Glacier changes in the Bavarian Alpsfrom 1989/90 to 2006/07

摘要

The five glaciers in Bavaria which today cover a total area of less than one squarekilometer were frequently monitored by geodetic methods from the mid of the 20thcentury. In this paper, the record is extended by new surveys in 1999 and 2006. Theglaciers show a prolonged surface lowering, which is intensified compared to the1980s and reaches maximum rates from 1999-2006. Moreover, the ice thickness offour glaciers was determined in 2006 and 2007 by geophysical field techniques andallows the calculation of ice volumes. First simple extrapolations of observed volumelosses indicate that the two Berchtesgaden glaciers and Siidlicher Schneeferner coulddisappear by 2016, while the ice of Nordlicher Schneeferner endures until 2027. Icethicknesses and surface changes are visualized in five annexed maps.
