceptible to climate and ocean changes, according to the International Thwaites Glacier Collaboration. Figure 1: Map showing the location of Thwaites Glacier in West Antarctica, as well as the main geographic focus of the 8 projects involved in the International Thwaites Glacier Collaboration (ITGC). Ice surface speeds exceed 2 km annually (1.2 miles annually) near its grounding line. The 5-year collaboration is costing an estimated $50M. If Thwaites in Antarctica, which is around the size of Florida or Great Britain, were to collapse, it could lead to an increase in sea levels of around 25 inches (65 centimetres). The first sighting of the coastline in this area of Antarctica was in 1940, as part of the third Byrd expedition. 4. 11. I also recommend that you have a look at the Thwaites Explorer, which is an interactive visualization tool providing details about how and why the glacier is changing, and how this affects global sea level. (Source: Scambos et al. Warming of the atmosphere and ocean and their interaction with the glacier are driving the change. It was initially delineated from aerial photographs collected during Operation Highjump in January 1947. This is the last in a series, Into the Thaw: Decoding Thwaites Glacier. The Thwaites glacier in Antarctica is massive - roughly the size of Great Britain. November 10, 2011 ... his description of flying nine parallel flight tracks at only 1,500 feet altitude over the Thwaites Glacier. Thwaites Glacier in Antarctica is 74,000 square miles, the size of Great Britain, and is thought to be particularly susceptible to climate change. It's a giant mass of more than 192,000 square kilometers (74,000 square miles) -- an area similar in size … In the last decade, huge chunks of the glacier calved away in 2011, 2013, 2015, 2017, 2018 and now in 2020. West Antarctica’s Thwaites Glacier is located in one of the most remote places on earth and just so happens to be about the size of the State of Florida. West Antarctica’s Thwaites Glacier has covered 70,270 square miles, almost the approximate size of Florida. The Thwaites glacier is 74,000 square miles, roughly the size of the UK. However, statements or recommendations expressed here are those of the authors, and do not necessarily reflect the views of the National Science Foundation. WIRED's January cover story is taking readers to Antarctica's Thwaites Glacier. Thwaites Glacier. NASA discovered an underwater cavity underneath the glacier, with an area two-thirds the size of Manhattan in January 2019. 2017, Global & Planetary Change, It is larger than England, Wales and Northern Ireland put together (England, Wales and Northern Ireland have a combined area of 164,000 km, And roughly the size of the island of Britain (Great Britain is 209,000 km, It is larger than US state of Florida (Florida covers an area of 170,000 km. 1. Back in 1990s, the glacier was losing around 10 billion tonnes of ice each year. In this context, the largest Earth Science funding agencies in the UK and US, namely the Natural Environment Research Council (NERC) and the National Science Foundation (NSF), have teamed up to set up a 5-year collaboration program that started in 2018, the International Thwaites Glacier Collaboration (ITGC). Lett., Gardner et al., 2018, The Cryosphere (using Landsat)), 14. Thwaites, about the size of Florida, is currently responsible for about 4 percent of global sea level rise, making it one of the most dangerous glaciers in the world, according to scientists. With the West Antarctic Ice Sheet currently losing ice at a fast pace, leading to sea-level rise, it is very important to better understand the processes by which this ice melting occurs. But it’s receding by about half a mile per year. (Source: Google Earth; Rothera to mid-grounding line of Thwaites Glacier = 1588 km; McMurdo to mid-grounding line of Thwaites Glacier = 2050 km), 6. (Calculation: 100-km wide front, ~1000 meters thick, 5km/yr, 50 years = ~7 cm), 9. The focus is Thwaites Glacier, which is roughly the size of Florida and sits on the western edge of Antarctica.

How much, how fast? Thwaites Glacier covers 74,000 square miles—an area the size of Florida—and is particularly susceptible to climate and ocean changes. ITGC consists of eight science projects, six are field-work oriented, and two are focused on modeling of glacier processes and its recent and future evolution. Cavity roughly two-thirds the size of Manhattan is growing under Thwaites, described by scientists as world's most dangerous glacier, per a NASA study. We have already briefly mentioned this collaboration in a previous post, and this post will provide more hints about it. Cavity roughly two-thirds the size of Manhattan is growing under Thwaites, described by scientists as world's most dangerous glacier, per a NASA study. Thwaites Glacier is melting fast, and scientists fear its collapse could one day destabilize surrounding glaciers and eventually trigger up to 11 feet of global sea level rise. From this figure, it is obvious that the main losses in ice mass from Antarctica occur in the Amundsen Sea, where Thwaites Glacier (TWG) is located. (2017). The growing cavity sits in West Antarctica at the bottom of Thwaites Glacier, which is about as big as Florida and contains enough ice to contribute more than 2 feet to sea level rise, NASA said. Text Size. 20. If the glacier melts entirely, it could trigger a 10-foot rise in sea levels. British and American experts are launching the largest joint mission for more than 70 years to investigate how long the 113,000 square-mile Thwaites Glacier can last in its current form. ), 10. Learn more about the mission. Geophysical Research Letters. West Antarctica’s Thwaites Glacier covers 70,270 square miles (182,000 square km), the approximate size of Florida. The Thwaites Glacier is around the size of Florida, and the team of NASA-led scientists researching it had expected to find "some gaps" between the ice and bedrock. Researchers found exactly this situation at Thwaites last year, when they discovered a cavern two-thirds the size of Manhattan and nearly a thousand feet tall underneath the glacier. 5. 14 times the size of Great Britain, about the size of India, nearly twice the area of Alaska, or more than 100 times the area of Belgium.

NASA said sea levels could rise by 2 additional feet if the glacier collapses, which … 2 shows the instantaneous change in ice velocity (colors) and ice mass (circles) in Antarctica from 1994 to 2012 due to ice-shelf thinning. It holds enough ice to raise the world ocean a little over 2 feet (65 centimeters) and backstops neighboring glaciers that would raise sea levels an additional 8 feet (2.4 meters) if all the ice were lost. The goal of the ITGC program is to shed light on all these outlined processes, with the aim to better predict the fate of Thwaites Glacier. Thwaites Glacier is one of the largest and most unstable ice streams in Antarctica. If Thwaites Glacier was to collapse entirely, global sea levels would increase by 65 cm (25 in) (Source: Bedmachine, https://www.nature.com/articles/s41561-019-0510-8#Sec7, gives total volume 483,000 km3; volume above flotation 258,000 km3, and sea level equivalent, 65 cm.

If Thwaites Glacier continues to accelerate, retreat, and widen at rates consistent with recent changes, it could contribute several cm to sea-level rise by the end of the century. News. This guest post was contributed by a scientist, student or a professional in the Earth, planetary or space sciences. In this context, Thwaites Glacier is a very good case study of an accelerating glacier, which contributes substantially to sea-level rise, and for which a huge scientific collaboration effort has recently been set up. However, many more processes are at play on the glacier and in its vicinity. And its ice mass loss has doubled between 2006 and 2014. (Source: https://thwaitesglacier.org/). The focus is Thwaites Glacier, which is roughly the size of Florida and sits on the western edge of Antarctica. ), 13. Thwaites, he said, was a 120km-wide “monster glacier” that is continuing its retreat with huge future implications, because it could potentially add 0.6 metres to rising seas. Its fastest flowing grounded ice is centred between 50 and 100 km (31 and 62 mi) east of Mount Murphy on the north coast of West Antarctica. David Docquier is a post-doctoral researcher at the Swedish Meteorological and Hydrological Institute (SMHI) in Sweden. Robel, along with scientists Helene Seroussi and Gerard Roe used mathematical analysis and computer models to make projections of sea levels in the future.

Thwaites Glacier is melting fast, and scientists fear its collapse could one day destabilize surrounding glaciers and eventually trigger up to 11 feet of global sea level rise. The amount of ice loss has doubled over the last 30 years by Thwaites and its neighbouring glaciers. Indeed, Thwaites Glacier is one of the largest contributors to global sea level rise from the West Antarctic Ice Sheet. If the WAIS collapsed and melted in its entirety, global sea levels would rise by 3.3 metres; however, this process would require centuries to millennia. 3 below shows a vertical profile of Thwaites Glacier and the ocean around it with the key drivers and their effects highlighted. Collapse of the glacier would require a few centuries. Would you like to write a blog entry about your research? 19. The glacier terminus is nearly 120 km wide, and the bed of the glacier reaches to >1000 m below sea level. The ITGC program is composed of 8 different research projects and involves more than 60 scientists, divided into 6 field work projects (red solid circles in Fig. About the size of Florida, Thwaites Glacier is currently responsible for approximately 4 percent of global sea level rise.

How small changes can make a big difference: tipping points in Antarctica, Running a live stream of proglacial processes. One example of the early findings from the ITGC program is from the PROPHET modeling project (see this study). Figure 3: Vertical profile of Thwaites Glacier (white color on the left side), ocean (blue color on the right side) and bedrock (brown color on the bottom), with key drivers, processes and their effects. Did you know… that you can read the edge of Greenland’s ice as an open book? Thwaites glacier is larger the England and could drive global sea levels up by two feet (60cm) if it were to totally collapse. This ice mass has also been labelled as the “world's most dangerous glacier” because it holds enough ice to raise the world oceans more than two feet. Thwaites Glacier is part of the West Antarctic Ice Sheet (WAIS). Thus, it is important to invest scientific effort in trying to better understand the present and future behavior of Thwaites Glacier. Each ITGC project is closely linked to the overall program with the goal of advancing our understanding of the processes that control ice loss from Thwaites Glacier, and to communicate the results to the public, the wider scientific community and policymakers. 1).. Over the past 30 years, this glacier has undergone dramatic changes. TWG stands for Thwaites Glacier. At 74,000 square miles, the glacier is roughly the same size as Florida and is particularly susceptible to climate and ocean changes, according to the International Thwaites Glacier Collaboration.
