Toward a comprehensive assessment of the disturbance of marine ecosystems by anthropogenic underwater noise

Proposals should:

• develop new, or improve upon existing, scientific methods and tools for comprehensively monitoring the impacts of anthropogenic underwater noise pollution on marine ecosystems and species populations at different trophic levels and taking into account regional differences;
• develop new, or improve upon existing, indicators for the assessment of the effects of noise exposure as well as their cumulative effects on marine organisms and ecosystems, and the services they provide, in line with methods (including threshold values) already agreed at EU level for the assessment of good environmental status for underwater noise and taking into account regional developments;
• investigate options for mitigation measures for safeguarding relevant ecosystem services, including carbon sequestration, and develop or improve tools to measure their impacts and efficiency.

Proposals should support the objective and implementation of the Marine Strategy Framework Directive (MSFD) by providing new evidence and data on the impacts of noise on marine ecosystems and related ecosystem services, in line with the MSFD guidelines for impulsive and continuous noise monitoring, and by providing evidence-based methods for the assessment of good environmental status for underwater noise at national, regional and EU level.

The European Commission signed on behalf of the European Union a Declaration for a High-Ambition Coalition for a Quiet Ocean at UNOC 3 which includes actions to address underwater noise and mitigate its impact on marine life and biodiversity. With a view of supporting the implementation of this Declaration, proposals are expected to contribute to restore a quieter ocean.
