Annual variation of the Frost Table at Kangerlussuaq airport
Anglès: Permafrost has become the most important feature in civil engineering in all the arctic regions. The construction of a new structure, such and road or and airfield, changes the thermal regime of the ground leading to a faster degradation of the frost table. The heat caused by the new structu...
