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.本文呈现了针对奥地利厄茨塔尔阿尔卑斯山脉维纳特费尔纳冰川（Vernagtferner）的行为分析所用方法与研究结果。自1601年起，维纳特费尔纳的进退历程便已有记录，且相关研究的时间与空间精度持续提升。1601年至1844年的早期图像文献、1889年以来的高分辨率地图、1964年以来采用冰川学方法开展的物质平衡研究，以及1974年以来的气象水文记录与模型，以逐步提升的时间分辨率，共同揭示了该冰川三十余年来持续的冰量损失规律。
