Underwater noise pollution from shipping is an increasingly recognized threat to marine ecosystems, particularly for species that rely on sound for communication, navigation, and feeding. As global trade continues to expand, addressing the environmental impact of noise generated by shipping is becoming an important focus for both industry and regulatory bodies. The second roundtable on underwater noise and shipping brought together a diverse group of stakeholders to tackle this pressing issue and explore solutions for mitigating underwater noise in our oceans.
Each year, between 80 - 90% of products and commodities in global trade are transported by ships. Worldwide, the international commercial fleet numbers over 100.000 vessels. Given the scale of this activity, it may come as no surprise that commercial shipping is the leading source of underwater noise pollution in the ocean, which can cause stress, disrupt foraging, and lead to health issues for marine life.
Latest knowledge on underwater sound measurements
For this reason, the federal Maritime and Hydographic Agency (BSH) in Germany, in collaboration with its partners, organized the second roundtable on underwater noise and shipping in Hamburg.
During the roundtable, experts shared the latest knowledge and findings on underwater sound measurements in the Exclusive Economic Zone (EEZ) of the North Sea and Baltic Sea. Besides, technological innovations aimed at reducing ship-based underwater sound were discussed. As a follow-up to an earlier round table, it was decided to further investigate incentive systems for shipping to reduce underwater noise.
With an overall attendance of around 60 stakeholders, representing sectors such as shipping, industry, NGOs and authorities, the second roundtable was a great success.
