Abstract

fetched live from OpenAlex

Little is known of the westward fall migration of white whales out of the Beaufort Sea. Fraker et al. (1978:41) mention only two records of presumed fall-migrating white whales in this area: (1) approximately 2000 westward-moving white whales near Herschel Island, Yukon Territory, on 21 September 1972; and (2) approximately 100 white whales near the edge of the pack-ice east of Point Barrow, Alaska, also on 21 September 1972. It is unknown whether fall migration takes place along the coast or offshore or both in the pack-ice. In mid- to late September 1977 and 1978, during the course of aerial surveys. along the Alaskan Beaufort Sea coast, white whales were observed migrating westward at coastal locations seaward of Jones Islands, Alaska. On 15 September 1977, at approximately 13:30 Alaska Daylight Time, approximately 75-100 white whales were observed swimming westward 50-300 m seaward of the western end of Pingok Island (70’34’N; 149’35’W), Alaska; some young-of-the-year were present in this group. Approximately 200

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.
