Abstract

fetched live from OpenAlex

À plusieurs endroits, le couvert glaciel des rivages de l'estuaire du Saint-Laurent contient des débris grossiers. Un relevé des cailloux à la surface de la glace a été fait dans quatre sites. On y a mesuré plus de 300 cailloux pesant entre un kilo et une tonne. Dans les sites étudiés, les cailloux de petite taille (1 à 20 kg) prédominent avec 60 %; les cailloux de 20 à 50 kg comptent pour 25 %; les autres ont un poids supérieur à 50 kg. Dans trois des sites étudiés, la débâcle est survenue le lendemain des observations. Les cailloux à la surface de la glace ont donc été évacués au large et vers l'aval sur des distances qui ont pu atteindre 30 km avant d'être délestés. La puissance des vagues et la vélocité des courants étant relativement modestes sur les estrans du Saint-Laurent estuarien, une grande partie des sédiments grossiers excède leur compétence; les matériaux au-dessus de 10 cm sont donc exclusivement déplacés par les glaces. Le relevé des cailloux à la surface du couvert glaciel renseigne utilement sur la charge sédimentaire des glaces et aide à quantifier le processus.

Not 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.
