OZCAR-RI CRYOBSCLIM Deux Alpes - France
OZCAR-RI CRYOBSCLIM Deux Alpes
Parent Site Name
Upper part of the Deux-Alpes ski resort, Est of Grenoble in the French Alps. Area of glacially eroded gneiss bedrock, with some limestone cover remnants. Part of the area is underlain by permafrost, and the site includes one rockglacier (rockglacier Bellecombes). Many infrastructures (cable cars, dirt roads, ski tracks) partly on permafrost. One chairlift end station on the rockglacier.
General Characteristics, Purpose, History
Monitoring of permafrost on two stations: - on station 2Alpes-3065: 100 m deep borehole in bedrock, for monitoring of long term evolution of permafrost temperature - on station 2Alpes-Bellecombes: two shallow boreholes, ground surface temperature loggers and DGPS points, for monitoring of permafrost temperature and surface dynamics of the rockglacier.
The rockglacier Bellecombes was first equipped for ground surface temperature and for surface displacement monitoring in 2007. Two boreholes were drilled through the rockglacier and instrumented for continuous temperature logging in 2009. The site also serves as reference site for geophysical investigations: ERT and refraction seismic profiles were mesured in 2007, 2009 and 2012. Georadar was performed too. The borehole 2Alpes-2065 was drilled and equipped in 2010, and is operational since January 2011.
