AbstractPermafrost underlies ~50% of the Canadian landmass.
Permafrost degradation: natural release of contaminants (e.g. heavy metals), trapped greenhouse gases and saline pore fluids into the environment.
Project's objectives: 1. Assess the environmental implications of permafrost degradation; 2. Provide a baseline to better appraise the environmental consequences of resource development.
Summary(Plain Language Summary, not published)
This is the fifth year for the project leaders of the Environmental Geoscience Program (EGP) from the Geological Survey of Canada (GSC) within Natural Resources Canada to present their annual scientific updates. Twelve power point presentations illustrate all the project status of all research going on within EGP. Subjects are connected to the following key words: Volcanoes, mercury, dredge disposal at sea, oil spills, diluted bitumen, oil sands, aquifer impacts, induced seismicity, geological storage of carbon, cobalt, climate change, Mackenzie River Basin, permafrost thaw, permafrost geochemistry, and cumulative effects.
