Scientists have discovered three vast canyons hidden below hundreds of feet of ice in the Antarctic. What's more, the canyons could play a crucial role in the continent's shifting future.
The findings are the first fruits of a project known as PolarGAP, which started in 2015 and was funded by the European Space Agency with the goal of better understanding the South Pole's gravity field and geography. The two-year survey used small Twin Otter planes, sensors detecting gravity and magnetism, as well as radar and laser altimeter tools. Now the results are starting to come in, published in Geophysical Research Letters.
