Triple Isotopic Composition of Oxygen in Water from Ice Cores
A. Landais, R. Winkler and F. Prié
Recent analytical developments have made it possible to measure the triple isotopic composition of oxygen in water with high precision. In this note, we concentrate on the study of δ18O, d-excess and especially the added value of 17O-excess in polar ice cores for constraining the relationship between climate and water cycle organization. We present the basis for this research and the importance of the standard calibration of this new parameter not only for laboratory nter-comparison but also comparison with modeling outputs.
