Abstract

fetched live from OpenAlex

Au cours du siecle dernier, l’urbanisation, les activites industrielles et les activites agricoles ont genere une importante charge de substances toxiques qui se sont retrouvees dans les cours d’eau. Ces apports ont contribue a deteriorer la qualite de l’eau de l’immense bassin Grands Lacs–Saint-Laurent, mettant ainsi en peril la sante de cet ecosysteme unique. Les stations de reference du secteur fluvial servent a evaluer l’etat de la contamination de l’eau en enregistrant les fluctuations saisonnieres et interannuelles ainsi que les tendances a long terme des concentrations de contaminants. Depuis 1995, la region de Quebec (figure 1) sert de station de reference, puisqu’elle cumule la contamination des differentes masses d’eau qui composent le fleuve Saint-Laurent et y sont melangees sous l’effet des marees. Depuis 2003, des mesures sont egalement prises a l’ile Wolfe, a la sortie du lac Ontario (figure 1). Cette station de reference permet d’evaluer la qualite de l’eau provenant des Grands Lacs, qui est caracterisee par des eaux claires et mineralisees. En sus de ces deux stations localisees a l’entree et a l’exutoire de la partie fluviale du Saint-Laurent, une nouvelle station s’est ajoutee en 2004, pres de l’embouchure de la riviere des Outaouais, a Carillon. Les eaux de l’Outaouais, le plus important tributaire du fleuve, couvrent une large portion de la rive nord du Saint-Laurent et sont fortement colorees. Ces eaux, appelees communement eaux brunes, peuvent etre identifiees facilement jusqu’a Trois-Rivieres.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
