We have studied the levels of 14 C in firn and ice from two regions accumulating ice in Antarctica, Dome C, and Newall Glacier. The observed concentrations indicate variable amounts of in-situ 14 C from cosmic-ray spallation of oxygen. 14 C appears to be produced as both CO and CO 2 in variable amou...
