Thwaites Glacier, also known as the “doomsday” glacier, is located in the western half of Antarctica, flowing into Pine Island Bay, part of the Amundsen Sea.

With a research mission lasting for 2 months, 32 scientists quickly boarded the research ship Nathaniel B. PalmerBoaty to Thwaites on January 6. They will probe under the melting ice to better understand the extent and speed of melting that causes sea levels to rise, according to the news agency. AP.

Every year, the Thwaites Glacier disintegrates about 50 billion tons of ice, equivalent to about 45.4 billion tons of water flowing into the sea. Between the 1980s and 2017, the glacier lost 600 billion tons of ice.

The British Antarctic Survey says the glacier is responsible for 4% of global sea level rise.

The latest satellite images show that the cracks in the glacier are getting bigger and bigger, and the warming sea is causing the fracture rate to increase.

“As a global warming climate causes Thwaites to become less and less attached to the ground and increase the risk of collapse,” said ice scientist Ted Scambos of the University of Colorado from the McMurdo Antarctic research station. of America.

Before leaving, oceanographer Anna Wahlinnna at the University of Gothenburg (Sweden), shared: “This glacier is located in a very remote and difficult to reach area. It can be unstable and that makes it difficult to reach. We’re worried.”

The research team of scientist Anna Wahlin will go to the place where the Thwaites glacier is melting. Ms. Wahlin will use two research robotic ships – her own large vessel, the Ran and the unmanned Boaty McBoatface – to explore deeper beneath the Thwaites Glacier juts out into the ocean. positive.

Scientists on board will measure water temperature, seafloor and ice thickness. They will look at the cracks in the ice, how the structure of the ice is to calculate future sea levels.

Ms. Wahlin said Thwaites looks different from other ice shelves. It’s almost like a jumble of ice sheets pressed together. “So it’s becoming more and more clear that this is not a solid iceberg like other icebergs. Thwaites looks much more jagged,” Ms. Wahlin said.

According to a forecast by the US space agency (NASA), by 2100, climate change will cause sea levels to rise by 0.6 – 1.8m, mainly due to melting ice in Antarctica and Greenland. .
