Abstract
The CCGS Terry Fox field trials produced impacts with growlers, bergy bits and a small iceberg over a range of velocities. Ice mass ranged from 30 t to 22,000 t and velocity from 0.1 m/s to 6.6 m/s. Results have been analysed looking at the effect of speed and ice mass on the measured impact force. There was considerable scatter in the results until the rate of the rise time of the measured impact force was taken into consideration. A trend of increasing impact force with loading rate was observed. To further examine this aspect of rate effect on impact forces, medium scale field indentation tests were also studied, since they were done to simulate full scale impact loading. The tests were done at a number of locations in the Arctic on iceberg ice and multi-year ice, and also showed a rate effect. For the CCGS Terry Fox the maximum force related to the loading rate with the following expression where F is force in MN and is loading rate in MN/s. The expression is supported by data up to a maximum force of 6 MN. Higher forces at comparable loading rates were achieved in the field indentation tests due to higher loading system capacity and better ice-indentor contact.

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.
