A Correction for In-Situ 14 C in Antarctic Ice with 14 CO
We use a dry extraction method to obtain trapped CO 2 of shallow ice cores from a blue ice area of East Antarctica. In - situ -produced 14 C extracted in 14 CO 2 and 14 CO concentrations show a mean ratio of 3.4 ± 0.4. Correction for in - situ 14 CO 2 resulted in ice ages within 7–13 ka. The accumul...
