The flow of continuous and broken ice covers through converging channels
Bibliographic record
Abstract
The present report describes work done during 2009/2010, whish is part of a project aimed at clarifying two issues: (1) the formation of landfast ice; and (2) the influence of floe size on the drift and deformation of ice covers. The flow through converging channel is used as means to examining those two issues. The present work achieved the following: (1) Established a criterion that quantifies the mobility of ice covers as they flow through constrictions. A dimensionless relationship was found which governs the level of restriction to ice flow. (2) Tensile strength of the ice cover was introduced. The results establish the feasibility of incorporating the tensile strength in the forecasts. Moreover, the role of tensile strength on the mobility of ice through restrictions was evaluated. (3) Tests have established a feasible method for modeling the drift and deformation of individual floes. The results show qualitatively the manner in which individual flows interact as they pass through a constriction. The results form a basis for quantifying the role of floe sizes on the dynamics of ice covers. The report includes suggestions for employing the present conclusions in subsequent efforts towards achieving the ultimate objectives of the overall project.

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.
