Deglacial chronology and glacial stratigraphy of the western Thunder Bay lowland, northwest Ontario, Canada
Bibliographic record
Abstract
northwest Ontario, indicate: i) the Rainy Lobe stood at the Brule Creek Moraine at ~10,200 14 C yrs BP fronted by glacial Lake O'Connor in the western Thunder Bay lowland; ii) the Superior Lobe advanced (the Marquette advance) westward into Lake O'Connor between ~9.9 and ~9.7 14 C yrs BP; iii) glacial Lake Kaministiquia occupied the reentrant between the Marks and Dog Lake Moraines between ~9.7 and ~9.5 14 C yrs BP; and iv) the Superior Lobe retreated from the Marks Moraine after ~9.5 14 C yrs BP, fronted by a glacial lake (glacial Lake Kakabeka).This deglacial chronology is younger than previous reconstructions and indicates the possible hydrologic connection between glacial Lake Agassiz and the Superior basin may have occurred later than expected or did not occur at all (e.g., during the Younger Drays cold period).Additionally, this constraining ice margin chronology may indicate ice remained in the Superior basin prior to the Younger Dryas and that the Marquette advance may have been a short readvance.iii

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.
