NASA An Antarctic glacier study makes "several disturbing discoveries"



According to NASA, "a few alarming discoveries" have been raised by the study of the colossal glacier Travis in Western Antarctica. At the top of the usual ice thinning story, they discovered a giant cavity – perhaps the size of the Eiffel Tower – growing at the bottom of the huge glacier.

Iceberg, roughly the size of Florida, once contained over 14 billion tons of frozen water enough to raise the world's sea level by more than 2 feet (65 centimeters). However, huge quantities of this colossal ice cube have melted in the last three years as a result of climate change, contributing to around 4% of global sea level rise.

As reported in the journal Researchers have received a clearer picture of the position of the glacier. Their findings show that Tows's glacier suffers from extensive ice, slimming and calming, as well as from a 300-meter hole in its western wing that is growing at an "explosive" pace. "[The size of] A glacier cavity plays an important role in the melting," said study leader Pietro Mililo of the NASA JPL . "Since more heat and water fall under the glacier, it melts faster."

The cavity can be seen in the center of the GIF in the dark red. NASA-led team has explored the glacier using satellites and specialized airplanes equipped with ice penetration radar to provide researchers with high-resolution data on the ever-changing shape and size of the glacier. These data shed light on another concern about the glacier's nesting line, the point at which the glacier begins to move away from the ground and sails over the sea. Studies show that the glacier Tavece has peeled off the base beneath it, which means that more than the base of the glacier is exposed to warming waters. This in turn makes the glacier even more susceptible to melting.

"We've been in suspicion for years that Tewis was not firmly connected to the base underneath," said Eric Rinyo of the University of California, Irvine and JPL of NASA. "Thanks to a new generation of satellites, we can finally see details."

Glacier Tages plays an important role in the history of rising sea levels and climate change, so there has never been a greater desire to study and understand. Only this week an icebreaker left Chile to begin a scientific expedition to the Thwaites glacier with a number of other ships, explorers, planes and marked wild seals.

"Understanding the details of melting the ocean this glacier is essential to designing its impact on sea level rise over the coming decades," added Rignot
