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 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)
The goal of the Environmental Geoscience program (EGP) is to distinguish the environmental effects of natural resource development from those produced by natural processes, and to develop new approaches to support the sustainable use and development of Canada's natural resources through informed decision-making. The ultimate outcome of EGP is to increase the effectiveness and efficiency of Canadian environmental regulation and oversight. By developing innovative geoscience for environmental stewardship, as well as increasing public and private sector access to research findings, decision-makers have a greater capacity and are more empowered to carry out and review environmental assessments. This SP highlights the 5 public presentations provided on May 11, 2021 as well as all updates from all projects under the EGP.
