Holocene glacier chronology of the Southern Alps (New Zealand)
The Southern Alps offer excellent opportunities to investigate Holocene glacier chronologies. Reasonable numbers of studies have been carried out to date, but considerable degrees of uncertainty and significant differences between individual chronologies still persist. The final results of a recent research project on the Holocene glacier chronology in the Southern Alps utilising a multi-proxy approach of 10Be cosmogenic radionuclide and Schmidt-hammer exposure-age dating, combined with rigorous geomorphological analysis and mapping, will be presented. It will be argued that an understanding of the individual character of single glacier records and the need for climatic/glaciological spatial differentiation is essential before any compilation of a representative chronology for the entire Southern Alps should be attempted. Additionally, measures to tackle the 'geomorphological uncertainty' must inevitably become integrated in any related future approaches.
