Abstract
A physical model study investigated alternatives to improve ice passage at the Soo Locks in Sault Ste. Marie, Michigan. This paper describes the ice problems at the Soo Locks and the solutions developed in the study. Model tests were conducted to evaluate the performance of high-flow air curtains to deflect ice pushed ahead of vessels entering the 366-m-long Poe Lock. A series of air curtains and an array of point source bubblers were also tested to break ice jams in the upper approach of the adjacent MacArthur Lock. In addition, an array of high-flow point source bubblers was developed in the model to relieve ice congestion in front of the downstream miter gates of the Poe Lock. A model water cannon was also found effective for clearing ice in front of miter gates and breaking jams in the upper lock approach.Key words: Soo Locks, physical model study, ice passage, winter navigation, Great Lakes, high-flow air curtain, point source bubbler, miter gate, water cannon.

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.
