This work focuses mainly on the study of rapid climate change happening during the last ice age. In this framework we developed new on-line techniques for analyses of (i) the elemental and isotopic composition of ancient atmospheric air, extracted from polar ice cores and polar firn, as well as of (ii) the stable isotopic composition of water samples taken from ice cores. The stable isotope composition of both, water and air, can be used to reconstruct ancient temperature evolution.
