NRC researchers have designed and are testing a freezing system to reduce permafrost degradation in the Arctic.
- Design a system that effectively reduces permafrost degradation through inter-seasonal low temperatures redistribution
- An effective cooling device to reduce permafrost degradation by removing heat during summer months and accumulating cold during winter months
- Conduct field tests on an NRC-designed cooling method that uses a liquid-filled freezing system with a snow-deflecting cone to stabilize permafrost degradation in saturated peat in Arctic climates
- This method will provide direct and reliable cooling effects that stabilize ice rich soils, moderate surface settling and cool down advective heat transfer through active layer by groundwater
- By removing heat in summer and accumulating cold in winter, this project will help sustain frozen ground temperatures within a specific area and distribute low ground temperatures along highway embankments, building foundations or other critical localized areas, mitigating the degradation of permafrost and its impacts on infrastructure
