Mass Balance of Axel Heiberg Island Glaciers 1960-1991

Résumé du livre

The White Glacier is a mountain valley glacier with an area of nearly 40 square kilometers and an elevation range of 53 to 1,782 meters, located on Axel Heiberg Island in the high Arctic. The mass balance of this glacier has been measured by standard techniques based on the stratigraphic system. This report describes the reassessment of the glacier's mass-balance record, which extends over 32 years. The reassessment involved detailed review of all raw data and tabulated summaries, which revealed a number of recording and processing errors. The report also discusses tests of alternative ways of estimating the mass balance, and compares the White Glacier mass balance with those of other nearby and further-afield glaciers. The next section of the report addresses the wider implications of the White Glacier mass balance, including its value as an index of climatic change. The appendix includes raw data and a report on the observational and analytical report on the White Glacier's smaller neighbor.
