Abstract
A dry extraction method was used to obtain trapped CO2 of 2-5 kg ice samples from a blue ice zone in East Antarctica. In situ produced 14C was also extracted in 14CO2 and 14CO concentrations at a ratio of 3.4 ± 0.9. Correction of trapped 14CO2 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.
