Abstract
Abstract. We use output of an eddy-permitting biogeochemical ocean general circulation model to investigate the drivers of the observed decline in the pre-bloom inventory of dissolved silicate (DSi) and its InterAnnual Variability (IAV) over the period 1980–2015. Specifically, the relative impacts of an abrupt decrease in Deep Winter Convection (DWC) and changes in Arctic inflow on DSi concentrations at the regional scale are examined. The IAV of the upper layer DSi inventory covaries with both the Arctic inflow and DWC, however, the pre-bloom decline seems driven primarily by the DWC and associated winter vertical mixing, while the contribution of Arctic inflow is negligible. Our study suggests that the inventory responds to natural decadal variability which is influenced by two major climate modes, the North Atlantic and the Arctic Oscillations, with the former appearing to be the main control.

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.
