Accelerator mass spectrometry and ice core research

AMS has opened up the possibility of measuring 10Be and 36Cl on samples of 1 kg of ice and 14C on CO2 extracted from 10 kg of ice. The 10Be data of Greenland ice cores show fluctuations which are correlated with the short-term (200 yr) 14C variations observed in tree-rings. Also major climatic chang...
