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 long-term 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.
被动声监测技术的发展和广泛应用,有可能帮助评估人为噪声对海洋生物和生态系统的大规模影响。深海观测站有可能在理解这些最新声学变化方面发挥关键作用。LIDO(监听深海环境)是一个国际项目,它允许在有缆和独立观测站实时长期监测海洋环境噪声和海洋哺乳动物的声音。在这里,我们介绍了该项目的整体发展情况以及被动声监测(PAM)技术的使用,以便为科学界提供大空间和大时间尺度的实时数据。特别关注的是提取和识别高频鲸目动物回声定位信号,因为在缓解过程中,例如在军事演习中,检测目标物种(如喙鲸)具有重要意义。
