Glacier mass balance Hallstätter Gletscher, Dachstein, Austria, 2023/2024@en

The annual glacier mass balance of Hallstätter Gletscher in Austria is measured since 1.10.2006 with the direct glaciological method in the fixed date system (1.10. to 30. 09. of the following year). The accumulation of snow is measured by determination of the water equivalent in 6 snow pits, the ice ablation is measured with 15 stakes drilled into the ice. Results are the annual net mass balance in kg, the total accumulation and ablation, the glacier area and the portions of the area which are subject to ablation and accumulation, the elevation of the equilibrium line and the specific mass balance in kg/m² (= mm w.e.). The accumulation during the winter is determined by the 1 May. The project is funded by the Federal Government of Upper Austria. The measurements are carried out the Institute for Interdisciplinary Mountain Research of the Austrian Academy of Sciences and the company Blue Sky in Gmunden, Austria.奥地利哈尔施塔特冰川（Hallstätter Gletscher）的年度冰川物质平衡观测始于2006年10月1日，采用固定日期体系（当年10月1日至次年9月30日）下的直接冰川学方法开展。研究团队通过在6个雪坑中测定雪水当量来获取积雪积累量，同时利用15根打入冰体的测杆监测冰消融量。本次观测的成果涵盖：以千克为单位的年度净物质平衡、总积累量与总消融量、冰川总面积、消融区与积累区的面积占比、平衡线海拔高度，以及以千克每平方米（即毫米水当量，mm w.e.）为单位的比物质平衡。其中，冬季积雪积累量于每年5月1日完成测定。本项目由上奥地利州联邦政府资助，观测工作由奥地利科学院跨学科山地研究所（Institute for Interdisciplinary Mountain Research of the Austrian Academy of Sciences）与位于奥地利格蒙登的Blue Sky公司共同执行。
