Glacier mass balance Vernagtferner, Ötztal Alps, Austria, 1889-2010

In this article, methods and results are presented for the analysis of the behaviour of an alpine glacier, the Vernagtferner, Oetztal Alps, Austria. Since 1601, the advances and retreats of Vernagtferner are documented and analysed with rising temporal and spa- tial precision. Early pictorial documents (from 1601 to 1844), high-resolution maps since 1889, mass balance investigations with the glaciological method since 1964 and meteorological-hydrological records and models since 1974 deliver, with increasing temporal resolution, a consistent pattern of the continual ice loss of this glacier over more than 30 years.
