Scientists Archive Alpine Ice Samples in Antarctic Sanctuary

A section of the Mont Blanc glacier has become one of the first Alpine ice samples stored in a unique Antarctic archive designed for future scientific research. On 14 January 2024, ice from Mont Blanc in France and the Grand Combin glacier in Switzerland were placed in the Ice Memory Sanctuary. This facility, situated near the Franco-Italian Concordia research base on the Antarctic plateau, aims to preserve vital climate data as glaciers around the world continue to melt at alarming rates.

The initial two ice cores, transported in -20°C containers, will remain nine metres below the surface of the Ice Memory Sanctuary. This location is expected to serve as a crucial archive for future scientists who will analyze the samples to understand historical climate patterns and human impact on the environment. Over the coming years, ice from glaciers in regions including Bolivia and Tajikistan will join these initial samples in the Antarctic vault.

According to Professor Carlo Barbante, Vice Chair of the Ice Memory Foundation, the preservation of these samples is essential. He states, “The ice doesn’t lie. All the samples are different—the ice cores from non-polar regions tell us the history of the regional climate they are from.” This initiative seeks to enable future researchers to employ advanced techniques to study various environmental indicators preserved within the ice, such as atmospheric changes and traces of human activity.

The urgency of this project is underscored by current projections regarding glacier loss in the Alps. Professor Barbante notes that glaciers below 4,000 metres in elevation are expected to vanish before the century’s end. He emphasizes that even those glaciers that manage to survive will face significant degradation due to ongoing climate change.

The opening ceremony of the Ice Memory Sanctuary was marked by a sense of hope and solemnity. Celeste Saulo, Director General of the World Meteorological Organization, remarked on the rapid disappearance of glaciers, stating that since 1975, they have lost an area equivalent to a block of ice the size of Germany, with a thickness of 25 metres. “Information lost can never be recovered,” she cautioned.

The event also included reflections from Professor Jérôme Chappellaz, the project’s founder, who expressed a mix of pride and concern about the global response to climate change. He articulated the project’s significance, saying it represents both a scientific achievement and a sobering acknowledgment of the threats facing our planet’s cryosphere.

Honourary President of the Ice Memory Foundation, Prince Albert II of Monaco, also attended the ceremony. He echoed the sentiments of the scientists, stressing the importance of recognizing glaciers as a common heritage. “The memory of our planet matters. Safeguarding it is our common duty and responsibility,” he stated.

Despite the promising design of the Ice Memory Sanctuary, which can remain structurally sound for decades, it faces ongoing challenges. The Concordia research team is confident in the integrity of the ice caverns but acknowledges the need for continued diplomatic and political support from both France and Italy. The project is safeguarded under the 1959 Antarctic Treaty and the Madrid Protocol, yet it requires a commitment to its legal protection to ensure its long-term viability.

This initiative exemplifies a proactive approach to climate science, emphasizing the urgency of preserving Earth’s cryosphere for future generations. The Ice Memory Sanctuary not only aims to protect valuable scientific information but also serves as a reminder of the fragility of our planet in the face of climate change.
