A research team of 12 European scientific institutions has begun the fourth and decisive drilling campaign of the Beyond EPICA - Oldest Ice project at the Little Dome C field, located 35 kilometers from the French-Italian Concordia Station in Antarctica. This international effort, led by the National Research Council's Institute of Polar Sciences (CNR-ISP), aims to continue drilling from the depth reached last season, 1,836 meters, to 2,750 meters, where rock substrate is expected to be found. At this depth, the ice could contain records of Earth's climate history dating back 1.5 million years, revealing for the first time direct information about atmospheric temperature and greenhouse gas concentrations. The team, consisting of 16 scientists and logistical staff, will work for two months in Antarctic summer conditions, with average temperatures of -35°C, at the remote Little Dome C field, at an altitude of 3,200 meters above sea level. After reopening operations at the field, the team began drilling activities a few days ago, already reaching a depth of more than 1,900 meters.
