Atlantic Subpolar Gyre Warming – Impacts on Greenland Offshore Waters? by
Bibliographic record
Abstract
Sea surface temperature anomalies in the region of the North Atlantic Subpolar Gyre indicate cold conditions in the 1980s and warming from the mid-1990s onwards. Peak warming was observed during October 2003. This is consistent with air temperature measurements from Nuuk/Greenland which document that 2003 was the warmest year since 1950. The sub-surface ocean hydrographic properties off West Greenland follow the observed warming of the Subpolar Gyre, and show a significant upward trend which is considerably higher than the mean warming trend as documented for the North Atlantic basin. Warming of the West Greenland Current amounted to 0.096°C/year during 1983-2004. Long-term observations from Fyllas Bank/West Greenland (1964-2004) reveal that during the 1960s similar warm sub-surface conditions were present in the West Greenland Current system, however the recent years of the new century indicate record warming which exceeds the autumn observations during those times. Data from a newly formed oceanographic section across Davis Strait and the West Greenland shelf, show increased transport of the West Greenland Current through the 330m km wide passage between Holsteinsborg/West Greenland and Baffin Island/Canada. Ocean properties during 2004 were more saline and up to 2K warmer-than-normal during autumn. Volume transports across this passage, computed for the 2004 data and compared to historic Canadian data, reveal that the transports based on the geostrophic method alone are + 2.4 Sverdrup (1 Sv =

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.
