The PermaSense Consortium

Aiguille du Midi

Together with our French colleagues Philip Deline and Ludovic Ravanel of EDYTEM/Univ. Savoie we set up a wireless system to measure the crack movement on the Aiguille du Midi in Chamonix/France. For this, six crackmeters and three thermistors to measure the rock surface temperature were installed in July 2012. An online data transmission of the existing boreholes is scheduled to be installed in early 2013.

The online system is similar to the wireless sensor system running on the Matterhorn and is expected to augment the existing experimental evidence from boreholes and ERT measurements on the steep bedrock permafrost on this prominent peak.
