Sea state events in the marginal ice zone with TerraSAR-X satellite images
Bibliographic record
Abstract
With ice properties being changed by the breakup of ice floes, the penetration of ocean waves into the marginal ice zone (MIZ) has a variety of potential effects on the global Earth and climate system. In the last decades, the wave propagation in ice has been studied by in situ measurements, satellite imagery, and laboratory experiments using ice tanks. As well, different theoretical models of the behaviour of waves in ice have been developed. We focus on events of long swell waves encountering the MIZ, mainly on the northern hemisphere. Images from the TerraSAR-X (TS-X) satellite are used to investigate the progression of waves and their behaviour in ice. The included TS-X scenes were acquired in Stripmap mode and are up to few hundred kilometres in length. In particular, the spatial variability of wave parameters through the MIZ is analysed. This yields valuable clues on the interaction between ocean waves and sea ice. Satellite Data acquired during the Sikuliaq Cruise into the Arctic are used to demonstrate the effect of sea ice and ocean wave interaction.

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.
