Tidal influence on diel movement of North Atlantic right whales (Eubalaena glacialis) in the Bay of Fundy
Bibliographic record
Abstract
The endangered North Atlantic right whale (Eubalaena glacialis), is known to aggregate in the Bay of Fundy, between New Brunswick and Nova Scotia, Canada to feed during summer. The Bay of Fundy is famous for its extreme tidal range of up to 15 meters, but the effect of these tides on the distribution of whales has not been thoroughly investigated. I hypothesized that the distribution of movements of the whales is influenced by tidal currents, which can average from two to three knots at mid–tide. To test this hypothesis, I queried the North Atlantic Right Whale Catalog of photographically identified individuals and compiled sighting records of animals seen more than once a day in the Bay of Fundy. Paired sightings for each animal were analyzed for time, distance and tidal stage changes between each set of sightings. These results were compared to the hypothetical movement of a passive particle using Canada’s Department of Fisheries and Ocean WebDrogue model. My results indicate that right whales are displaced by the tides. The likelihood that they have remained with a discrete prey patch was correlated with the overall displacement of the whale and the amount of time elapsed. There was a significant correlation between the tidal current direction and the short–term movements of right whales in this habitat area. Understanding how right whales utilize this important habitat area will help inform more effective management decisions.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
