Utilisation de la surveillance acoustique passive à partir de planeurs pour la détection en temps quasi réel des baleines noires de l'Atlantique Nord (Eubalaena glacialis) pour supporter la gestion des zones de navigation dynamiques du chenal Laurentien et de la zone de ralentissement volontaire du détroit de Cabot (2021-2022).

Le résumé fourni par la source

This project used right whale detections from gliders to trigger dynamic vessel management in the traffic separation scheme within Dynamic Shipping Zone C (DSZ C) and the Cabot Strait Voluntary Slow Zone. Two profiling gliders equipped with hydrophone systems were deployed for 116 and 107-day missions, respectively, from July 6th – November 9th, 2021. The gliders reported daily detections of four baleen whale species that were validated by a trained human analyst and then sent to Transport Canada. The glider detected right whales in DSZ C on fourteen survey days, and the Cabot Strait on two survey days. In response to the glider detections, a speed limit was imposed in DSZ C for 72 days, or 62.1% of the survey period. The false positive rates for right whale detections at the daily scale were 7% and 0%, and the false negative rates for this species at the daily scale were 5% and 1%, respectively.
