Northern Ecosystem Change: Burning & Thawing
Each summer as air temperatures rise amongst the midnight sun, permafrost begins to thaw top down. This thawing is short lived though as fall’s cool breath begins to show itself in late August and these soils refreeze as the long winter sets in. Understanding what controls the depth of this top do...
