On the potential to retrieve climatic and environmental information from ice core sites sufferingperiodical melt, with specific assessment of the southern Patagonia icefield. : a unique natural laboratory for environmental and climate change studies

2002 (English)In: The Patagonia Icefields: a unique natural laboratory for environmental and climate change studies / [ed] F. Sepúlveda, G. Casassa, R. Sinclair, New York: Kluwer Academic Publishers, 2002, 125-138 p.Chapter in book (Other academic)
Abstract [en]

Problems related to the preservation of atmospherically-deposited signals in an icefield are presented and their implication for a potential ice-core record is briefly discussed. The largest problems regarding ice cores from warm and wet icefields is the washout and re-deposition of the signal during percolation and refreeze of meltwater. Just how much this process alters the signal, can be assessed by making a set of diagnostics on an ice-core record. An example how this can be done is given from an Arctic icefield. Finally the potential to retrieve a good ice-core record from the Southern Patagonia Icefield is discussed. Based on earlier work it seems likely that a good record can be retrieved on the highest and driest areas of the icefield.

Abstract [en]

The volume is the proceedings of a meeting held on board a Chilean Navy ship, which sailed along the fjords, where the participants had the opportunity of actually setting foot on the Southern Patagonia Icefield.The volume presents an updated review of glacier and climate-related research of the Patagonian icefields, and will become necessary reading for anyone interested in the Patagonian glaciers and the surrounding environment.

This book presents a collection of 17 papers by authors from eight different countries from diverse fields dealing with multi disciplinary research on the Patagonian Icefields. The main emphasis is glaciology, climatology and paleoclimatology, with contributions in glacier ecology, microbiology and aerosols.
