Permafrost and surficial materials along a north-south transect: observatoins from the Norman Wells pipeline
Bibliographic record
Abstract
The Norman Wells pipeline, the first completely buried oil pipeline in permafrost in Canada, traverses 869 km of the discontinuous permafrost zone from Norman Wells, Northwest Territories to Zama, Alberta. Observations of permafrost and terrain conditions were recorded during the excavation of the 1.2 m deep pipeline trench. These records provide a unique detailed transect of near-surface permafrost extent, ice content, and sediment characteristics over terrain both newly cleared for the pipeline project as well as previously cleared right-of-ways. Frozen to unfrozen transitions average about two per kilometre, increasing to four or five transitions per kilometre in southern peatlands. Frozen ground distribution ranges from about 80% of right-of-way length at the north end to about 30% at the south end, although locally there is wide variation. Visible ice is present in essentially all permafrost encountered, averaging about 20% by volume but commonly up to 40%.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
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 teacher head, not a consensus.
