Permafrost Temperature Data from Arctic Alaska Borehole Array

Permafrost temperature data originates from a 24-borehole array in Arctic Alaska, managed by the U.S. Geological Survey as part of the Global Terrestrial Network for Permafrost. The dataset contains fully processed temperature measurements from borehole logs, representing true temperatures in wellbores and surrounding rock. Data collection spans from 1973 to 2014.

Use Cases

• Analyzing long-term permafrost temperature trends over a 41-year period.
• Validating and calibrating thermal models of subsurface Arctic environments.
• Assessing the thermal state and potential thaw of permafrost based on direct borehole measurements.
• Supporting studies on climate change impacts on Arctic infrastructure and ecosystems.

Strengths

• Data covers a long temporal range of 41 years (1973-2014).
• Measurements are from a structured 24-element borehole array, providing spatial consistency.
• Data is fully processed, representing true temperatures at the time of measurement.

Limitations

• Specific column names, row counts, and dataset size are not provided by any source.
• Sources conflict on the last updated date (2014 vs 2026), suggesting potential metadata inconsistency.
