The processing of the brittle ice continues in the science trench. The ice is in many pieces and the  processing team are doing a brilliant job in keeping all the pieces together in all the many cutting lines of the ice cores in the science trench. Heather is cutting the strip of for stable water isotope sampling.

At 4pm the shallow drilling the drill assembling and the processing stopped and we prepared for Saturday night. First a Gin and Tonic in Tim’s snow cave with party ice from below the finished NEEM 2010 S2 ice core followed by a ‘down under barbie’ prepared by the Australians and the New Zealanders in camp. A great Saturday night.
