imageA few days ago, researchers drilled the Antarctic shelf in order to take samples of sediments on the ocean floor. Instead, they found a colony of animals that couldn't be there. About their find tells Wired.

To study the history of the continental shelf, geologist James Smith and colleagues wanted to collect sediments on the seabed beneath Antarctica. To get there, they had to melt 20 tons of snow and create 20,000 liters of hot water. This water was pumped into a pipe lowered into a well. Which gradually melted the ice and sank lower and lower. It took them 20 hours to break through a kilometer of ice in this way.
