Abstract
A dry extraction method was used to obtain trapped CO2 of 2-5 kg ice s amples from a blue ice zone in East Antarctica. In situ produced C-14 was also extracted in (CO2)-C-14 and (CO)-C-14 concentrations at a rat io of 3.4 +/- 0.9. Correction of trapped (CO2)-C-14 from in situ resul ted in ice dates in the range 5-15 ka. The realistic rates for accumul ation and ablation of ice indicate about total efficiency of extractio n.
