Antarctica is Earth’s southernmost continent, with 98 percent of the region covered in ice measuring an average of 2km in thickness. The frozen desert, which reaches -90C at times of the year, has been of interest to NASA scientists, who use it to prepare for missions to the moon and sun. However, few have ever ventured below the ice.
It was revealed during Amazon Prime’s “Steps to the Future” how former NASA scientist Dr Jerome Chappellaz drilled below the surface to understand more about what will happen to our planet in the future.
The 2010 documentary revealed: “Researchers from the Grenoble Glaciology Laboratory have preserved precious archives taken in the Arctic and Antarctic expedition after expedition.
“The concept is very simple, the deeper we dig, the deeper we go into the past.
“The drilling tool is equipped with a knife which drills the ice and the shavings are evacuated by an endless screw.
