Cost-Effective Architectures For Underwater Sound-Recording Systems

Dolphin presence is typically monitored through Passive Acoustic Monitoring (PAM), deploying underwater devices. Commercial systems incur substantial costs, leading researchers to try to devise cost-effective sound recorders. While cost-efficient, enhancing recorder performance is crucial. The current study is designed to introduce and validate costeffective underwater sound-recording architectures. The test against a commercial system revealed minimal impact on recording performance. These systems, with a few-euro cost, proved highly economical compared to commercial options. The current technology provides a viable, budget-friendly solution for global continuous dolphin monitoring, offering valuable prospects for future studies and applications in marine environments.
