Studies of englacial water in Storglaciären using GPR - year two

This report describes the activities and preliminary findings of the second year of our project on Storglaciaren during the summer of 2002. Ice penetrating radar studies were used together with borehole video and other down-hole experiments to investigate englacial water flow. The radar surveys together with the borehole experiments suggest a new model for englacial drainage, wherein crevasse-like features are the main conveyors of water and form a fracturelike network consisting of numerous pathways, rather than the traditional view of a few melt-enlarged conduits in ice.
