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

<p class="topicdescriptionkind">

Expected Outcome

</p><p>Project results are expected to contribute to all of the following expected outcomes:</p><ul level="0"><li>impacts of continuous and impulsive underwater noise levels on marine organisms and ecosystems, and the related ecosystem services they provide, including cumulative impacts with other pressures, are well understood, taking into account regional differences;</li><li>environmental authorities have access to advanced methods, tools and indicators enabling them to comprehensively monitor and assess the impacts of underwater noise pollution on marine species and ecosystems and to devise strategies for protecting the ecosystems services they provide.</li> </ul><p class="topicdescriptionkind">

Scope

</p><p>Proposals should:</p><ul level="0"><li>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;</li><li>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;</li><li>investigate options for mitigation measures for safeguarding relevant ecosystem services, including carbon sequestration, and develop or improve tools to measure their impacts and efficiency.</li> </ul><p>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.</p><p>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.</p>
