Scientists find “big variations in the temperature in the mantle across parts of Antarctica.”
“Scientists have used radar and other imaging technology to uncover some astounding finds under the East Antarctic Ice Sheet,” says this article on Live Science. “A vast mountain range that rivals the Alps, and Lake Vostok, one of Earth’s largest lakes.”
By installing a network of seismographs to map qualities of the rock deep below the surface, seismologist Doug Wiens and a team of researchers hope to figure out “what effect the Earth has on the ice sheet.”
The project is called Polenet. [See images of the scientists at work in Antarctica.]
“We do see these big variations in the temperature in the mantle across parts of Antarctica that will have a big effect on the ice sheet,” said Wiens.
