Seasonal contribution of CO<sub>2</sub>fluxes in the annual C budget of a northern bog
Bibliographic record
Abstract
Peatlands are sinks for carbon dioxide (CO 2 ) because net primary production exceeds decomposition. The contribution of non‐growing‐season fluxes to the annual C budget of a peatland is, to date, little studied. We therefore measured the changes in the pattern of carbon exchange with seasons in a bog located in the cool temperate climate region. The growing season CO 2 ‐C uptake was of −113 g m −2 . During the non‐growing season, 36 g C m −2 was lost to the atmosphere, resulting in an estimated net ecosystem production of −76 g C m −2 . Despite the non‐growing‐season loss equaling 33 to 40% of the summer uptake, the net annual accumulation of was 3 times the long‐term average net accumulation rate usually cited in the literature. The high rate of non‐growing‐season efflux could be supported directly by temporal concurrent respiration and the release of stored CO 2 from prior production. These results indicate the need to revise current models to address peat thermal properties inducing CO 2 production at lower temperature ranges.

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.
