The main focus will be on analysing discharge time-series from selected hydrological stations close to glacier margins showing clear diurnal and seasonal variations related to variations in the subglacial discharge component and carry out modelling to shed light on the development of the subglacial hydraulic system. Observations of ice-velocity variations will be analysed in terms of subglacial water pressure variations obtained from the analysis. The goal of the study is to interpret these results in terms of a model for calculating variations in basal sliding from meltwater input to the basal hydrauling system. A GPS-station will be operated on the N-Hofsjökull ice cap in central Iceland as part of the study which will involve several field trips to the norther flanks of Hofsjökull.
