World’s first ice archive created to preserve fast-melting glaciers’ secrets

Scientists have developed the world’s first ice archive in Antarctica, aiming to protect the records related to rapidly melting glaciers and secrets of Earth’s past climate for centuries to come.

The researchers moved two ice samples collected from Europe’s Alps and moved them to a newly-created “snow cave” in Antarctica. This cave is designed to serve as a global archive to save significant samples for the future.

The ice sanctuary is located at the high altitude Concordia station along with a natural temperature of -52°C (-61.6°F). This temperature would allow the samples to preserve forever without using any artificial means.

The underground cave is 35 metres long and five metres high and wide, sitting 10 meters beneath the surface where temperatures stay constant all year round.

According to Thomas Stocker, a Swiss climate scientist and chair of the Ice Memory Foundation, which spearheaded the initiative, "To safeguard what would be otherwise irreversibly lost... is an endeavour for humanity.”

This revolutionary project took almost ten years to finish as throughout the making it was ridden with both diplomatic and logistical challenges.

According to scientists, in the decades to come they are hoping to fill the cave with ice samples taken from the Andes, Himalayas and Tajikistan.

Unlocking secrets of climate science

This recent push to preserve the records stems from the Ice cores’ abilities to hold the secrets of climate of millennia past, helping the researchers to unravel the mysteries long after the retreat of these glaciers in the wake of global warming.

According to Carlo Barbante, an Italian climate scientist and vice-chair of the Ice Memory Foundation, "Scientists will use technologies that we cannot even imagine today, and they will extract secrets from the ice that are currently invisible to us.”

What does this ice sanctuary means at global level

On Wednesday, European and US climate experts confirmed that 2025 was the third hottest year on record. Given the intensity and frequency of global warming, this archive would prove fruitful in saving the heritage before it will vanish.

The sanctuary is hosted at the French-Italian research station on land governed by a global treaty.

The foundation's director Anne-Catherine Ohlmann told AFP, “It was important that this heritage is governed so these ice cores will be available in a few decades, perhaps even a few centuries, for the right beneficiaries for the right reasons for humanity.”
