International audience Polar ice in Antarctica and Greenland is a primary archive to reconstruct Quaternary climate. An accurate chronology is necessary to exploit this archive. Dating methods can be derived from the counting of annual layers, from radioactive methods, from the comparison to other archives or from the modelling of the glacial sedimentation process. These methods being complementary, probabilistic models have been developed to combine them in an optimal way.
