Abstract

fetched live from OpenAlex

The Mackenzie River valley is dominated by cold, dry air moving south from the high arctic in winter but receives a warm if brief summer as the arctic high pressure area retreats northward. Dry conditions are periodically modified by low-pressure cells moving from the Pacific Ocean or Beaufort Sea. Mean monthly temperatures in winter and summer tend to be uniform throughout the Mackenzie valley south of Inuvik. In winter, this is due to the parallelism between the arctic front and the Mackenzie valley as it traverses the region. In summer, longer daylight hours compensate for lower sun angles with increasing latitude to favour even heating. Snow and rainfall are low by North American standards but occasional heavy rains do occur. Throughout the 20th century, mean annual temperatures for most recording stations have on average risen between 1 and 2°C and snowdepth at the end of February has decreased.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
