Autonomous acoustic surveillance system for nearshore soundscaping

Abstract

In response to global climate change and growing industry capabilities, researchers are looking for robust and soft engineered solutions for nearshore ecosystems. A newly developed Multifunctional Artificial Reef is capable of performing several functions within one structure, among which is marine ecosystem restoration and the support for various sensors for structural and environmental monitoring. Combining such functionalities, implementation of passive acoustic shows great potential for biodiversity monitoring and colonization process observation of recently deployed artificial structure. Therefore, by integrating moored hydrophone within the artificial reef system and setting recording mode as well as post processing optimization, peculiar features of local marine habitat behaviour will be researched in order to provide better insight on the contribution of these structures for ecosystems preservation.
