Ice cores offer unique archives of multiple indicators of past glaciological, climatic and environmental changes. Measurements conducted in borehole and ice cores can provide crucial information regarding the dynamics of polar ice sheets and put constraints on their past extension. The wealth of geochemical analyses which can be performed on ice cores make it possible to reconstruct past variations locally, but also regionally (at the location of moisture and aerosol sources) and globally (well mixed greenhouse gases), as well as to document key climatic forcings linked with natural and anthropogenic aerosols and with solar activity. This symposium will be dedicated to the paleoclimatic information derived from ice cores. This includes results from new ice cores drilled in various latitudes and documenting climate variability over various time scales.
We also welcome presentations of innovative methods in order to broaden the spectrum of glaciological, climatic and environmental parameters derived from ice cores; these methods may be linked with analytical innovation, or may rely on new modelling approaches in order to improve the physical understanding of the deposition and archiving processes. We especially encourage contributions about meteorological aspects of ice core interpretation, such as precipitation origin, moisture transport to the drilling locations, general atmospheric circulation in past and present climates, moist deposition of chemical components, etc. Finally, this session will be also open for the comparison between ice core records with other paleoclimatic archives such as marine sediment or speleothem records, and for the comparison between glaciological and climatic models and ice core results.
