Title: Developing a Method for High Resolution Water Isotope Measurements in Ice Cores

Abstract: In this thesis a laser ablation system is developed for the purpose of water isotope measurements in ice. Laser ablation allows for extraction of water vapour from ice, which can then be analyzed with cavity ring down spectrometry. This work explains the advantages of this system compared to continuous flow analysis and discrete sampling. A full scale system is built and tested at the department of the Physics of Ice, Climate and Earth.
