Ice-Core Records And Ozone Depletion—Potential For A Proxy Ozone Record, Paul Andrew Mayewski, Mary Jo Spencer, William Berry Lyons, Mark S. Twickler, J. Dibb

Earth Science Faculty Scholarship

Time-series of the ionic composition in polar ice cores can provide detailed direct and proxy records of seasonal to Millenial scale fluctuations in climate, atmospheric chemistry, and volcanic activity. Even though problems of species-source links and air/snow fractionation have not all been entirely resolved,the fact remains that ice cores currently hold the best hope of retrieving detailed paleo-atmospheric records. While direct links between the chemistry in ice cores and the ozone depletion phenomenon cannot be guaranteed, ice-core records provide the only means by which signals related to the ozone cycle can be produced for pre-measurement periods or for unmonitored sites. …
