Abstract
The Baffinland (BIM) Mary River Project is an operating open-pit iron ore mine located on North Baffin Island in Nunavut. As part of their project certificate, annual surveys of narwhal (Monodon monoceros) have been conducted by Golder Associates Ltd. (hereafter Golder) and WSP Canada Inc. (hereafter WSP) in Eclipse Sound and Admiralty Inlet in August 2019, 2020, 2021 (Golder Associates Ltd. 2020a, 2021, 2022), and 2022 and 2023 (WSP Canada Inc. 2023, 2024). Fisheries and Oceans Canada (DFO) Science is responsible for providing advice on the sustainable hunt of these stocks. DFO surveys and subsequent population modelling rely on surveying narwhal aggregations when they are in their summering grounds. A time series of abundance estimates provides robust population dynamics modeling for stock assessment. Therefore, this document reviews the Golder-WSP surveys and resulting abundance estimates for use in future population dynamics models. Golder-WSP conducted surveys during the open water and shoulder seasons (before ice break-up in the spring and after ice formation in the fall); this review focuses only on those surveys in the open water season (namely August). The August surveys conducted by Golder-WSP are described briefly and reviewed here. Recommendations on final abundance estimates that could be included in future population dynamics models are presented. This Science Response Report results from the regional peer review on October 16, 2024, for the Science Review of Narwhal (Monodon monoceros) Surveys Conducted by Golder-WSP in 2019-2023 for use in DFO Fisheries Stock Assessments.

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.
