U8: Franklin Bluff Active-Layer Thickness in Northern Alaska

Northern Alaska active-layer thickness measurements collected under the Circumpolar Active Layer Monitoring (CALM) network. The data represent a coordinated and standardized program of observations designed to detect decadal changes in seasonal thawing and freezing dynamics in high-latitude soils. The dataset was last updated by organization SCIOPS on 2010-11-23.

Use Cases

• Modeling permafrost thaw dynamics based on active-layer thickness measurements.
• Analyzing decadal trends in seasonal soil freezing and thawing based on standardized observation protocols.
• Mapping spatial variability of active-layer thickness in the Arctic region.
• Validating remote sensing or climate models with ground-based soil thaw data.

Strengths

• Data collected under a coordinated and standardized international observation program (CALM network).
• Measurement protocols are designed specifically for detecting decadal-scale changes.
• Focus on a critical climate variable (active-layer thickness) in a key region (northern Alaska).

Limitations

• Last updated 2010-11-23 23:59:59.999000; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
