Summary
Abstract: We have studied the levels of 14C 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 14C from cosmic-ray spallation of oxygen.
14C appears to be produced as both CO and CO2 in variable amounts, but our
results suggest rapid conversion of 14CO to 14CO2. Much of the in-situ 14C is
retained ... View entire text
