A team of eight people – camp manager, two ice core drillers, five scientists – spent nearly 6 weeks at the Allan Hills blue ice area from December 2022 into early January 2023. They recovered two ice cores. One is a large-diameter (9.5”) borehole to 96 m depth at a site where 2.7 million year old ice has been previously recovered.

All three COLDEX research teams have successfully completed their 2022-2023 field seasons.

The Elephant Moraine trip was a success, recovering a 9 meter ice core at this site where previous samples taken by Korean colleagues indicate ice dating to between 400,000 and 1,000,000 years old.

All COLDEX teams send thoughts of peace and happiness to all for the holidays, and are grateful to have everyone’s support both on the ice and back home.

By Thursday December 15, drilling with the large-diameter Blue Ice Drill (BID) already reached 50 meters depth.

COLDEX projects have made steady progress this week.
