Abstract

This study uses a combination of evidence from ground penetrating radar, borehole, video, and wireless probe data to assess temporal changes in englacial water content associated with Briksdalsbreen, a rapidly retreating Norwegian glacier. Over a 13 day period in 2006, it is showed that ice radar-wave velocity and water content varied. It is suggested that during warm precipitation free days, void spaces within the glacier become filled with water, resulting in low radar-wave velocity. This stored water then drained during cold, high precipitation days, allowing the radar wave-velocity to rise. These changes in englacial storage were caused by the enhanced crevassing generated by the newly floating ice margin, and were associated with accelerated glacier retreat
