Abstract
Strong tides on the Australian North West Shelf lead to vigorous vertical stirring and mixing. This activity near the shelf break is directly quantified with a numerical model. The model has a spatial and temporal resolution of about 800 m and 13 s respectively. The model result shows internal tides steepening as they shoal onto the slope, which is near critical for the semidiurnal tide. The main energy balance of the internal tides is between incoming internal tidal energy flux and the dissipation. The vertical and horizontal distribution of the heat flux carried by the internal tides is complex and difficult to parameterise. When area-averaged in the model region (38 km by 36 km), the vertical heat flux is in the order of –10-5 deg m s-1 (positive upward). This translates to a vertical diffusivity of 10-4 to 10-2 m2 s-1, which is an order of magnitude larger than the subgrid vertical diffusion. Both the warming and cooling rates caused by the convergence and divergence of the heat flux are in the order of 10-6 deg s-1. The neap-spring modulation of the semidiurnal tide did not significantly modify these estimates. These values can explain the vertical heat exchange inferred from large-scale analysis of the heat budget on the Shelf.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
