Abstract
A dry extraction method was used to obtain trapped CO, of 2-5 kg ice samples from a blue ice zone in East Antarctica. In situ
produced 14C was also extracted in 14C0, and 14C0 concentrations at a ratio of 3.4 f 0.9. Correction of trapped 14C0, from in situ
resulted in ice dates in the range 5-15 ka. The realistic rates for accumulation and ablation of ice indicate about total efficiency of
extraction.
