Detailed Glaciochemical Investigations In Southern Victoria Land, Antarctica―A Proxy Climate Record, Paul Andrew Mayewski, Mark S. Twickler
Earth Science Faculty Scholarship
Advances in climate prediction depend on a knowledge of historical climatic sequences ranging in scale from decades to Millennia. Proxy data produced by pollen, sediment, tree rings,glacier fluctuations, and ice and snow cores are valuable in the construction of climatic sequences when direct observations of the atmosphere are either spatially or temporally lacking. Links between proxy data and the atmosphere generate the most confidence when actual components of climate are preserved in the proxy medium.

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

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. …
