Interpretation of Radio Echoes from Storglaciären, Northern Sweden
Abstract Storglaciären (lat. 67.5 ° N., long. 17.5 ° E.) is a sub-polar glacier which has been the object of detailed study for many years. It responds in a sensitive way to annual and long-term changes in climate but it does not surge. Conditions at the bed and the distribution of englacial water a...
