Researchers Discovered 1.2 Million-Year-Old Ice in the Depths of Antarctica, Providing a Unique Insight into Earth’s Ancient Climate and Giving Critical Clues to Understand Climate Changes Throughout the Planet’s History

Scientists from the Beyond EPICA – Oldest Ice project achieved an extraordinary feat by drilling 2,800 meters into the ice of Antarctica, obtaining a core that records Earth’s climate from up to 1.2 million years ago.

This unprecedented discovery was made at Little Dome C, a remote area on the frozen continent. This significantly advances our knowledge of the planet’s climatic history.

The obtained data promises to deepen our understanding of climate changes over millions of years.

Why Are Ice Cores Valuable?

Each layer of ice in Antarctica is like a time capsule, preserving atmospheric particles, gases, and isotopic compositions from when it formed.

These samples provide clues about temperatures, carbon dioxide levels, and past climate events.

The team found up to 13,000 years compressed into just one meter of ice, creating an extremely detailed record.

“This ice core contains a high-resolution climate record dating back 1.2 million years,” explained Julien Westhoff, the chief scientist in the field and postdoc at the University of Copenhagen.

The Drilling Challenge

The work required more than 200 days of continuous effort in extreme conditions on the Antarctic plateau.

The area where the drilling took place is located 3,200 meters above sea level, with average summer temperatures of -35°C.

The location and hostile climate conditions made the project complex, both technically and logistically.

The choice of site was crucial. Cutting-edge equipment, such as radar echo sondes and advanced ice flow models, helped the team identify the ideal point for drilling.

Challenging Logistics

Transporting the samples is a critical phase of the project. The extracted ice must be kept at a temperature of -50 °C to preserve its characteristics. For this, the samples will be taken to Europe aboard the icebreaker Laura Bassi.

According to Gianluca Bianchi Fasani, head of logistics at ENEA for the project, maintaining the cold chain is an extremely challenging operation.
