The Battle to Quiet the Sea: Can the Shipping Industry Turn Down the Volume?
- The IMO launched the GloNoise Partnership with UNDP and GEF to reduce shipping noise in pilot countries, announced at UNOC3 in Nice.
- This initiative responds to the growing underwater noise from shipping, which harms sensitive marine areas and vulnerable indigenous communities.
- The partnership promotes new technologies like hull cleaning, better propellers, and speed optimization to lessen underwater radiated noise.
- In 2023, the IMO revised its voluntary guidelines, providing shipbuilders and operators with various technical suggestions covering aspects such as hull configuration, propeller efficiency, and operational practices like slowing vessel speed.
- These efforts aim to mitigate the intensifying impact of noise on marine ecosystems, signaling a move towards tangible ocean protection commitments.

A coalition of 37 countries, led by Panama and Canada, pledged on Monday in Nice (southeastern France) to combat an important but invisible threat: the noise pollution of maritime transport, which harms many marine species. Whales, dolphins, fish and many other marine species are seriously affected by this type of underwater pollution, which interferes with their ability to guide, communicate, hunt, breed and prevent predators. Coalition members…
The coalition wants to combat the noise pollution of maritime transport, which harms several underwater species.
Biophony, geophony and anthropophony: underwater environments are sound. Decrypting these deep-sea signals is necessary to improve the understanding of the behaviors and interactions between specimens, as well as their disturbances. But how can we manage to capture them over time?

The battle to quiet the sea: Can the shipping industry turn down the volume?
The ocean has never been silent – waves crashing, seabirds calling, whales singing across vast distances. But in recent decades, a new kind of noise has taken hold: the relentless hum of ships. For many marine species, this growing wall of sound is more than a nuisance – it’s a threat to their survival.
Draft Environment, 10 Jun (EFE).- Panama and Canada have presented this Tuesday at the third Ocean Summit in Nice (France) the Coalition of High Ambition for a Silent Ocean, an initiative to which 35 countries, including the 27 of the European Union, have joined, with Spain represented by the minister for the Ecological Transition, Sara Aagesen. It is the first global political coalition dedicated to reducing underwater acoustic pollution produc…
The ocean has its own sound world. But the human being disturbs the inhabitants of the sea with its noise in communication. Germany and other states want to change this – and joined forces at the UN Ocean Conference in Nice.
