A correction for in situ 14C in Antarctic ice with 14CO

We use a dry extraction method to obtain trapped C02 of shallow ice cores from a blue ice area of East Antarctica. In-situ-produced 14C extracted in 14CO2 and 10CO concentrations show a mean ratio of 3.4 ± 0.4. Correction for insitu 14CO2 resulted in ice ages within 7-13 ka. The accumulation and abl...
