Ice-core net snow accumulation and seasonal snow chemistry at a temperate-glacier site: Mount Waddington, southwest British Columbia, Canada
A 141m ice core was recovered from Combatant Col (51.3858N, 125.2588W; 3000ma.s.l.), Mount Waddington, Coast Mountains, British Columbia, Canada. Records of black carbon, dust, lead and water stable isotopes demonstrate that unambiguous seasonality is preserved throughout the core, despite summer surface snowmelt and temperate ice. High accumulation rates at the site (>4m ice eq. a) limit modif...
متن کاملAn ice-core record of net snow accumulation and seasonal snow chemistry at Mount Waddington, southwest British Columbia, Canada
A 141m-deep ice-core was retrieved from Combatant Col (51.39° N, 125.22° W, 3000m), Mount Waddington, Coast Mountains, British Columbia, Canada. Records of black carbon, dust, lead, and water stable-isotopes show that unambiguous seasonality is preserved throughout the core, despite summer surface snowmelt and temperate ice. High accumulation rates at the site (in excess of 5 m a) limit modific...
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 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...
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...
