How large were the temperature fluctuations in Greenland over the last 70'000 years? New insights from stable isotope ratio measurements on polar ice cores with a novel on-line extraction technique
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 (...

| Summary: | 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. |
