| Abstract | The Mackenzie River Basin (MRB) is one of the largest cold-water, intact boreal ecosystems in the world and has unique Earth-system's processes associated with sea ice formation, global circulation of
deep ocean currents, carbon storage, and biogeochemical cycling.The stability and integrity of the unique cryospheric, hydrologic, ecologic, and climatological processes of the MRB are threatened by cumulative impacts of climate change (the highest
degree of warming has occurred there) and natural resource development.
Is water quantity in the MRB affected by synoptic-scale climate phenomena? What could the impacts of that natural variability be combined with 21st. c climate change on
ecosystem services of the MRB? |
| 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. |
