The impacts of climate change and global warming increase the pressure on the environment. This is especially visible in the Arctic and Antarctic and, as such, new ways of tracking the evolution of the polar ice caps are required.
A better understanding of the dynamics of the ice caps and the snow cover of the two polar regions is important for environmental (climate) as well as economic and political (territorial sovereignty) reasons.
The goal of the project, which is being carried out jointly by French researchers Michel Fily and Ghislain Picard from the Laboratoire de Glaciologie et Géophysique de l'Environnement in Grenoble, and Québec researcher Alain Royer from the Centre for Research and Applications in Remote Sensing (CARTEL) of Université de Sherbrooke, is to conduct new on-site observations. These will make it possible to develop innovative analytical methods (satellite remote sensing) to keep track of climate change indicators by satellite in the polar and Subarctic regions.
The researchers hope to be able to better understand changes in the dynamics of the ice and find out more about the timing of the snowmelt in three different polar environments distinguished by their climate regime and type of snow: Dome C (Concordia Station) in the Antarctic, the Arctic continental shelf (Barnes Ice Cap) and the Arctic and Subarctic tundra (Northern Québec).
These studies will make it possible to:
