The sounds of the sea become study tools to reveal the secrets of submerged ecosystems. An innovative project has been launched echo-acoustic monitoring inProtected Marine Area of Punta Campanella, located in the Sorrento peninsula, thanks to the collaboration with the Zoological Station A. Dohrn.
Un hydrophone, a sophisticated underwater microphone, has been installed on the seabed to capture sounds produced by living organisms, natural phenomena and human activities. This technology allows us to listen to underwater “soundscapes”, a mix of biological sounds – such as those of invertebrates, fish and cetaceans –, geophysical sounds – waves, wind and rain – and anthropogenic sounds, such as boat engines, fishing and maritime traffic.
The project is based on theacoustic ecology, an emerging discipline that studies soundscapes to monitor biodiversity, animal activity and human pressure on the ecosystem. “Discreet monitoring, with no environmental impact, that offers extended data over time”, ha sottolineato Lucio Cacace, president of the Marine Protected Area.
The data collected will allow us to identify particularly delicate periods, such as those of courtship and reproduction of some marine species, or to detect peaks of human activity. This information will be essential to adopt targeted protection measures, regulate maritime traffic and safeguard the most vulnerable habitats.
Particular attention will be paid to cetaceans, such as dolphins and fin whales, which depend on sound for communication, navigation and hunting. These animals are highly sensitive tonoise pollution generated by maritime traffic, a growing problem in coastal waters. “This project will help us better understand the impact of human activities and identify mitigation strategies”, has explained Francis Caruso, project manager for the Stazione Zoologica A. Dohrn.
The Punta Campanella Marine Protected Area confirms itself as a natural laboratory for scientific research. This sound monitoring will not only enrich knowledge about marine ecosystems, but will also help raise public awareness about the importance of protecting biodiversity.
“A project that combines science, technology and awareness to protect our sea”, added Caruso. The tools and data obtained will serve to define more effective management measures, for the benefit of both the environment and future generations. With this initiative, theAMP Campanella Point is at the forefront of marine conservation, demonstrating how innovation can become a valuable ally in safeguarding underwater ecosystems.
