Abstract
Abstract Although temporal and spatial variations in peatland methane (CH 4 ) emissions at broad scales are often related to water table (WT) using a linear relationship, a potentially complex relationship exists between these variables locally and over shorter time scales. To explore this issue, CH 4 fluxes were measured using eddy covariance at the Mer Bleue bog over two summer seasons. Peak CH 4 emissions (30 to 50 mg CH 4 ‐C m −2 d −1 ) occurred not when the WT was closest to the surface but instead, when it dropped to 40 to 55 cm below the surface. When the WT was below or above this zone, average fluxes were ~14 mg CH 4 ‐C m −2 d −1 . We speculate this critical zone coincides with the necessary redox potentials and sources of fresh organic material that lead to maximum production of CH 4 and/or with conditions that lead to degassing of stored CH 4 . However, as expected, total summer CH 4 emissions were 47% lower during the drier year. This occurred in part because the WT was within the critical zone for fewer days in the drier year but also because after an extended midsummer dry period there was little recovery of CH 4 emissions, even a month after rewetting.

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 it
