The thickness of the cold, water free surface layer is mapped using a high frequency radar. The thickness pattern shows similarities with the pattern of the vertical velocity on Storglaciären.
Maps are presented for the subglacial topography of Storglaciären, Isfallsglaciären and Rabots glaciär in northern Sweden. The maps are results of radio-echo soundings. Isfallsglaciären consists of one isolated basin above the ice fall uhereas
storglaciären is situated in a valley which is divided into three basins. No depressions were found in Rabots glaciär. The distribution with elevation was obtained for ice thickness, bedrock and ice surface areas, and ice volumes. Data for Storglaciären: area
A plusieurs occasions on a remarqué que l'eau dans les moulins du Storglaciären était arrivée à un niveau où, s'il existe une connexion directe avec la base du glacier, la pression hydraulique aurait excédé la pression de surcharge de la glace. Si
Afin d'étudier les variations à court terme de la vélocité et du taux de contrainte dans la partie supérieure de l'aire d'ablation du Storglaciären, on a relevé la position de 20 piquets dans une grille de 375 500 m tous les 10 jours pendant les
The robustness of one-dimensional, time-dependent, ice-flow models: a case study from Storglaciären, Northern Sweden
The robustness of a simple flow-line model has been tested against new data from Storglaciären. The model appears robust for given subglacial geometry. A realistic longitudinal profile and acceptable ice surface velocities were generated. The model
has been tested in a series of sensitivity experiments, and was found to react strongly to changes in climatic parameters. Due to uneven subglacial topography underlying Storglaciären, its behavior is non-linear and prone to considerable hysteresis
. From these experiments it appears that Störglaciären was not in balance with its climate when it reached its maximum historic extent in 1915.

Studies of the net mass balance and height of equilibrium line on Storglaciären in Swedish Lapland and on Hintereisferner in the eastner Alps have shown that during certain periods the glaciers vary in phase whereas during other periods the opposite
is true. Before glaciers in different regions are compared one has to know how they are situated in relation to the major cyclonic tracks. The summer balance of Storglaciären is strongly correlated with the height of the 500 mb surface. A high 500 mb
A comparison of the mass balances and flows of Rabots glaciär and Storglaciären, kebnekaise, northern Sweden
Measurements on Rabots glaciär over the last decade give the opportunity to validate the representativity of the long mass balance record from Storglaciären for climatic studies. An excellent agreement in the trend of the net mass balance between
Simulation of particle paths and deformation of ice structures along a flow-line on Storglaciären, Sweden
This work uses a numerical model that simulates the flow to determine particle paths, transportation time and deformation of selected structures in Storglaciären. This model suggests that blue-ice structures observed on the ice did not originate
The excavation of the Storglaciären trough during the Quaternary
The results from several years of monitoring the suspended-sediment transport in the proglacial Tarfalajåkk Creek are used to calculate the time necessary for the creation of the Storglaciären glacial trough in the Kennekaise massif, northern Sweden.
Effect of uncertainties in measured variables on the calculated mass balance of Storglaciären
Detailed mass balance measurements have been carried out on Storglaciären since 1945, adhering to a fixed system of measurements since the 1960s. Using a geographical information system approach, the effect of parameters such as density conversion
model, systematic snow probing error and ablation gradient calculation on the mass balance of the glacier can be investigated. It is evident that the measure of total mass balance of Storglaciären is not sensitive to variations in these parameters
The surface speed of the lower one-fourth of Storglaciären increases from about 13 mm d near the terminus to slightly under 40 mm d 800 m up-glacier from the terminus. The speed reaches a maximum in late summer and early fall, and then decreases
Some aspects of energy balance and ablation of Storglaciären, northern Sweden
The purpose of this paper is to estimate the energy fluxes that drive the melt process on Storglaciären, located in the Kebnekaise massif. A case study of heat-budget calculations for a 40 day period in summer 1994 is presented. Some results from
The purpose of the programme is to study gradients in mass balance parameters across the northern Scandinavian mountains. Storglaciären is the most important glacier in the network and is measured with high accuracy and measurement density
. Storglaciären is also used as a reference for all other glaciers in the programme. In general, Swedish glaciers are still responding to the major climatic warming around 1910-1920 by retreat, and the effect of very long response times. However, measured volume
balances similar to Storsteinfjellbreen. Annual net balance was found to be similar to the Swedish Storglaciären except for 1 year (1968). Consequently, it seems clear that, all the observed glaciers in the area are showing the same general pattern
in their mass balance. Further, the more maritime Storsteinsfjellbreen does not seem to collect more snow during the winter than the more continental Storglaciären.
