Multi‐Platform Deployments of Low‐Cost Devices for Cetacean Passive Acoustic Monitoring
Remote Sensing in Ecology and Conservation, EarlyView.Recent advances in affordable, user‐friendly devices offer new opportunities to overcome cost constraints of underwater passive acoustic monitoring (PAM) and expand acoustic data collection. In this study, we deployed low‐cost acoustic recorders and underwater cameras across a range of platforms in the Western Mediterranean, including fishing gear ...
