Abstract
Results of14C/12C ratio measurements on CO2extracted from air bubbles in polar ice are presented. The samples investigated originate from the Dye 3, South Greenland, deep ice core and span approximately the last 10,000 years. The results are calibrated with tree-ring records. The14C ages are compared with information obtained from seasonal variations of ice-core parameters and rheologic model calculation.Keywords
