Résumé

La détection et la localisation de mammifères marins à l'aide de l'acoustique passive est explorée pour deux habitats critiques dans l'est du Canada. La technique de localisation par hyperboles en deux dimensions est utilisée à partir des différences de temps d'arrivée à des réseaux de systèmes d'enregistrements autonomes largement espacés, ainsi qu'à un réseau serré d'hydrophones reliés à la côte. Les délais d'arrivée sont calculés par inter-corrélation ainsi que par inter-coincidence des spectrogrammes des signaux rehaussés par des techniques de rehaussement des hautes fréquences et de soustraction spectrale du bruit. Les résultats et la performance relative des deux méthodes sont comparés. Les difficultés rencontrées dans le contexte des conditions particulières de ces deux environnements sont discutées par rapport à l'automatisation de la localisation pour le monitorage des baleines.
