Three‐dimensional seasonal‐mean circulation and hydrography on the eastern Scotian Shelf
Bibliographic record
Abstract
A three‐dimensional nonlinear finite element model with an advanced turbulence scheme is used in conjunction with historical current, temperature, and salinity observations to describe seasonal‐mean circulation and hydrography on the eastern Scotian Shelf (ESS). The model solutions consist of density‐, wind‐, and boundary‐driven currents, and associated elevation, hydrographic, and turbulence fields. The M2 and K1 tides are simultaneously computed to include the effects of tidally induced turbulent mixing and bottom friction, and tidal rectification. The circulation is dominated by surface‐intensified baroclinic nearshore and shelf‐break currents, both directed southwestward with prominent seasonal and alongshelf changes. These currents are primarily associated with the equatorward inflow of relatively fresh water from the Gulf of St. Lawrence and Newfoundland Shelf/Slope. Pronounced and persistent influences of outer‐shelf banks, inner‐shelf basins, and cross‐shelf channels are evident in the circulation fields. In particular, the Sable Gully features a year‐round cyclonic partial gyre, with a net onshore flow that is greatest in spring. A relatively strong anticyclonic gyre over Sable/Western Bank contrasts a weak partial gyre over Banquereau Bank. The model solutions are in approximate agreement with observed transports and currents for the primary flow features.

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.
