Core coring in Antarctica

In order to study the Earth’s glaciers, cores are drilled to take samples of ice in the form of a long cylinder shaped ice-cores (ice coring). Thanks to the EPICA project (European Project for Ice Coring in Antarctica), two ice cores have been made, one at the Italian-French Station in Concordia, where a depth of 3,270 m was reached, the other at the German Station in Kohnen, where the bedrock was reached at a depth of 2,774 m. For many years the longest documentation regarding the composition of the atmosphere of the past was given by the core extracted at the Russian Station in Vostok (Antarctica) which covers a period of time of 420,000 years. With the extraction carried out with the EPICA project the explored period of time has been doubled, compared to previous knowledge (820 thousand years).
