André, M., van der Schaar, M., Zaugg, S., Houégnigan, L., Sánchez, A.M., Castell, J.V. Listening to the Deep: Live monitoring of ocean noise and cetacean acoustic signals Marine Pollution Bulletin, vol 63, p.18-26, 2011
Résumé:
The development and broad use of passive acoustic monitoring techniques have the potential to help
assessing the large-scale influence of artificial noise on marine organisms and ecosystems. Deep-sea
observatories have the potential to play a key role in understanding these recent acoustic changes. LIDO
(Listening to the Deep Ocean Environment) is an international project that is allowing the real-time longterm
monitoring of marine ambient noise as well as marine mammal sounds at cabled and standalone
observatories. Here, we present the overall development of the project and the use of passive acoustic
monitoring (PAM) techniques to provide the scientific community with real-time data at large spatial
and temporal scales. Special attention is given to the extraction and identification of high frequency cetacean
echolocation signals given the relevance of detecting target species, e.g. beaked whales, in mitigation
processes, e.g. during military exercises.
