Over het archief
Het OWA, het open archief van het Waterbouwkundig Laboratorium heeft tot doel alle vrij toegankelijke onderzoeksresultaten van dit instituut in digitale vorm aan te bieden. Op die manier wil het de zichtbaarheid, verspreiding en gebruik van deze onderzoeksresultaten, alsook de wetenschappelijke communicatie maximaal bevorderen.
Dit archief wordt uitgebouwd en beheerd volgens de principes van de Open Access Movement, en het daaruit ontstane Open Archives Initiative.

| Abstract |
This work analyses on the factors involved in apparent isotopic fractionation during water/ice phase changes. Stable isotopes of oxygen and hydrogen have been considered. A combined approach is an originality of this research. Models and computer simulations are used to predict the isotopic distribution in ice formed by water freezing in various environmental settings. Development of a box diffusion model combined with the boundary layer concept leads to a possibility of determining freezing rates from the isotopic composition of the ice. The model is tested experimentally and the method successfully used in the interpretation of field results. Implications on antarctic glacio- logy are outlined. |
