Impacts of wildfire on the permafrost in the boreal forests of Interior Alaska
[1] The impact to the permafrost during and after wildfire was studied using 11 boreal forest fire sites including two controlled burns. Heat transfer by conduction to the permafrost was not significant during fire. Immediately following fire, ground thermal conductivity may increase 10-fold and the surface albedo can decrease by 50% depending on the extent of burning of the surficial organic s...

15 صفحه اولCumulative impacts on Alaskan arctic tundra of a quarter century of road dust1
Tundra ecosystems are sensitive to disturbance and slow to recover. To account for environmental costs of development in the North, cumulative impacts of roads and dust deposition must be quantified. After a previous study, we re-examined tundra adjacent to the 577-km-long Dalton Highway in northern Alaska to assess 13 y of additional calcareous road dust deposition. Dust loading continues to a...
متن کاملArctic tundra fires: natural variability and responses to climate change
© The Ecological Society of America www.frontiersinecology.org A surveying scientists working in the Far North for tundra-fire observations and examining Canadian Government fire records, pioneer Arctic ecologist Ross Wein concluded that “tundra fires occurred infrequently, and were invariably small in areal extent... Little is known about the ecological significance of tundra fires” (Wein 1976...
متن کاملFire effects on net radiation and energy partitioning: Contrasting responses of tundra and boreal forest ecosystems
[1] The net radiation available to drive surface-atmosphere exchange is strongly influenced by albedo and surface temperature. Tower-based microclimatic and eddy covariance measurements in typical Alaskan black spruce and tundra ecosystems before and immediately after fire indicated a 10% decrease in net radiation over the burned spruce stand but a 12% increase in net radiation over the burned ...
