Translation of "Bruit sous-marin " (French → English) :

The aim is to reduce the impact on the marine environment (e.g. underwater noise and introduction of invasive species and pollutants from sea and land) and to minimise the carbon foot-print of human activities.

Proportion of days and their distribution within a calendar year over areas of a determined surface, as well as their spatial distribution, in which anthropogenic sound sources exceed levels that are likely to entail significant impact on marine animals measured as Sound Exposure Level (in dB re 1μPa.s) or as peak sound pressure level (in dB re 1μPapeak) at one metre, measured over the frequency band 10 Hz to 10 kHz (11.1.1)

Perhaps we should take our lead on this issue from the November 2004 resolution of the 16 member states of the Agreement for the Conservation of Marine Mammals in the Black Sea, Mediterranean Sea and adjoining Atlantic area, which called for " extreme caution" in conducting activities that produce intense underwater noise.

the fact that the understanding of the impact of climate change is still developing and the issue might come to dominate, the need to pay more attention to i.a. the impacts from pollution of land-based sources, in particular with regard to acidification and eutrophication, leisure, tourism and to underwater noise, the need for supporting scientific research and full access to scientific data, the impact of shipping, including further development that overarch various aspects (such as ballast water, marine litter and air pollution), the clean scrapping of vessels, the need for applying the ecosystem approach to the management of human ac ...[+++]tivities in the marine environment, the need to integrate its current and future socio and economic dimensions of the implementation of the Marine Strategy;

a. Systems that attenuate underwater noise at frequencies below 500 Hz and consist of compound acoustic mounts for the acoustic isolation of diesel engines, diesel generator sets, gas turbines, gas turbine generator sets, propulsion motors or propulsion reduction gears, specially designed for sound or vibration isolation, having an intermediate mass exceeding 30 % of the equipment to be mounted;
