1. 1. Possible Impact from Alaskan Forest Fires on Glaciers of St. Elias Mountains, Yukon Canada

   Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Cham Hoang; Moa Stangefelt; [2015]
   Nyckelord :Alaska; St Elias mountains; forest fires; Black Carbon; albedo; HYSPLIT;

   Sammanfattning : How great potential effect does the Black carbon emitted from the boreal forest fire region of Alaska have on the retreating glaciers of the St. Elias Mountains? In this study climate and forest fire history data of Alaska was run in the HYSPLIT wind trajectory model to generate trajectories originated from large occurring fires in Alaska from 2005 to 2014.

3. 2. Synoptic Variability of Extreme Snowfall in the St. Elias Mountains, Yukon, Canada

   Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Caroline Andin; [2015]
   Nyckelord :Snow; glaciers; Yukon; synoptic meteorology; Aleutian Low;

   Sammanfattning : Glaciers of southwestern Yukon (Canada) and southeastern Alaska (USA) are presently experiencing high rates of annual mass loss. These high melt rates have mainly been investigated with respect to regional temperature trends, but comparatively little is known about how climate variations regulate snow accumulation on these glaciers.

4. 3. Atmospheric mercury deposition in alpine snow, northern British Columbia and southwestern Yukon, Canada

   Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Pia Karlsson; [2014]
   Nyckelord :;

   Sammanfattning : High mercury (Hg) levels have been measured in fish in Kusawa Lake (KL), a subalpine, partly glacier-fed lake situated in the southwestern Yukon, Canada, but it is presently unknown where this Hg comes from. One possible source may be atmospheric deposition of Hg in snow and subsequent release by melt into the lake. LÄS MER
