Repeated GPR measurements of a polythermal Aldegondabreen, Svalbard revealed 20 m average thinning of this glacier during 1999-2018. Detailed GPR profiling in 2018 allows to identify and localize areas with temperate ice and to delineate an extensive zone of water inflow from the surface and trace the system of channels on most part of the glacier. Th simulated water flow paths have a good correlation with position of subglacial channels determined by GPR.
