Soil water storage and active‐layer development in a sub‐alpine tundra hillslope, southern Yukon Territory, Canada

Estimates of water flux and storage in organic‐covered, permafrost terrains require an understanding of the factors controlling soil thaw. Field studies conducted in southern Yukon Territory, Canada, showed that ground freezing and thawing commenced at temperatures between −0.14 and −0.24°C. A temperature drop below −0.6°C had little effect on unfrozen moisture content. Unfrozen moisture storage shifted abruptly between a winter period value of …
