On the 10th of June 2025 at the 3rd UN Ocean Conference (UNOC3), co-hosted by France and Costa Rica, South Africa took the global stage to address a critical yet often overlooked threat to marine ecosystems—Underwater Radiated Noise (URN).
Representing the nation was the South African Maritime Safety Authority (SAMSA), led by Acting CEO Ms. Mbalenhle Golding, who delivered a compelling intervention during a high-level session dedicated to URN. She reaffirmed South Africa’s support for the IMO GloNoise Partnership Project and showcased the country’s proactive efforts, including expanded EIA research and efforts to invest in real-time monitoring capabilities across our coastal and marine environments.
Key Highlights from the Session:
France spotlighted URN as a global environmental priority, with President Emmanuel Macron emphasizing its urgency during his keynote address.
Belgium, Canada, and the European Union echoed calls for binding international frameworks and science-based policies to mitigate URN.
Different experts underscored that commercial shipping is the primary contributor to URN, posing serious risks to marine biodiversity—especially species like whales, dolphins, and fish.
South Africa’s Commitment:
South Africa remains resolute in its commitment to advancing ocean health, aligning with SDG 14: Life Below Water. Through multilateral cooperation, technological innovation, and inclusive policymaking, the nation continues to lead efforts in the Global South to create quieter, more resilient oceans.
