Périglaciaire du Canada : idées nouvelles et perspectives globales
Bibliographic record
Abstract
Periglacial conditions which occur in Canada have been studied recently. Most of the research has been so jar limited in scope (mostly patterned ground and permafrost), undertaken for practical purposes (v.g. airport strips and the new Aklavik's site) and often carried by governmental agencies. Though a hundred titles or so of various articles and notes could be cited in a bibliographical survey of the topic, it must be underlined that the inventory of periglacial phenomena itself is still jar from being completed. This paper, prepared for the Canadian Committee of the International Commission of Periglacial Geomorphology, is based on a broad conception of the topic. The author suggests a useful series of new analytical concepts and outlines new fields for future research. The paper deals with three major aspects of periglacial studies : processes, datation and regions. Some of the processes and conditions are : terrain, wind, vegetation, the climatic « facies » (frozen ground, snow, air temperature and floating ice System). The author feels that all periglacial phenomena in Canada can be classified within a chronological sequence which he makes an attempt to establish as follows : a) Lower and Middle Wisconsin ; b) Pleniwisconsin ; c) Finiwiscon-sin ; d) Late Glacial ; and, e) Recent. Canada, in the opinion of Dr. Hamelin, can be divided into eleven periglacial « provinces ». The first jour provinces : Elizabeth, Victoria, Keewatin and Innuit are closely associated with continuous permafrost. Three provinces, Hudson, Labrador and Mackenzie, are situated in the periarctic zone. Two, Alberta and Saint-Laurent, have a southern situation along the parallel 50°N. Finally, two provinces : Yukon and Columbia, lie within the limits of Western Cordillera. These eleven provinces are proposed to serve for the designation of periglacial types or regimes throughout the cold regions of the world. The paper concludes with a glossary of new terms suggested for adoption.

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.
