Climate variability on the Scotian Shelf during the 1990s
Bibliographic record
Abstract
The temperature and salinity conditions of the waters on the Scotian Shelf during the 1990s are described. Three major features are highlighted. First is the presence of cold subsurface waters throughout much of the 1990s in the northeast and nearshore regions of the Shelf. The principal cause of these cold conditions, initially established in the mid-1980s, is thought to be along-shelf advection from the Gulf of St Lawrence and off southern Newfoundland with the possibility of some contribution from local in situ cooling. The second major feature was caused by the arrival in 1997-1998 of cold Labrador Slope water along the shelf break, which subsequently flooded the lower layers of the central and southwestern regions of the Scotian Shelf. While this event produced the coldest near-bottom conditions in these Shelf regions since the 1960s it was of short duration, lasting only for approximately one year. Finally, the changes in the near-surface waters of the Scotian Shelf are described. O f particular relevance were the extremely warm surface temperatures in the late 1990s and the strong vertical stratification throughout the decade. The latter was a result of record low salinities in the near-surface waters that appear to be advected onto the Shelf from off the G rand Banks. The impact of these changes in ocean climate on some of the Shelf fish stocks is briefly discussed.Description not yet available.

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.
