Résumé

Le comportement vocal de la baleine à bec de Blainville (Mesoplodon densirostris) a été mesuré à l’aide d’hydrophones installés sur le fond marin, au Centre d’évaluation et de tests sous-marins de l’Atlantique (AUTEC, de l’anglais Atlantic Undersea Test and Evaluation Center) des Bahamas. Les statistiques relatives à la durée des signaux acoustiques et les périodes qui s’écoulent entre les périodes de « chant » ont été mesurées pour des plongées multiples en profondeur (en comportement de recherche de nourriture). La taille des groupes de M. densirostris en recherche de nourriture ont été estimés d’après la durée des périodes de chant en plongée, en appliquant le taux de « clics » et des statistiques sur le rapport de détection dérivés des enregistrements numériques du DTags de la WHOI (Woods Hole Oceanographic Institution), afin de visualiser les données recueillies au centre AUTEC.
