Abstract
Abstract TOPEX/Poseidon (T/P) sea level data for the period from 1992 to 2002 are analysed to investigate sea level and current variability over the Newfoundland Slope. Sea level anomalies relative to local means for this period are derived and surface current anomalies normal to ground tracks are then calculated under the geostrophic approximation. Climatological mean surface currents normal to the ground tracks are also obtained from the solution of a regional circulation model. The sum of the model means and altimetric current anomalies is used to nominally represent absolute currents. Statistical analyses are carried out based on topographic regimes for along-slope and cross-slope current variability. The altimetric sea level and current variability increases offshore, toward the Gulf Stream or its extension the North Atlantic Current. Typical cross-track current variability is 10–20 cm/s over the southwestern (SW) and northeastern (NE) Slopes and 20–30 cm/s over the southeastern (SE) Slope. The total current variability may be estimated by a factor of 1.5 from the cross-track current variability of either the descending or ascending tracks. The sea level was higher in summer and lower in winter, with an increased range offshore. The shelf-edge current (water depth of 200–3000 m) was stronger in fall and weaker in spring. The seasonal range was up to 10–20 cm/s. Interannual sea level and current variations were also substantial. The sea level over the SW Newfoundland Slope had a fall from 1994 to 1996 and a rebound after 1997, more significant towards the deep sea, probably related to the north–south movement of the Gulf Stream. The NE Slope featured a sea level rise on the lower slope over the study period, associated with the freshening of the subpolar Northwest Atlantic. Patterns over the SE Slope appear to be in between those of the SW and NE Slopes. The Labrador Current over the slope (water depth of 200–3000 m) seemed to be strongest in 1996–1997, as a result of the equatorward traveling Labrador Current pulse.

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.
