Interannual Variations In The Stratification And Transport Of The Labrador Current On The Newfoundland Shelf
Bibliographic record
Abstract
No abstracts are to be cited without prior reference to the author.During the past several decades’ climate conditions in the northwest Atlantic have been characterised by several extremes, from the warm 1960s and late 1990s to cold conditions of the early 1970s mid-1980s and early 1990s. The magnitude of these variations is proportional to the strength of the winter atmospheric pressure fields in the north Atlantic represented by the NAO index. Variations in stratification and the baroclinic component of the volume transport of the Labrador Current on the Newfoundland Shelf during these events are presented. The historical (1950-1999) summer temperature and salinity data along standard transects on the Newfoundland Shelf were used to compute geostrophic currents and to construct time series of baroclinic transports. The results generally show large interannual variations, but the trend indicates higher-than-average transport during the warm 1960s (low NAO index) and lower than average values during the cold early 1970s and the mid-1980s (high NAO index). During the late 1980s the transport increased to above average values that continued into the mid-1990s a period of high NAO index anomalies. The results are consistent with earlier work based on data up to the mid-1980s and with the hypothesis that increased transport of Labrador Current Water around the southeast Grand Bank during the warm 1960s on the Newfoundland Shelf resulted in colder ocean conditions further south on the Scotian Shelf. However, the higher-than-average transport during the high NAO index period of the early 1990s is not consistent with that observed during similar high NAO conditions of the early 1970s and mid-1980s.

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; a candidate call from one teacher head, not a consensus.
