Study of iceberg scour & risk in the Grand Banks region
Bibliographic record
Abstract
A laboratory program was carried out to measure the loads and seabed response due to a buoyant ice block scouring sand and gravel representative of the Grand Banks seabed, offshore of eastern Newfoundland, Canada. The results complement previous experimental work carried out at the Canadian Hydraulics Centre (CHC), which used a rigidly affixed ice block to scour sediment material [Cold Reg. Sci. Technol. 35 (3)(2002a) 195]. The present study used the same sediment to create a model seabed; however, in this test series, the model was towed along an ice tank, free to move throughout the water column. Six tests were carried out. Freshwater ice, built up into a large block with an overall dimension of 0.76×0.76×0.71 m, was used to scour the seabed at depths up to 0.2 m. The scouring loads, displacement, angular movements and resulting trenches were measured. This paper provides a description of the test arrangement and the experimental results.

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.
