The Arctic in Flux: How has Recent Climate Change Affected Contaminant Transport and Uptake in Aquatic Arctic Systems?
chercheur principal: Blais, Jules M
Année(s) de permis: 2013 2012
Résumé: This research will determine how the recent and dramatic climate changes in Arctic freshwater have affected the transport and fate of anthropogenic contaminants to freshwater systems, two of the largest threats facing northern communities and ecosystems. This research will develop new tools to examine how the fate of anthropogenic contaminants is affected in Arctic regions under different climate ...

EKATI Aquatic Monitoring Program, 2009-2013
chercheur principal: Wen, Marc
Année(s) de permis: 2013 2012 2011 2010 2009 2008 2007 2006 2005 2004 2003
Résumé: The main objectives of the field work for 2009 to 2013 will be to determine if the EKATI mine is having an effect on the surrounding aquatic environment and air quality, and to provide baseline data for areas where mine development may occur in the future. In winter, water samples will be collected under ice using a 5L Niskin (a cylindrical PVC water sampler). During the week of spring freshet,...

Sensitivities of high-latitude lakes to climatic & development disturbances
chercheur principal: Prowse, Terry D
Année(s) de permis: 2008 2007 2006 2005
Résumé: Climate change in the Canadian Arctic is expected to have far-reaching impacts on the hydrology and ecology of freshwater ecosystems. These systems are particularly sensitive to climate change because many cryospheric and hydrologic processes respond to relatively small in changes in climate, which in turn affect landscape biogeochemical processes and associated ecological responses. Hence, the pu...
