14C Measurements of Ice Samples from the Juvfonne Ice Tunnel, Jotunheimen, Southern Norway—Validation of a 14C Dating Technique for Glacier Ice
Establishing precise age-depth relationships of high-alpine ice cores is essential in order to deduce conclusive paleoclimatic information from these archives. Radiocarbon dating of carbonaceous aerosol particles incorporated in such glaciers is a promising tool to gain absolute ages, especially fro...
