Environmental Impact Assessment of a Global Ocean Listening Network (GOLN): Evaluating Risks to Marine Flora and Fauna and Designing Ecologically Safe Monitoring Systems

The development of a Global Ocean Listening Network (GOLN), powered by distributed Ocean Current Power Units (OCPUs), presents a transformative opportunity for large-scale marine monitoring. However, the deployment of thousands of underwater energy-harvesting turbines and acoustic sensors raises important environmental questions regarding potential impacts on marine ecosystems. This research paper evaluates the ecological risks associated with such infrastructure, focusing on interactions with marine fauna, acoustic disturbance, habitat alteration, and electromagnetic effects. It further proposes mitigation strategies and design improvements that would minimize environmental disruption while maintaining the scientific benefits of a global acoustic monitoring network. By integrating ecological design principles, passive acoustic monitoring techniques, and low-impact marine energy technologies, it is possible to develop an ocean observation system that enhances environmental protection rather than threatening it.
