Purpose
Aiguille du Midi is the main observing site for high mountain permafrost on rock faces in the Alps: three subhorizontal boreholes were drilled on rock faces of different aspect (NE, NW, S) and equipped with thermistor chains for rock temperature monitoring, rock sub-surface temperature is measured as well. The Aiguille du Midi is the central station of a broader observation network of rock faces dynamics, including a permanent rockfall inventory and periodic Lidar and geophysical surveys of selected rock faces. The site serves also for calibration of permafrost distribution models in rock slopes.
History
Rock surface temperature measurements started in 2005 and was completed by climatic measurements on rock faces in 2006. Three subhorizontal boreholes were drilled to 10 m depth in 2009, on various aspect, and equipped for automated rock temperature monitoring. Periodic geophysical surveys, mianly ERT, are performed since 2008. Extensometers were installed in 2012 on fractures.
