Flux of methane release and carbon dioxide sequestration at Winterhouse Canyon, Gros Morne, Newfoundland, Canada: a site of continental serpentinization
Bibliographic record
Abstract
We measured CO2, CH4, and N2O gas fluxes from a pool of ultra-basic water discharging from serpentinized rock in Winterhouse Canyon, Gros Morne, Newfoundland. The flux of CH4 released and CO2 sequestered were calculated to be 4.6 × 10−7 and 1.9 × 10−5 mol/(m2·min), respectively, whereas N2O concentrations showed little change. The net radiative forcing owing to the changing concentrations of CO2 and CH4 during the sampling period was –0.21, suggesting that the ultra-basic pool in Winterhouse Canyon has a net cooling effect on the atmosphere. Similarly, the net global warming potential over a time horizon of 100 years was –7, also suggesting a small cooling of the atmosphere. Overall this study was the first to consider the impact of CO2 sequestration and CH4 emissions from an ultra-basic pool above serpentinized rock and demonstrated the need for more research on the net global impacts of serpentinization.

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.
