Abstract

fetched live from OpenAlex

Abstract Mean near‐surface ground temperatures in upland terrain near Inuvik range between −4°C and −1.2°C and the thickness of permafrost is about 90 m. The warm permafrost is due to the relatively deep snow cover that accumulates in the open‐canopy forest. Changes in surface conditions may lead to permafrost degradation in this environment, as is evident from elevated ground temperatures beneath disturbed surfaces in a gravel pit, in terrain burned by forest fire and where the snow depth has been increased by fencing. The values for mean annual ground temperature near Inuvik are lower end‐members of the distribution of ground temperatures in the boreal forests of northwest Canada. The range in the mean temperature of near‐surface permafrost throughout this 1200‐km wide belt (from 0°C to about −4°C) is comparable to the range over 100 km northwards from Inuvik across the treeline (from about −4°C to −8°C).

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
