UK and US scientists are collaborating to investigate one of the most unstable glaciers in Antarctica, the Thwaites Glacier, roughly the same size as Florida or Britain… Your email address will not be published. They move up, down, and forward through the ocean by motorized internal mechanisms- oil bladders and weights which can be manipulated remotely. The instruments are tethered to a weight that sinks to the bottom of the ocean. According to NASA, the entire Thwaites Glacier, which is the size of Florida, is responsible for about 4 percent of global sea level rise and holds enough ice … The survival of Thwaites has been deemed so critical that the United States and Britain have launched a targeted multimillion-dollar research mission to the glacier. Learn more about the eight projects that are part of ITGC, © 2020 CIRES is a partnership of NOAA and the University of Colorado Boulder. That texture is created by crevassing of the ice as it moves past the grounding line. The gliders, who are named for whales (both common and famous names), are guided remotely from their institutions through satellite transmitted commands. Data collected near Thwaites Glacier in West Antarctica by scientists aboard the research ship Nathaniel B. Palmer (seen here at the site in … Rice University Thwaites Glacier today is rapidly losing mass in response to changing atmospheric and oceanic conditions. Its mission was to look for features of recent glacial retreat and measure Circumpolar Deep Water properties near the glacier front. Over the past 30 years, the amount of ice flowing out of the region has nearly doubled, and computer models show that over the next several decades, the glacier may lose ice even more rapidly. In addition to multibeam bathymetry, the THOR team collects complimentary sub- seafloor images that can reveal several meters of what lies directly below the surface. Thwaites Glacier covers 74,000 square miles—an area the size of Florida—and is particularly susceptible to climate and ocean changes. Thwaites Glacier, Antarctica, is of particular concern to scientists. Along the 150-kilometer ice front, the satellite images show two different types of ice shelves. The Thwaites glacier is 74,000 square miles, roughly the size of the UK. This is the first time since 2000 that the Palmer has been to Thwaites, with only one other more recent survey conducted by the Polar Stern in 2006. Upon reaching the eastern edge of the shelf, we gathered multibeam bathymetry and sub-bottom profiles. Glaciers appear on almost every continent. Moving west along the front (down in the image) the ice changes into what looks like alligator skin. Today, we would not be able to survey the seafloor in that sector. The Palmer mapped a new ice-free boundary that is 18 km further south than in 2006. © Copyright - Rice Department of Earth, Environmental and Planetary Sciences. This material is based upon work supported by the National Science Foundation under grant number NSF-PLR 1738913, and reviewed by NSF. The grounding line is where the glacier transitions from resting on the bedrock to a floating ice shelf in the Amundsen Sea. This first site is near what is possibly a former pinning point at the tip of the remnant Thwaites Glacier Tongue. Glaciers everywhere might be melting, but only one has earned the most terrifying nickname: the Doomsday Glacier. More than 2000 km 2 of new data were acquired immediately offshore the western Thwaites Ice Shelf in an area previously made inaccessible by … • Log In, Geophysical Habitat of Subglacial Thwaites (GHOST), Melting at Thwaites grounding zone and its control on sea level (MELT), Deep channels link ocean to Antarctic glacier, Plans for International Thwaites Glacier Collaboration in response to COVID-19, New Sights in the Second Field Season of the International Thwaites Glacier Collaboration. The International Thwaites Glacier Collaboration consists of eight projects focused on specific aspects of the glacier, and one coordinating project. Arriving around 5 a.m., the Palmer begins to map the uncharted perimeter, the multibeam simultaneously mapping the seafloor in front and as far under the shelf as the angle of the sound pulse could extend. Its melting already contributes 4% of global sea level rise and there are fears that it could become unstable and contribute many metres to global sea level. Several groups of Emperor penguins that were feeding in the water nearby observe the proceedings. Image courtesy of Johan Ronaldsson. The International Thwaites Glacier Collaboration is performing some magnificent science, conducting the most ambitious fieldwork ever undertaken at the tip of what is one of the most significant glaciers on Earth. Thwaites Glacier is one of the largest and most unstable ice streams in Antarctica. Site by, Life on the Research Icebreaker Nathaniel B. Palmer. It's a giant mass of more than 192,000 square kilometers (74,000 square miles) -- … Thwaites, if it went bad, would behave nothing like that. Phone: 713.348.4880 On the afternoon of the 21st, The Palmer began its 13-knot transit from Rothera to Thwaites Glacier. You can see the difference in the amount of cover on the western side of both images. Lars Boehme and his team were gifted with a perfect day to look for seals on ice floes north of the eastern ice shelf, successfully tagging two of the four they found. Projects Proposed methods to study the Thwaites Glacier, labled with project acronyms/abbreviations. This section has been breaking up and retreating by about 10 kilometers since 2016.
