| Comment |
Permafrost aggradation may be caused by climatic cooling or by changes in terrain conditions, including vegetation succession, infilling of lake basins and a decrease in snowcover. It can also occur under ice arenas, road and airfield embankments, etc. It may be expressed as a thinning of the active layer and a thickening of the permafrost, as well as an increase in the areal extent of permafrost.
