Seasonal and interannual variability in runoff from the Werenskioldbreen catchment, Spitsbergen
Abstract The results from a hydrological monitoring program of Breelva basin (Spits− bergen, Svalbard) have been analysed to improve the understanding of the Werenskiöld Glacier system’s functioning in the High Arctic. Hydrographs of a 44 km 2 river basin (27 km 2 of which was covered by a glacier)...
