Evaluation of maritime transportation activities in the Canadian Arctic
Bibliographic record
Abstract
This paper aims to provide a better understanding of maritime transport activities in the Canadian Arctic and its evolution since 2002. The methodology is original in the sense that it proposes a threefold analysis based on three different indicators. As well as using the two most common indicators (number of trips to the Canadian Arctic and number of trips within the Canadian Arctic), this contribution is amongst the first attempts to quantify maritime transportation activities in the Canadian Arctic in terms of distances travelled by vessels within the area. This quantification of Canadian Arctic shipping traffics in actual nautical miles travelled partially fills the information gaps resulting from the use of the first two indicators. Indeed the information is necessary for future more accurate evaluation of the footprint of maritime transport on the Canadian Arctic environment and to better understand the risks of navigation in this region. Furthermore, the results detail the nature of the rapid growth in commercial shipping within the Canadian Arctic in recent years. La présente contribution vise à fournir une meilleure compréhension de l’évolution des activités maritimes en Arctique canadien entre 2002. Il s’agit d’une analyse originale puisqu’elle permet de le faire sous trois angles, ou indicateurs, différents. En plus des deux indicateurs le plus souvent utilisés (nombre de voyages vers l’Arctique canadien et nombre de voyages en Arctique canadien), la présente constitue une des premières tentatives pour quantifier l’ampleur du trafic maritime en Arctique canadien et son évolution en fonction des distances parcourues par les navires. Cette analyse comble en partie les lacunes générées par l’utilisation de données relatives au nombre de voyages. En effet, la quantification des trafics en Arctique canadien en termes de milles marins pourra mener à un calcul de l’empreinte du transport maritime sur l’environnement arctique et ainsi mieux cerner les risques de la navigation. Qui plus est, la compilation réalisée détaille la nature de la croissance rapide dans les dernières années de la navigation commerciale dans l’Arctique canadien.

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.
