Quaternary glaciomarine environments west of Committee Bay, central mainland Nunavut
Bibliographic record
Abstract
Maximum marine transgression limits are identified along the eastern and northern peripheries of the Ellice Hills map area (NTS 56 P), west-central coast of Committee Bay, Nunavut. An age estimate of 9000 to 8600 calendar (cal.) years BP is tentatively assigned to the absolute maximum marine limit (approximately 240-255 m a.s.l.) along this coastline, on the basis of marine features at comparable elevations along the northeast coast of Committee Bay. The lowest marine limit, observed 50 km inland at about 180m a.s.l., is associated with a later marine highstand. The westward-decreasing trend exhibited by the maximum marine limits is the result of relative sea-level fall during southwestward retreat of Keewatin ice. Marine fossils commonly form a shell lag atop offshore marine mud or, rarely, are in situ. Relative sea-level fall and progressive ice retreat resulted in a succession of marine communities following initial colonization by ice-proximal species such as Portlandia arctica.

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.
