CAKN Permafrost Protocol: Monitoring Data for Central Alaska National Parks

Central Alaska Network of National Parks permafrost monitoring data, updated annually. The dataset includes subdirectories for locations, field notes, active layer surveys, borehole temperatures, rock glacier surveys, and soil temperature logs. Data is maintained by the Department of the Interior, with the most recent authoritative records uploaded as a zip file.

Use Cases

• Modeling permafrost thaw based on certified borehole temperature measurements.
• Analyzing active layer thickness changes over time from certified survey files.
• Monitoring rock glacier movement using certified raster data.
• Studying soil temperature trends from logger and certified measurement files.

Strengths

• Data is updated annually with a complete historical archive included.
• Includes multiple monitoring components: active layer, boreholes, rock glaciers, and soil temperatures.
• Managed by the Department of the Interior for authoritative long-term records.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data format is ZIP; internal file structures require inspection.
