An examination of the spatial and temporal variability of seawater pCO2 within the Canadian Arctic Archipelago and Baffin Bay during the summer and fall seasons
Bibliographic record
Abstract
The distribution of the partial pressure of surface water CO2 (pCO2sw) was measured throughout the Canadian Arctic Archipelago and Baffin Bay during the summer and fall. Throughout these two seasons, values ranged from 110 μatm and 436 μatm, demonstrating the high level of variability in pCO2sw across the archipelago. Surface waters remained undersaturated compared to atmospheric pCO2 (~386 μatm) for the majority of the sampling period. Generally, areas in which remnant sea ice was melting were observed to be the most undersaturated, whereas warm, ice-free waters in proximity to rivers were supersaturated with respect to atmospheric pCO2. These observations demonstrate how the influence of freshwater from sea ice melt and rivers affect pCO2sw differently. The region was found to act as an overall sink, absorbing on average 17.6 mmol CO2 m-2 day-1 throughout the two seasons. Seasonally specific factors controlling pCO2sw and their effects through a warming climate are discussed.

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.
