Glacial landforms and preliminary chronology of ice-movement in the Arrowsmith River map area, Nunavut
Bibliographic record
Abstract
Preliminary investigation of ice-flow directions in the Arrowsmith River map area in the Committee Bay area of Nunavut, indicates that ice moved in four directions: initially toward north-northwest, then to the north, then towards the northeast, and then north-northeast. It is uncertain whether these shifts in direction indicate discrete ice advances and retreats or directional shifts of the same advance. Moraine segments, striae, roches moutonnées, and crescentic gouges provide evidence of paleo-ice-flow direction. Prominent features such as eskers and Nye channels with cataracts and plunge pools indicate meltwater drainage to the north. Other features such as proglacial lakes, raised shorelines, and large imbricated channel boulders suggest that the area experienced high water levels and associated high meltwater discharges during ice disintegration. Till and esker samples are being analyzed for grain size, stone provenance, and heavy minerals to determine potential ore dispersal (if any) since ice flow was across Archean greenstone belts.

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.
