Scientists camped in the Arctic are set to start drilling to save samples of ancient ice for analysis before the frozen layers melt away due to climate change, mission organisers said on Monday.
"We want to recover and preserve, for future generations of scientists, these extraordinary archives of our Planet's climate before all the information they contain is completely lost." Analysis of chemicals in deep "ice cores" provides scientists with valuable data about past environmental conditions.
"It is our responsibility as glaciologists of this generation to make sure a bit of it is preserved." There, on territory protected by the Antarctic Treaty, they will be stored under the snow at minus 50C, where no power is needed to keep them cool.
