The clear facies basal ice from Alpine glaciers shows similarities with the dispersed facies of sub-polar glaciers. It results
from modifications of glacier ice close to bedrock. Its spatial distribution and physico-chemical characteristics are however poorly
known, as well as its role in glacier dynamics and interactions with the subglacial hydrochemistry. This project links field
observations (Tsanfleuron Glacier, Switzerland; Engabreen, Norway) and a mathematical model for the formation of this facies.
