Abstract
Underwater calling behavior between breathing bouts of a (presumed) single adult male Weddell seal (Leptonychotes weddellii) was examined at Davis Station, Antarctica. Underwater calls and in-air breathing sounds were recorded on 1 and 8 December. Thirty-six postdive and 37 presurfacing sets of calls were analyzed. Dives were 461±259 s (mean ± S.D.). The seal called every 22.7±21.7 s. The first two calls after diving were at 15.6±9.3 and 33.3±9.7 s. The last two calls occurred at 38.8±32.0 and 22.7±20.1 s before surfacing. The first call after a dive was usually (29/36) a low-frequency growl. One of three patterns of 3–5 call-type sequences was made following 26 of 36 dives. A common four-call sequence was also recorded earlier in the breeding season at this location and was absent at four other distant breeding sites. The timing and call-type sequences of underwater vocalizations after a dive were highly stereotyped, while those before surfacing were not. Territorial males may call throughout each dive and use stereotyped call patterns to identify themselves. [Work supported by Australian Antarctic Division and NSERC.]

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.
