Migration timing metrics of 11 Atlantic salmon populations in Eastern Canada
Bibliographic record
Abstract
This dataset contains migration timing metadata for Atlantic salmon (Salmo salar) populations across 11 rivers in eastern Canada, spanning the regions of Labrador, Newfoundland, and the Maritimes. For each site, the dataset includes geographic coordinates, the Julian day at which 5 % and 95 % of the cumulative annual run was reached, and the run-timing modality (unimodal or bimodal). Populations vary widely in migration timing, with early runs beginning as early as day 145 and late runs extending beyond day 288. Bimodal populations, found primarily in the Maritimes, display two distinct peaks in migration timing, whereas unimodal populations in Labrador and Newfoundland have a single, more continuous run. These data provide baseline information on spatial variation in run timing and migration modality in North American Atlantic salmon, enabling integration with genetic, environmental, and climate projections to investigate the ecological and evolutionary drivers of migration phenology.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
