| Abstract | About one third of the global permafrost region is situated in mountainous terrain, and in Canada, large areas underlain by permafrost have mountainous topography. Although mountain topography and
terrain-related mass movements yield a much greater diversity of ground materials and temperatures per unit area than encountered in polar lowlands, the governing physical principles are the same. Permafrost in mountainous regions thereby enriches
the variety of perma-frost-related phenomena encountered beyond what is typically found in lowland areas. Permafrost thaw in mountains is relevant as it may increase the potential for geohazards such as debris flows, rock falls, rock avalanches, and
displace-ment waves. There are also implications for hydrology, water quality, and ecosystems. We argue for better integration of permafrost research in mountainous regions with mainstream permafrost research and education in Canada. |
| Summary | (Plain Language Summary, not published)
This paper summarizes the outcomes of the workshop 'Impacts of permafrost thaw in mountain areas of Canada and beyond'. The paper outlines the state of
knowledge regarding permafrost in mountainous regions in Canada and the relevance of changing permafrost conditions with respect to geohazards, infrastructure design and resource development. Research needs and recommendations to address these are
provided. The paper argues for better integration of permafrost research in mountainous regions with mainstream permafrost research and education in Canada. |
