Abstract
Please click here to download the map associated with this article. This article describes palaeoglaciological mapping of the portion of the Canadian Arctic formerly covered by the north-easternmost Laurentide Ice Sheet. The mapped area stretches between the meridians 106°W and 61°W, and the parallels 60°N and 75°N, embracing an area of 3.19 x 106 km2. The work was focused on determining the location of landforms that are required as input for a glaciological inversion model, i.e. glacial lineations, eskers, moraine ridges, ribbed moraine and De Geer moraines; and forms the basis of a reconstruction of the geometry and evolution of palaeo-ice streams in this portion of the Laurentide Ice Sheet. Emerged areas were mapped through the geomorphological interpretation of Landsat 7 Enhanced Thematic Mapper Plus (ETM+) satellite images. Information on striae and other minor indicators of glacial activity were extracted from maps and reports by the Geological Survey of Canada, published articles and, for a few locations, by the author's own observations. Information on landforms located on some submerged areas where extracted from publicly available sonar surveys. All data were digitally processed within a Geographical Information System and stored in a spatially enabled database. The results are presented as a printable map at 1:2,400,000 scale.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
