Variabilité spatiale et temporelle du coefficient d'absorption de la lumière par le phytoplancton des mers arctiques canadiennes
Bibliographic record
Abstract
RÉSUMÉ: Les spectres d'absorption de la lumière par le phytoplancton ( * (443) (~( 443 )/TChl a) coefficients of the Canadian High Arctic \nwere associated to acclimation processes occurring in light- and/or nutrients-limited \nenvironments. Those limitations and high proportion of CDOM (absorbing strongly the \nultraviolet) seem to allow the growth of phytoplankton with accessory pigments absorbing \nlight at longer wavelengths. The ratio of photoprotective and photosynthetic carotenoids \n(PPC:PSC), inversely proportional to the salinity and the cell size, decreases throughout the \nCanadian High Arctic. The highest acj>*(443) values were observed in the Amundsen Gulf \nfrom May to July (i.e. spring/summer) as well as in the Hudson Bay system from \nSeptember to October (i.e. faU) , spatio-temporal regions relatively less limited by light \nand/or nutrients availability. These results will ultimately allow the accurate monitoring of \nphytoplankton biomass and productivity evolution that is likely to take place as a result of \nthe fast-changing Arctic environment.

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.
