Snow and Wet Precipitation, Oil Sands Region
Assess the importance of atmospheric deposition of contaminants as a contributor to ecological impacts of oil sands development and identify sources.
• Use snowpack measurements sampled across a gridwork to develop maps of winter-time atmospheric contaminant loadings for the region ~100 km from the major upgrading facilities
• Assess long-term trends in winter-time atmospheric deposition
• Determine the potential impact of wintertime snowpack mercury loads on tributary river water mercury concentrations (Spring Freshet) using Geographic Information System and hydrological modelling approaches
• Compare snowpack loadings to those obtained from precipitation monitoring and compare spatial patterns to PAC air measurements obtained from passive sampling network
