Structure and mixing across an Arctic/Atlantic front in northern Baffin Bay
Bibliographic record
Abstract
A front forms in northern Baffin Bay (∼75.25°N) between Atlantic‐derived water carried by the West Greenland Current and Arctic‐derived waters exiting southward through Nares Strait and Jones Sound via the Baffin Current. Subsurface waters (e.g. below 100 m) of the West Greenland Current are as much as 2°C warmer than those of the Baffin Current. Confluence of these waters leads to a frontal transition between 100–500 m wherein cross‐frontal gradients of potential temperature (Δθ/ΔL ∼ 0.06–0.07 °C·km−1) and salinity (ΔS/ΔL ∼ 0.005–0.007 PSU·km−1) are largely density compensating (Δσθ/ΔL ∼ 0.001 km−1). Subsequent thermohaline interleaving establishes conditions conducive to mixing via cabelling and double‐diffusion. The front's location would allow it to play a contributing role in the formation of Baffin Current water structure and eventual export of freshwater to the North Atlantic.

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.
