Ursachen und Auswirkungen des Aussüßen im Nord Atlantik
Bibliographic record
Abstract
The main focus of this study is on the variability of the freshwater budget in the subpolar North Atlantic. This region plays a crucial role in the large scale ocean circulation since the North Atlantic Deep Water (NADW) is formed here, which is an important part of the Meridional Overturning Circulation (MOC). Repeatedly appearing freshening events in the upper layer, known as 'Great Salinity Anomalies' during the 1970s, 80s and 90s, are hereby suspected to weaken the processes of deep water formation. Besides an increase of freshwater in the upper NADW, which is mainly fed by the Deep Convection in the Labrador Sea, there is also observational evidence for a freshening of the lower NADW. In this context, a large increase of the freshwater content in the subpolar basin and in the Nordic Seas has been found in observations between 1970 and 1995. However, the mechanisms that drive this freshening are still unclear. Numerous studies have investigated the variability of freshwater exports out of the Arctic, but only little is known about the exchange with the Atlantic south of the Subpolar Gyre. This study tries to close the gap for a better understanding of the deep water formation variability and the associated changes in the Meridional Overturning Circulation (MOC).

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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; both teacher heads agree on what is shown here.
