Project Title

The permafrost thermo-erosion process in the continuous permafrost zone

 

Description of the project research

Water from snowmelt runoff seeping repeatedly in open contraction cracks in ice wedges can lead to the initiation of thermo-erosion gullies. Few hundred gullies have been identified in the region of glacier C-79. My research focuses on the process of thermal erosion of ice wedges, which leads to the rapid degradation of permafrost and the impact of gullies on the local drainage in wetlands. My study site is located in the valley of glacier C-79 on Bylot Island, Canada.

The objectives are to:
1) quantify the convective heat exchange between water act and permafrost;
2) characterize the geomorphology of thermo-erosion gullies from their initiation up to their stabilization;
3) determine the hydrographic changes induced by the development of thermo-erosion gullies in permafrost;
4) model the physical process of thermal erosion in different geomorphological contexts for the development of gullies.

The ubiquity of ice wedges, the sensitivity of northern ecosystems and economic development in the High Arctic makes it necessary to increase knowledge about the risks to infrastructure and the environment in connection with the gully permafrost.
