Abstract
Abstract. A northward shift in the Gulf Stream (GS) path is considered a fingerprint of a weakening Atlantic Meridional Overturning Circulation (AMOC) and has been linked to recent ecosystem alterations in the northwest Atlantic Ocean. Temperature-based criteria, widely used as proxies for GS location, suggest a northward shift. This study uses high-resolution climate models to show that these criteria, especially those based on the North Wall, overestimate the shift under high-emission scenarios by a factor of two to three. In contrast, a sea surface height (SSH)-based criterion remains more closely aligned with the true GS path, providing a more reliable estimate. The rising seawater temperature biases isotherm-based assessments, creating a misleading indication of a GS migration. These results call into question the notion that warming in the northwest North Atlantic is causally related to a northward migration of the GS and emphasize the need for more robust indicators of its position.

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.
