In order to observe the underwater behavior of sperm whales, the authors previously introduced a passive acoustic system that consists of an AUV (Autonomou Underwater Vehicle) with a hydrophone array and two arrays attached to a support ship. The three arrays receive sperm whale clilicks and determine the direction to the sound source by a SBL (Short Baseline) system. Based on triangulation with a...
Sperm whales are known to dive to a depth of over two thousand meters. They emit loud impulsive broadband sounds called "clicks" during their diving. To investigate the sperm whale behavior, we attempt to apply the autonomous underwater vehicle (AUV) as an observation platform for sperm whales. AUV recognizes sperm whales individually and tracks them by listening to their clicks. As an initial...
