Passive acoustic storey of the Antares neutrino detector for real-time cetaceans detection, localization and behavior studies

Passive acoustics is one of the methods for marine mammal observations. This approach is complementary of visual observations or use of tags. Different projects for marine mammals' acoustics observatory (permanent or mobile) are actually in construction. A part of them are included in biggest multidisciplinary projects and especially in geophysics projects. We join the Antares project for at least 2 reasons. Firstly, the Antares neutrino detector is built in one of the Mediterranean Sea hotspots. Secondly, many sensors is used for this neutrino detector and especially hydrophones with appropriate bandwidth for marine mammal observations. We first briefly present the ESONET Network and then the ANTARES telescope. We then illustrate the real-time analyses that we can run on ANTARES data. We finaly discuss on the ANTARES extensions in the Ligure Sea and its impact on cetacean studies monitoring.
