AbstractPermafrost geochemistry: Our limited understanding of process-based geochemistry within permafrost terrains represents a substantial knowledge gap that undermines environmental risk assessment in Canada's permafrost terrains. This activity aims to address this knowledge gap.
Environmental Risk: Building of the Inuvik to TuktoyaktukHighway (ITH) from 2014-2017 has generated solute release that represents an environmental risk. This proposal aims to determine the environmental geochemistry (i.e. source, transport mechanisms, receiving environment) of this solute release and thus generate knowledge to help quantify this specific environmental risk, and in general build knowledge of the environmental risks of infrastructure development within permafrost terrains.
Seasonal Hydrology: The role of hydrology, and particularly the seasonality of groundwater hydrology, in solute mobilisation, movement and fixation is virtually unknown for permafrost terrains. Active hydrological cycle processes will be investigated in this project to determine their relationship to process geochemistry.
Summary(Plain Language Summary, not published)
This presentation was an introduction about the research that will be undertaken over the next 5 years under the Environmental Geoscience Program. The goal is to distinguish the environmental effects of natural resources development of those from natural processes. This new phase of research will be looking at marine spills, Canada's largest watershed, permafrost geochemistry, volcanic mercury contribution, mining impacted watersheds, assessments of aquifers, diluted bitumen and permafrost degradation.
