Current broadening as a mechanism for anticyclogenesis at the Northwest Corner of the North Atlantic Current
Bibliographic record
Abstract
The warm North Atlantic Current, flowing north just east of the Grand Banks, makes an abrupt turn to the east near 51°N. As the waters flow through this region, known as the Northwest Corner, the current broadens and weakens, effectively splitting into two zonal yet variable flows forming what is generally known as the Subpolar Front. The Northwest Corner also has the curious property that it expands and expels anticyclonic vortices on a quasi‐regular basis, approximately every 2‐1/2 months. Using an energy budget approach we show that this anticyclogenesis can be accounted for in terms of a kinetic energy convergence due to the broadening of the flow as it passes through the region. The principal export route for the newly formed eddies appears to be density‐driven subduction, i.e. sinking, driven by severe heat‐loss due to the exposed position of these warm waters in the southern Labrador Sea.

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.
