Baroclinic Tide Generation at the Dolphin and Union Strait in the Southern Canadian Arctic Archipelago
Bibliographic record
Abstract
We studied baroclinic tide generation at the Dolphin and Union Strait, a channel in the southern Canadian Arctic Archipelago that consists of a shallow sill. Utilizing both observational data and numerical simulations, we found that, due to the presence of strong stratification in the summertime, baroclinic tides are generated at both M2 and K1 frequencies as a result of the interaction between the amplified tidal currents and bottom topography. The M2 baroclinic current, which is comparable to the M2 barotropic current in terms of amplitude, is dominated by linear dynamics in the first baroclinic mode. The amplitude of the M2 baroclinic current increases as the strength of stratification increases. In contrast, the K1 baroclinic current has a smaller amplitude in general. Dynamics of the K1 baroclinic current are more complicated, possibly due to nonlinear effects as well as contributions from the higher baroclinic modes. On the other hand, increasing the strength of stratification leads to a noticeable reduction of K1 elevation in the nearby basin, but has a very minor effect on M2 elevation.

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.
