Abstract
Determining the conditions under which an approaching ice floe becomes entrained under an intact ice cover is a fundamental component of any numerical model that attempts to successfully predict ice-jam formation or ice-jam release events. Current stability theory is based on empirical relationships that attempt to characterize stability on the basis of Froude number. This paper seeks to evaluate the stability of floating ice blocks though a force-moment analysis, building on previously published experimental results that measured the dynamic pressures beneath a floating ice block under various thickness-to-depth ratios and flow velocities. The experimental results were extended to measure the dynamic pressures beneath a block that had rotated about its downstream corner until the top upstream corner was at the water surface elevation, giving an indication of how the submerging force and underturning moment changes as the block begins to rotate. The force-moment analyses developed in this paper were compared with previously published observations of block entrainment and were found to match those observations well.

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 it
