Here you see a model of an ice core. On the MOSAiC Expedition, such ice cores were drilled from the Arctic ice. An ice core is obtained using an ice-coring device, which cuts a piece of ice from the depths of a glacier or ice floe. This process is similar to removing the core from an apple.
Ice cores contain crucial information about the climate’s past. Small air bubbles are trapped in the ice. The air in these bubbles can be hundreds or even thousands of years old. When scientists analyze this air, they gain knowledge about the climate of the past. Simultaneously, it helps them better understand and predict climate changes.
With these cubes, you can assemble six images captured by the Fulda-based photographer Michael Gutsche. The pictures showcase the ice landscapes of the Arctic, taken from the air, at the water’s edge, and in the deep snow. The Polarstern is also visible in the background.
