Abstract
The response of methanotrophic bacteria capable of oxidizing atmospheric CH<sub>4</sub> to climate warming is poorly understood, especially for those present in Arctic mineral cryosols. The atmospheric CH<sub>4</sub> oxidation rates were measured in microcosms incubated at 4 °C and 10 °C along a 1-m depth profile and over a range of water saturation conditions for mineral cryosols containing type I and type II methanotrophs from Axel Heiberg Island (AHI), Nunavut, Canada. The cryosols exhibited net consumption of ~2 ppmv CH<sub>4</sub> under all conditions, including during anaerobic incubations. Methane oxidation rates increased with temperature and decreased with increasing water saturation and depth, exhibiting the highest rates at 10 °C and 33% saturation at 5 cm depth (260 ± 60 pmol CH<sub>4</sub> gdw<sup>-1</sup> d<sup>-1</sup> ). Extrapolation of the CH<sub>4</sub> oxidation rates to the field yields net CH<sub>4</sub> uptake fluxes ranging from 11 to 73 μmol CH<sub>4</sub> m<sup>-2</sup> d<sup>-1</sup> , which are comparable to field measurements. Stable isotope mass balance indicates ~50% of the oxidized CH<sub>4</sub> is incorporated into the biomass regardless of temperature or saturation. Future atmospheric CH<sub>4</sub> uptake rates at AHI with increasing temperatures will be determined by the interplay of increasing CH<sub>4</sub> oxidation rates vs. water saturation and the depth to the water table during summer thaw.

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 it
