Abstract

During the last glaciation, an ice sheet covered Iceland approximately 1000 m thick. A reconstruction of the ice flow lines shows that the ice sheet was partly drained through fast-flowing streams. The major drainage routes correlate with locations of geothermal anomalies, suggesting that ice stream activity was favoured by water produced in regions of high geothermal heat flux. A widening of active rift zone was also deduced revealing a coupling between deep and surface processes.
