Snow cover is a characteristic feature of Arctic regions and is an important factor influencing ground temperatures. Snow is an effective ground insulator, and a decrease or compaction of snow in winter is expected to decrease ground temperatures. The purpose of this field experiment is to examine the influence of snow compaction on the properties of snow, permafrost ground thermal regimes, active layer thickness, and vegetation conditions. Undisturbed and disturbed sites in different terrain types across the treeline along the Inuvik-Tuktoyaktuk Highway corridor will be manipulated by compacting snow several times throughout the winter of 2019/2020. The compactions will be done in partnership with local industry. These manipulation experiments will help to determine whether snow compaction can effectively reduce ground temperatures and stabilize permafrost. Pending experimental outcomes, this method could be applied for use in infrastructure, such as along road sections experiencing permafrost degradation.
