Active Layer Thickness and Soil Temperature in Auyuittuq National Park

Auyuittuq National Park in the Canadian Arctic hosts a Circumpolar Active Layer Monitoring (CALM) grid installed in 2009. The dataset contains active layer thickness measurements from 100 points within a 100m x 100m grid, recorded annually, and soil temperature data from a nearby station with six sensors logging every two hours since 2010. It is provided by Parks Canada as part of an international climate monitoring program.

Use Cases

• Modeling active layer thickness trends based on annual probe measurements at 100 grid points
• Analyzing soil thermal regime based on sub-hourly temperature data from six sensors
• Assessing permafrost degradation impacts on tundra ecosystems based on ground stability and hydrological change monitoring
• Validating climate models with in-situ permafrost and active layer data from a high-latitude site

Strengths

• Data collection follows an established international protocol (Circumpolar Active Layer Monitoring)
• Includes high-frequency temperature measurements recorded every two hours
• Spatially detailed measurements from 100 points within a defined 1-hectare grid

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data may reflect geographic bias inherent to a single monitoring site in open_canada
