Secrets of the Ice – Australian Antarctic Program
Since the 1950s, ice cores have been drilled from the Greenland and Antarctic ice sheets and glaciated areas around the world. The current longest continuous ice core record extracted from Antarctica, at Dome C (about 1200 km from Australia’s Casey station), extends back 800,000 years (the EPICA ice core).. By studying these cores scientists have been able to reconstruct past temperatures ...
