Abstract

fetched live from OpenAlex

The catch history of the North Atlantic right whales (Eubalaena glacialis) in the western North Atlantic has been studied in a series ofprojects. Data from European archives on early Basque whaling, centred in the Strait of Belle Isle, showed that there were at least a fewthousand right whales in the northern part of the range in the sixteenth century. Data from shore whaling in the eastern United Statessupplemented by British customs data indicated that there were still more than a thousand right whales in the southern part of the range(i.e. south from Nova Scotia) in the late seventeenth century. Right whales were depleted throughout the western North Atlantic by themiddle of the eighteenth century, but small shore whaling enterprises persisted in some areas and pelagic whalers continued to kill rightwhales opportunistically. An increase in alongshore whaling occurred at Long Island (New York) beginning in the 1850s and in North andSouth Carolina, Georgia and northern Florida in the 1870s-1880s. By the start of the twentieth century only a few crews of shore whalersremained active in Long Island and North Carolina, and their whaling efforts were desultory. All evidence points to stock depletion as theprimary reason for the demise of organised whaling for right whales in eastern North America. Recent sightings indicate that some rightwhales travel from the Bay of Fundy and Scotian Shelf far to the north and east, at least occasionally reaching the historic Cape FarewellGround. Areas known to have been used regularly by right whales in the past (e.g. Gulf of St Lawrence, Delaware Bay) are now visitedseasonally by only a few individuals. Recent surveys of Cintra Bay, a historic right whale wintering ground in the eastern North Atlantic,provided no evidence of continued use by right whales.

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.
