Expedition 302 - Arctic Coring Expedition

The Arctic Coring Expedition (ACEX) was the first IODP mission-specific platform operation managed by ESO (in cooperation with the Swedish Polar research Secretariat - SPRS) from August 7 to September 15, 2004. The drillsites were located on a submarine high, the Lomonosov Ridge, at a point only 250 km from the North Pole. ACEX was a huge logistical challenge because the drillship had to hold its position while surrounded by the moving ice sheets of the Arctic Ocean. This required two icebreakers, the Oden and Sovetskiy Soyuz to clear a channel through the ice to allow a third icebreaker, Vidar Viking, specially converted for the task, to undertake the drilling.
