Mount Logan ice core record of tropical and solar influences on Aleutian Low variability: 5001998 A.D
Continuous, high-resolution paleoclimate records from the North Pacific region spanning the past 1500 years are rare; and the behavior of the Aleutian Low (ALow) pressure center, the dominant climatological feature in the Gulf of Alaska, remains poorly constrained. Here we present a continuous, 1500 year long, calibrated proxy record for the strength of the wintertime (December–March) ALow from...
متن کاملTemporal 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...
متن کاملExpansion of canopy-forming willows over the twentieth century on Herschel Island, Yukon Territory, Canada.
Canopy-forming shrubs are reported to be increasing at sites around the circumpolar Arctic. 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. We examined historic photographs, repeated vegetation surveys, and conducted monitoring of long-term plots and found evidence of increase...
متن کاملDiversity and Distribution of the Terrestrial Mammals of the Yukon Territory: A Review
Philip Youngman (1975) provided the most comprehensive survey of the recent mammals of the Yukon. That information was based on a survey of observations and biological collections from the late 1800s to mid-1970s, and is now over 30 years old. A recent in crease in interest in mammals, particularly non-harvested species, rare species, and species at risk, has resulted in new information and cor...
متن کاملPalaeohydrology of the Southwest Yukon Territory, Canada, based on multiproxy analyses of lake sediment cores from a depth transect
Lake-level variations at Marcella Lake, a small, hydrologically closed lake in the southwestern Yukon Territory, document changes in effective moisture since the early Holocene. Former water levels, driven by regional palaeohydrology, were reconstructed by multiproxy analyses of sediment cores from four sites spanning shallow to deep water. Marcella Lake today is thermally stratified, being pro...
