During the 2002/03 season, the drilling at Dome C reached a depth of 3,200 meters. The preliminary dating shows that the ice is about 900,000 years old at this depth – the oldest ice core ever.

The 2003/04 season was devoted to maintenance, but during the 2004/05 season researchers drilled the remaining 100 meters.

The drilling at Kohnen Station in Dronning Maud Land continued this season. The goal was to reach bedrock at 2,750 meters.

There were no Swedish participants at any of the stations this season.
