Storglaciären

Storglaciären was first documented by Svenonius who photographed the glacier in 1886 (Svenonius 1910). A few years later the glacer was mapped by the authority of Land Survey. In 1897 the front position was surveyed by Nordgren and Rönnholm for the first time using measuring tape from two marked stones. The front was photographed again in 1904 and 1907 by Borg Mesch. These early photographs show an advancing front. In August 1910 the glacier was mapped using a photogrammetric theodolite by Enquist. Enquist constructed a map in the scale 1:10 000 of the fronts of the glaciers in the Tarfala valley. In 1922 the glacier was photographed again by Odencrantz. His and Enquists photos were later used to construct a map of the Kebnekaise massif in the scale 1:50 000 (STF, 1925). Herrman made a detailed description of the front area and took photographs showing a thinning snout (Herrman, 1931). Between 1930 and 1945 the front was visited a few times in order to survey the change in front position (Mannerfelt, 1940).

Monitoring data

In May 1946 the first survey of snow accumulation was carried out (Schytt, 1947). This survey was the initiation of a long-term investigation of the mass balance of Storglaciären. Since then, detailed surveys of accumulation and ablation are carried out every year by Tarfala Research Station and the mass balance record is the longest in the world.
