Two EPICA ice cores revealing 800,000 years of climate history: an overview.
Two deep ice cores had been drilled within the European Project for Ice Coring in Antarctica (EPICA). The first core from Dome C reached a depth of 3260 m covering a time period of about 800,000 years. The second core from Dronning Maud Land (DML), drilled at Kohnen-Station, reached 2774 m depth wit...
