Anthropogenic 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...
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.

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 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 کاملFurther contributions to the aleocharine fauna of the Yukon Territory, Canada (Coleoptera, Staphylinidae)
The aleocharine beetles of the Yukon Territory, Canada are reviewed based on material studied since the most recent survey of the territory in 2008. The present contribution recognizes a fauna of 125 species, of which 9 are new to science, 20 represent new territorial records and one represents a new Canadian record. Seventeen species are considered Holarctic, 6 introduced, and 2 species are of...
متن کاملA 100-year record of North Pacific volcanism in an ice core from Eclipse Icefield, Yukon Territory, Canada
[1] A record of regionally significant volcanic eruptions in the North Pacific over the last century has been developed using a glaciochemical record from Eclipse Icefield, Yukon Territory, Canada. Tephrochronology of the Eclipse ice core provides positive identification of the 1907 Ksudach, Kamchatka, the 1912 Katmai, Alaska, the 1947 Hekla, Iceland, and the 1989 Redoubt, Alaska, eruptions. No...
