Bibliographic record
Abstract
Estimates of water flux and storage in organic-covered, permafrost terrains require an understanding of the factors controlling soil thaw. Field studies conducted in southern Yukon Territory, Canada, showed that ground freezing and thawing commenced at temperatures between 0.14 and 0.24C. A temperature drop below 0.6C had little effect on unfrozen moisture content. Unfrozen moisture storage shifted abruptly between a winter period value of ca. 50 mm and a summer period value of ca. 100 mm, although soil temperatures remained close to the freezing point for extended periods. The organic soil transmitted water laterally early in the thaw period while the water table still remained in the organic soil. Following this period, water movement was mainly vertical, between the ground surface and the underlying mineral sediment. The cumulative energy consumed in melting ice ðQiÞ in the active layer was ca. 76 % of the cumulative ground heat flux, and ca. 15 % of the cumulative net all-wave radiation ðQÞ measured over the snow-free ground surface. A strong linear correlation between Q and Qi, suggests that the degree of soil thaw can be estimated from Q.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
