Description :
Bedrock temperatures were measured over a 12-month period (June 2003-July 2004) at 6 sites within the Gruve-7 coal mine in the Adventdalen valley, near Longyearbyen. Temperatures are highest in areas lying beneath the Foxfonna glacier and lowest in areas lying beneath the ice-free, periglacial upland. Episodic seepage of glacial meltwater into the mine is indicated by the presence of ice within joints and fractures in the exposed bedrock of the walls and ceilings of the mine corridor. Air ventilation seems to be affecting bedrock temperatures in the outermost, ice-free parts of the Gruve-7 mine.
