Historic Antarctic Ice Core Samples Heading to Bern

In a landmark moment for climate science, the University of Bern is preparing to receive sections of the world's oldest ice core this August. The precious samples, retrieved from the depths of Antarctica, represent a remarkable achievement in paleoclimatology, containing climate records dating back an unprecedented 1.2 million years.

The 2.8-kilometer-long ice core represents a groundbreaking scientific discovery. These samples contain trapped gases and particles that provide crucial information about Earth's climate history. The cores offer an unparalleled window into atmospheric conditions and climate patterns that existed over a million years ago, making them invaluable for understanding long-term climate change patterns and future predictions.

The journey of these precious ice cores from Antarctica to Switzerland involves careful planning and specialized equipment. Currently stored in Antarctica, the samples will be transported via an Italian research vessel equipped with special refrigerated containers to maintain their integrity. The delicate nature of these ancient ice samples requires extreme care in handling and temperature control throughout their journey.

Under the leadership of Hubertus Fischer, the University of Bern's ice laboratory has prepared extensively for this momentous research opportunity. The team will conduct detailed analysis of trapped gases, particularly CO2 and methane, to reconstruct ancient atmospheric conditions. 'This requires precision,' notes Fischer, emphasizing the meticulous nature of their approach. The university's state-of-the-art facilities and tested methodologies position them perfectly for this crucial research.

This project represents a significant international scientific collaboration, with various European universities participating in the analysis. While the University of Bern plays a central role, the distribution of ice core samples among multiple research institutions ensures comprehensive analysis and diverse scientific perspectives. This collaborative approach maximizes the scientific value of these rare samples.
