Résumé(disponible en anglais seulement)
The permafrost region occupies approximately half of Canada's land mass. Knowledge of the distribution of permafrost and its physical properties is critical for understanding terrain stability in Arctic environments and is required information for any sort of infrastructure development (community, transportation or natural resource sector). This knowledge is becoming increasingly important as climate changes, since the distribution and characteristics of permafrost are highly correlated with climatic conditions.
The Earth Science Sector (ESS) provides Canada with multi-disciplinary permafrost expertise. Researchers at Canada Centre for Remote Sensing (CCRS) apply information and data from a range of satellites to assist in mapping and better understanding permafrost environments as well as conducting change-detection studies. Researchers at the Geological Survey of Canada (GSC) employ a variety of field-based and thermal monitoring techniques to characterize permafrost and better understand terrain processes that may result under a changing climate. Both groups utilize various numerical modelling techniques to explain observed phenomena and to predict future conditions.
This workshop on Permafrost Science was convened to highlight the various types of permafrost expertise in ESS. In addition, this workshop identified gaps and possible opportunities for new collaborative permafrost research.
