Laboratory experiments of ice scour processes: buoyant ice model
Bibliographic record
Abstract
A laboratory program was carried out to measure the loads and seabed response due to a buoyant ice block scouring a representative seabed. The results complement previous experimental data carried out at the Canadian Hydraulics Centre, which used a rigidly affixed ice block to scour seabed material representative of the Grand Banks region. The present study used the same seabed material; however in this test series, the model was towed along an ice tank, free to move throughout the water column. Seven tests were carried out. Freshwater ice, built up into a large block with an overall dimension of 0.76m x 0.76m x 0.71m, was used to scour the seabed at depths up to 0.2m. The scouring loads, displacement and angular movements and resulting trenches were measured. This report provides a description of the test arrangement and the experimental results.

How this classification was reachedexpand
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.
