Bibliographic record
Abstract
Abstract. The first (and second) baroclinic deformation (or Rossby) radii are presented north of ∼ 60 ◦ N, focusing on deep basins and shelf seas in the high Arctic Ocean, the Nordic seas, Baffin Bay, Hudson Bay and the Canadian Arc-tic Archipelago, derived from climatological ocean data. In the high Arctic Ocean, the first Rossby radius increases from ∼ 5 km in the Nansen Basin to ∼ 15 km in the central Cana-dian Basin. In the shelf seas and elsewhere, values are low (1–7 km), reflecting weak density stratification, shallow wa-ter, or both. Seasonality strongly impacts the Rossby radius only in shallow seas, where winter homogenization of the water column can reduce it to below 1 km. Greater detail is seen in the output from an ice–ocean general circulation model, of higher resolution than the climatology. To assess the impact of secular variability, 10 years (2003–2012) of hydrographic stations along 150◦W in the Beaufort Gyre are also analysed. The first-mode Rossby radius increases over this period by ∼ 20 %. Finally, we review the observed scales of Arctic Ocean eddies. 1

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.
