Numerical modeling: A complementary tool for studying CO<sub>2</sub> emissions from hydroelectric reservoirs
Bibliographic record
Abstract
In 1993, a vast study began on the production and emission of CO 2 from hydroelectric reservoirs in central northern Québec. During the sampling field trips, information was collected about water temperature profiles, CO 2 surface atmospheric concentrations, dissolved CO 2 concentration profiles through the depth of the reservoirs, and CO 2 fluxes at the surface and the bottom of the reservoirs, as well as many surface meteorological parameters. One of the goals of the project was to develop a mathematical model capable of simulating the physical processes responsible for the vertical transport of dissolved CO 2 in hydroelectric reservoirs. This combined approach of measurements and numerical modeling confirmed certain hypotheses concerning the missing source of CO 2 , the existence of a spring peak of CO 2 emission and an intense fall peak of CO 2 emission for deep reservoirs. Moreover, a relation between differences in patterns of CO 2 emission and reservoir depth was highlighted. It is shown that the numerical model developed in this research can be used to develop sampling strategies based on the characteristics of temporal and spatial distributions associated with each reservoir.

Full frame distilled prediction
Teacher imitationNot 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.
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 teacher head, not a consensus.
