Ice core research, Antarctica
Ice core research. Microscope view of an ice core drilled from deep down inside the Antarctic ice cap. This ice core was obtained from a depth of over 3 kilometres, dating to around 900,000 years ago. Analysis of this and other ice cores can reveal changes in climate during this time, and air trapped in the ice core provides evidence of what the composition of the atmosphere was when the snow fell. Such studies can help understanding of past, present and future climate change. This ice core is from the Dome C site, 3233 metres high on the East Antarctic plateau. It was obtained as part of the European EPICA project (2001-5). This core was obtained in 2005, when EPICA was reaching its deepest depths.
