The new Laurentian University Permafrost course (GEOG4256) went well and was well attended, with 41 people registered in the class. Full time undergraduate students in the group were from a wide range of programs including Geography, Education, Environmental Sciences, Environmental Studies, Outdoor Adventure Leadership, Chemistry, Archeology, and Sports and Physical Education. A few mature students also joined the course, including people who have been involved in mining and reclamation work through careers in consulting, engineering, or geological techniques.
Everyone has been working hard to learn the basic principles that control ground thermal regime, ground ice formation, and how permafrost responds to changes in surface conditions. The course was interspersed with hands-on exercises, opportunities for lab work, and assignments aiming to familiarize students with basic tools for data analyses of ground thermal regimes or back of the envelope estimations of thaw and frost penetration in the ground. The equipment and facilities used were funded by Goodman School of Mines, who have been supporting efforts to develop a training program in permafrost science at Laurentian University.
Each student also worked on a research paper where s/he explored a topic linking their interests or expertise to an aspect of permafrost. This year’s paper topics included:
- the state of knowledge and common practices regarding building foundations, railway embankments, and frozen core dams in permafrost terrain;
- the evolution of different permafrost landforms (pingos, ice wedges polygons, thermokarst lakes, and retrogressive thaw slumps);
- the impacts of climatic change on permafrost, positive feedbacks, and methane emissions from thawing organics;
- the state of permafrost knowledge and research in different regions of Canada and the world;
- traditional knowledge and permafrost science;
- wildfires and permafrost;
- the impacts of frost heaving on the placement of artifact in relation to ground stratigraphy;
- permafrost in political discourse and in the media;
- risks and opportunities associated with methyl-hydrates;
- mercury methylation in permafrost environments;
- the integration of permafrost in the K-12 school curriculum.
Some of these projects, involved the use of GIS, remotely sensed imagery, or numerical modelling. Others included the development of scale models and experiments in the permafrost laboratory. Finally, some of the students from the Education program produced recommendations for the integration of permafrost-related topics in the Ontario K-12 curriculum, which will help train the next generation of Canadian permafrost scientists!
