Deadhorse, Alaska is the location for this dataset of active-layer thickness measurements collected under the Circumpolar Active Layer Monitoring (CALM) network. The data represents a coordinated, standardized program using consistent protocols to observe decadal changes in seasonal thawing and freezing dynamics in high-latitude soils. The dataset was last updated by organization SCIOPS on November 23, -2010.
Use Cases
- Modeling permafrost thaw dynamics based on standardized active-layer thickness measurements.
- Detecting decadal changes in seasonal soil freezing and thawing based on coordinated observation protocols.
- Analyzing spatial patterns of active-layer thickness in a high-latitude Arctic environment.
- Calibrating or validating remote sensing or climate models with ground-truth soil data.
Strengths
- Data is part of the only coordinated, standardized global program (CALM) for observing active-layer dynamics.
- Measurements follow standard protocols designed for detecting long-term, decadal-scale changes.
- Focuses on a critical Arctic region near Deadhorse, Alaska for permafrost research.
