Scientists complete a major research expedition in East Antarctica

Scientists have officially concluded the 'COOKIES' expedition, a landmark 55-day research mission in East Antarctica.

By analyzing ocean layers, biological samples like eDNA, and sediment cores acting as 'time capsules', researchers are piecing together how Antarctica responded to past warming.

Despite battling sub-zero snowstorms and massive icebergs, the team successfully gathered data that will help predict future climate trajectories.

This mission also marked a significant operational milestone: the RV Investigator has now spent a cumulative year at sea dedicated to Antarctic science.
