Listening to the Deep: Live monitoring of ocean noise and cetacean acoustic signals

► This paper describes the LIDO real-time acoustic data management. ► LIDO stands for “Listening to the Deep-Ocean Environment”. ► LIDO is an international approach to apply and extend real-time PAM techniques. ► LIDO monitors ocean noise at a global scale. ► The system is applied to cabled observatories and stand-alone buoys for noise mitigation.
