Suivi acoustique passif en temps quasi réel des baleines noires de l'Atlantique Nord (Eubalaena glacialis) à l'aide de planeurs électriques profilants dans le détroit d'Honguedo, golfe du SaintLaurent.
Abstract
An electric glider equipped with a hydrophone system capable of detecting and classifying right whale upcalls in real-time was deployed for a 56-day mission in the Honguedo Strait during September 4th to October 30th, 2019. Two archivally recording passive acoustic moorings were placed along the glider track to compare space-time variation in right whale detections between fixed and mobile platform types. Review of the glider hydrophone data revealed that right whale upcalls were recorded by the glider September 5th and September 10-11th. Upcalls were also recorded on the acoustic mooring during September 10th & 11th. The glider performed very well and is a useful asset to support real-time management in dynamic shipping corridors.
