Recent warming impacts in the Mackenzie Delta, Northwest Territories, and northern Yukon Territory coastal areas
Bibliographic record
Abstract
Ice wedges on northern Richards Island, Northwest Territories, and along the Yukon Territory coastlands, have responded to increased thaw depths. Observations made in 1999 are compared to those last made in these areas in 1975 and 1984, respectively. Climate data indicate that air temperatures in these areas have been warmer than average since 1978 and that warming in 1998 was an extreme event. Increased thaw in response to this warming has caused a decrease in the number of secondary and tertiary ice wedges, and is attributed to thaw truncation. Depths to the tops of ice wedges on Richards Island have increased, whereas depths have decreased on the Yukon Territory coastlands due to thaw consolidation. Thaw-tube observations indicate that 1998 thaw depths were the greatest since 1991 across the northern Mackenzie Delta region, with increases of as much as 21 cm.

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.
