Data assimilation and horizontal structure of the barotropic diurnal tides on the Newfoundland and southern Labrador shelves
Bibliographic record
Abstract
Abstract A large set of in situ currents and elevation data, and a direct inverse data assimilation model are used in conjunction ‐with global inverse tidal solutions to obtain high‐resolution regional assimilative model solutions for the barotropic K1 and 01 tides on the southern Labrador and Newfoundland Shelves. The regional model assimilates the in situ data and a first estimate of the boundary conditions provided by the global model, so that the regional solutions draw on both regional and larger‐scale observations and dynamics. The regional assimilative solutions have r.m.s. observational misfit values of the order of 2 cm for elevation and 2 cm s−1 for currents, which are reduced (compared with non‐assimilative regional solutions) by 21% and 61% for K1 and O1 elevations respectively, and by 61% and 54% for K1 and O1 currents. A striking feature of the regional model solutions is a series of small‐scale (radius of approximately 100 km) eddy‐like features along the shelf edge. Singular value decomposition (SVD) of the assimilative elevation fields reveals the existence of topographically‐trapped waves at the shelf edge. There are amplified diurnal currents over the outer shelf and slope associated with the topographic waves, pointing to the potential for topographic amplification of other subinertial currents in the region.

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.
