Glacier mass balance

Detailed measurements of the mass balance - the balance between snow accumulation and ice ablation - are carried out on selected glaciers. The results provide information on the mass change (expressed as a an area-averaged value of water eqivalent) of a glacier in the observed period.

Cumulative mass change for currently investigated glaciers. These results are obtained from yearly point based mass balance measurements on the glaciers and periodical volume changes from maps or photogrammetry of the glacier surface. The long-term trends are very well recognizable. The strong mass loss in the 1940 and since the 90s in particular is remarkable. In addition, the increase in the '60s and '70s of the 20th century is notable.
