The Storglaciären ( Swedish for large glacier ) is a glacier in the eastern part of the Kebnekaise massif in northern Sweden . Contrary to its name, it is - at least nationally seen - more of a small glacier, there are also much larger ones in Sweden.
The Storglaciären is a polythermal glacier . This means that inside the glacier there is both cold ice and tempered ice , i.e. ice at the pressure melting point . Most of the ice in the glacier is temperate, with cold ice only in the upper layers of the Zehr area . The average thickness of the cold ice is 35 meters, the maximum is 65 meters and is located at the southern end of the glacier.
The Storglaciären is the glacier with the longest continuous series of measurements on the mass balance . The measurements began in 1945 on the initiative of the Swedish glaciologist Hans Ahlmann and are continued to this day. The Storglaciären belongs to the so-called benchmark glaciers, i.e. glaciers for which not only glaciological data but also meteorological or hydrological data have been collected and which are regarded as representative of a region. The cumulative mass balance of the Storglaciar from 1945 to 2011 is −18.65 meters of water equivalent , which means that the thickness of the glacier has decreased by this amount on average over the entire surface of the glacier, based on the amount of water in the melted ice.
