Defining Canada’s Extended Continental Shelves
Bibliographic record
Abstract
Article 76 of the United Nations Convention on the Law of the Sea provides a process to delineate Canada’s continental shelf where it extends beyond 200 nautical miles. After ratification of the Convention in 2003, Canada started a program to acquire and analyze the scientific data required for a submission to the Commission on the limits of the continental shelf. This submission will assist Canada in defining the outer limits of its continental shelf, thereby determining, with precision, the area where Canada may exercise its sovereign rights over natural resources. This paper outlines the scope of that program and summarizes the scientific activities to date. Data collection along the Atlantic margin was completed according to plan and the data are presently being analyzed. Data collection in the Arctic has been challenging because of ice and weather conditions, and several innovative solutions were implemented to collect seismic and bathymetry data using ice-breakers and large ice camps. The narrow Pacific margin provides no clear prospects for an extended continental shelf. Overall, the program is on schedule to meet the December 2013 deadline for submission to the Commission. SOMMAIRE L’article 76 de la Convention des Nations Unies sur le droit de la mer comporte une procedure permettant de definir l’etendue du plateau continental canadien au-dela des 200 miles nautiques. Apres ratification de la Convention en 2003, le Canada a lance un programme d’acquisition et d’analyse des donnees scientifiques exigees par la Commission pour definir les limites du plateau continental. Le depot de ces donnees aidera le Canada a definir les limites exterieures de son plateau continental, et donc, de deter-miner precisement le territoire ou il pourra exercer des droits souverains sur les ressources naturelles. Le present article decrit ce programme et resume les activites scientifiques realisees a ce jour. Le long du plateau continental de l’Atlantique la collecte des donnees s’est terminee comme prevu et leur analyse est en cours. Dans l’Arctique, la collecte des donnees n’a pas ete facile en raison de la glace et les conditions meteorologiques, et plusieurs solutions innovantes ont dues etre mises en œuvre afin de recueillir des donnees sismiques et bathymetriques, comme l’utilisation de brise-glaces et le recours a de grands camps de glace. Sur la cote du Pacifique, l'etroitesse du plateau continental exclu toutes possibilites d'extension evidemment. En gros, le programme se deroule comme prevu, et la date limite du decembre 2013 pour soumission du dossier a la Commission devrait etre respectee.

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.
