Abstract

fetched live from OpenAlex

Abstract Ice forms in water bodies under the influence of climate, oceanography, and the geography of the surrounding land. It grows as a result of thermal processes and mechanical processes. First‐year level sea ice can grow thermally to a maximum thickness of about 2 and 2.5 m in extreme winters. Ice floes interacting with each other can build accumulations of broken ice, ridges, which can attain sail heights of 5 m and keel depths of 25 m, but are usually smaller. In some seas, the ice does not completely melt in summer and perennial accumulation of deformed multi‐year ice can reach thicknesses greater than 10 m. Large seasonal and interannular variations in ice are normal and superimposed on them are the effects of longer term climate changes. Different sea areas have varying combinations of these ice types throughout the year. The likely ice conditions encountered in various sea areas of interest for marine and offshore operations are described.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
