In this episode of BlueTech Around the World, we dive deep into the rising issue of underwater noise pollution, a silent but widespread threat caused by human activities like shipping, port construction, and offshore energy.

Beneath the waves, what was once called the “silent world” is now buzzing with noise that disrupts communication, navigation, and survival for marine species.

To unpack the challenge and explore cutting-edge solutions, I’m joined by Gwenaël Desse, Chief Business Officer at Greenov, the French startup behind the SubSea Quieter, a patented mitigation system that reduces noise and turbidity during offshore and coastal operations.

With a unique path from naval defense to ocean protection, Gwenaël shares how Greenov’s patented technology reduces harmful noise from pile driving, port works, and vessel operations while offering measurable business and environmental benefits.

🔹 In this episode:

• Why ocean noise matters  and how it impacts whales, dolphins, fish, and marine ecosystems
• How the SubSea Quieter works
• Business case: reduced operational costs, emissions, and acoustic risks
• Integrating noise mitigation in a broader ecosystem of marine protection
• What’s next in innovation: real-time monitoring, deep-water adaptation, and metamaterials
