A Belgian campaign for a quieter North Sea
On May 16, 2025, Belgium launched a national awareness campaign aimed at reducing underwater noise pollution in the North Sea. This initiative, developed by the Directorate-General for Navigation (SPF Mobility and Transport), in collaboration with the Marine Environment Service (SPF Public Health) and the Flanders Marine Institute (VLIZ), highlights the impact of marine noise on wildlife and proposes concrete, science-backed solutions to mitigate it.
The effects of underwater noise on marine life
Underwater noise is an underestimated but significant threat to marine ecosystems. It disrupts communication, mating, and feeding behaviors in many species. Invertebrates, fish, and marine mammals alike are affected, with consequences ranging from impaired growth and disorientation to physiological damage and even death in extreme cases.
Concrete solutions for a quieter marine environment
The campaign promotes the use of quieter ships and modern technologies to reduce vessel-generated noise, especially during offshore activities such as construction and resource exploration. Proposed measures include installing more efficient propellers, maintaining balanced and clean propulsion systems, and adopting electric or hybrid propulsion. These solutions not only cut underwater noise but also reduce air pollution.
A model for other countries to follow
With this campaign, Belgium aims to contribute to a healthier North Sea and inspire other coastal nations to take similar actions. The official website www.bruitsousmarin.be provides educational resources, including infographics, posters, and flyers explaining the sources, consequences, and solutions to underwater noise pollution.
Conclusion
Belgium’s initiative demonstrates the importance of raising awareness and taking action to protect marine ecosystems from human-generated noise. By adopting quieter technologies and implementing appropriate regulations, it is possible to significantly reduce ocean noise and its harmful effects on wildlife.
