Production, Transformation and Dissipation of Energy In Internal Tides Near The Continental Shelf Edge
Bibliographic record
Abstract
[1] In the early 1980s, in situ observations were made of the spatial-temporal variability of the density field at three separate shelf edge sites off the Canadian east coast to improve our understanding of the dynamics of the generation, transformation, and dissipation of internal wave energy through an analysis of the potential energy budget in the water column. A description of the procedure for estimating the perturbation potential energy and its principal characteristics is given within a conceptual framework, where an internal tide is generated, propagates shoreward from the shelf edge, is transformed by nonlinear effects into shorter undulations such as solitary waves and internal bores, and eventually dissipates. On the basis of observations we find that the linear approximation of the potential energy is a major fraction of available potential energy, especially in large-amplitude internal waves. The potential energy in the generated internal tide is shown to covary with the squared current volume flux in the generating region. Turbulence and mixing are expected to occur as the short, energetic waves become unstable. From the observations, the rate of energy dissipation is smallest on the Grand Bank (0.007 W m−2 over a 30 km distance). In the Scotian Gulf the loss rate is 0.05 W m−2 over a 13 km distance. At The Gully site, where the energy concentrations are the largest, dissipation is estimated to be as large as 0.2 W m−2 over a 10 km distance.

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.
