Temporal stereophotogrammetric analysis of retrogressive thaw slumps on Herschel Island, Yukon Territory
The western Canadian Arctic is identified as an area of potentially significant global warming. Thawing permafrost, sea level rise, changing sea ice conditions and increased wave activity will result in accelerated rates of coastal erosion and thermokarst activity in areas of ice-rich permafrost. The Yukon Coastal Plain is widely recognized as one of the most ice-rich and thaw-sensitive areas i...

Our results indicate expansion in canopy cover and height of willows on Herschel Island located at 70 degrees north on the western Arctic coast of the Yukon Territory.

متن کاملAnthropogenic signals recorded in an ice core from Eclipse Icefield, Yukon Territory, Canada
Trends in the annual flux of sulfate and nitrate in a new ice core collected at an elevation of 3017 m on Eclipse Icefield, 45 km northeast of Mt. Logan were examined to determine the effect of anthropogenic activity on precipitation chemistry in the remote northwest North American midtroposphere. The annual flux of both sulfate and nitrate at Eclipse began increasing in the 1940s, demonstratin...
