Abstract

fetched live from OpenAlex

Here we examine the patterns in carbon dioxide partial pressure ( p CO 2 ) measured in a number of small boreal streams (&lt;5 km in length) in the northwestern boreal region of Québec during the ice‐free season and compare these to the patterns found in a major river (Eastmain River) and in a tributary in the same region. All systems were consistently supersaturated in CO 2 (range 450 to 5000 μ atm) streams having both higher (mean 1850 μ atm) and more variable p CO 2 than that of rivers (range 550 to 800 μ atm). Stream p CO 2 was positively related to DOC concentration and stream segment length, both suggesting a direct influence of the surrounding landscape. Calculated stream water‐air CO 2 fluxes ranged from 700 to over 3000 mg C m −2 d −1 , up to 2 orders of magnitude higher than those measured in large rivers and lakes of the same region. Small streams, despite their extremely reduced areal coverage (1% of the aquatic surface), accounted for 25% of the total aquatic C emissions, and the resulting areal stream fluxes were comparable to those measured in different soils or wetlands in the region.

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.
