Target description |
As far as possible, marine mammals under the Habitats Directive are not exposed to impulsive sounds that lead to permanent hearing loss (PTS). The limit value for PTS is currently assessed as 200 and 190 dB re.1 uPa2s SEL for seals and porpoise, respec-tively (the best knowledge currently available is on these species). However, it is likely that these limits will be revised as new knowledge on this field becomes available. The values are the sound-exposure level accumulated over two hours. |
Anthropogenic activities causing impulse sound are planned such that direct adverse effects on vulnerable populations of marine animals from the spatial distribution, temporal extent, and levels of anthropogenic impulsive sound are avoided as far as possible and such that these effects are assessed not to have long-term adverse effects on population levels. |
Activities by the authorities under the Ministry of Defence that cause impulse noise in the marine environment are, as far as possible, being assessed and adapted to reduce possible adverse effects on marine animals under the Habitats Directive, provided this does not conflict with national security or defence objectives. Defence Command Denmark applies current NATO standards when carrying out environmental assessments. |
When conducting preliminary seismic studies, adequate remedial action is taken in accordance with the Danish Energy Agency's guidelines on standard terms and conditions for preliminary studies at sea. |
The Ministry of Environment and Food contributes to work regionally and in the EU regarding establishment of threshold values and determination of good environmental status, and is working to ensure that the level of underwater noise is in accordance here-to. |
In connection with licensing offshore activities requiring an environmental impact assessment (EIA), the approval authority is encouraging reporting to the Danish Environmental Protection Agency (monitoring programme) of registrations of impulse noise. (Operational target) |
Through increased monitoring, the Ministry of Environment and Food is improving knowledge about the extent and levels of low-frequency noise in the Baltic Sea and the North Sea. (Operational target) |

As far as possible, marine animals under the Habitats Directive have not been exposed to impulse sounds that cause permanent hearing damage.
|
Anthropogenic activities causing impulse sound were planned such that direct adverse effects on vulnerable populations of marine animals of anthropogenic impulsive sound were avoided. |
Activities by the authorities under the Ministry of Defence that cause impulse noise in the marine environment were, as far as possible, being assessed and adapted. |
Adequate remedial action is taken in accordance with the Danish Energy Agency's guidelines. |
Denmark has contributed to the establishment of thresholds and has participated in coordination work at EU/RSC/international-level. |
