Abstract:

We present the new reference chronology (AICC2023) providing an age vs depth relationship covering the last 800 kyr (thousands of years) for five ice cores (EDC, EDML, NGRIP, TALDICE and Vostok). To construct the new AICC2023 chronology, we used new highly resolved measurements for EDC ice core as well as novel absolute 81Kr ages, stratigraphic links between the five ice cores and accurate firn modeling estimates. The new chronological and glaciological information were combined in the Bayesian dating tool Paleochrono to obtain the AICC2023 timescale.
