Several researchers from the Center for Oldest Ice Exploration (Coldex) – a US mission that studies the oldest ice samples in the world – published, on December 23, the video of a camera plunging into a 93-meter-deep hole in Antarctica. , reports SkyNews.
The objective: to find the “oldest ice in the world” to better understand the evolution and future of the Earth’s climate through the study of the resistance of the Antarctic ice caps to global warming.
By analyzing the air bubbles trapped in the ice at depth, Coldex can determine the amount of carbon dioxide in the air in a given period.
In this hole drilled twenty years ago at Allan Hills in East Antarctica, scientists have so far been able to analyze 800,000-year-old fragments.
But they don’t want to stop there. They hope to “roll back [ce record] three or four million years, or even more,” said Edward Brook, climate researcher and director of Coldex at the Antarctic Sun, quoted by the British media.
