Parks Canada provides active layer thickness measurements from a Circumpolar Active Layer Monitoring (CALM) grid in Ukkusiksalik National Park. Measurements are taken annually at 100 points within a 100 m x 100 m grid using a metal probe to monitor climate change effects. The dataset was last updated on 2026-04-15.
Use Cases
- Model permafrost warming trends based on annual thickness measurements.
- Assess ground instability risks for tundra ecosystems based on active layer data.
- Study changes to local hydrological patterns based on soil freeze-thaw cycle monitoring.
- Analyze the impact of rising Arctic temperatures on near-surface permafrost.
Strengths
- Data is part of an international monitoring program (CALM), suggesting standardized methodology.
- Measurements are taken at 100 specific points within a defined 100 m x 100 m grid.
- Annual collection provides a time-series for tracking change.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
