Abstract
The Southwest Fisheries Science Center has been conducting shipboard visual line-transect cetacean surveys for over 30 years, and combined visual and acoustic surveys for seven years. Full incorporation of passive acoustics as a tool for population assessment requires an understanding of the acoustic behavior of cetaceans as well as the limitations of the methods used in these surveys. Our research summarizes data collected during seven years of combined visual and acoustic surveys throughout the central and eastern North Pacific Ocean, ranging from the Aleutian Island chain in the north, to Peru in the south. Phonations from 2.034 dolphin schools were examined to better understand the acoustic behavior of cetaceans. Equally important are the cetacean schools that were seen but not heard, and this analysis includes an examination of these groups by species, group size, geographic location, and time of day. The results of this analysis allow us to take the first steps to incorporate passive acoustics into line-transect cetacean surveys.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
