| Abstract | Each Canadian national park is required to monitor and report on the state of the park. Permafrost is an integral part of the northern landscapes and ecosystems. Observations show that permafrost is
thawing in response to climate change. Northern national parks are large and expensive to access and monitor in the field. This study reports on the application of remote sensing-based spatial modelling to assess the changes of permafrost in Wapusk
National Park located in the northwest of the Hudson Bay Lowlands. Permafrost was mapped at an unprecedented high resolution of 30 m by 30 m using a process-based model. Spatial input datasets were developed based on remote sensing data and site
observations. The results show that the active-layer had a deepening trend throughout most of the park and that permafrost was degrading in areas in recent decades, especially in treed areas in southern regions. |
