Metadata: 2010, SEAMARCO, Acoustic Mitigation Devices (AMDs) to Deter Marine Mammals from Pile Driving Areas at Sea
Abstract:
For the sustainable development of the offshore renewable energy industry, it is necessary to reduce or avoid the damaging effects of noise (such as death or permanent hearing damage), from activities which produce high sound pressure levels, such as pile driving, on marine mammals. One way to achieve this is to ensure that marine mammals are not present in areas where loud noises are being produced, by deterring them by means of safe sounds produced by Acoustic Mitigation Devices (AMDs). Research is needed to determine whether AMDs can mitigate immediate vicinity impacts of loud sounds, which could give rise to temporary or permanent hearing damage, injury or death of marine mammals. In the North Sea, the two most abundant marine mammal species are the harbour porpoise (Phocoena phocoena) and the harbour seal (Phoca vitulina). COWRIE commissioned SEAMARCO to carry out four studies on the audibility of sounds produced by three selected AMDs and their effect on the behaviour of harbour porpoises and harbour seals (playback experiments). In addition to achieving these aims, SEAMARCO estimated the distances at which sounds from AMDs are audible to, and elicit behavioural responses in, harbour porpoises and harbour seals.

| Abstract | The abstract provides a clear and brief statement of the content of the resource. | For the sustainable development of the offshore renewable energy industry, it is necessary to reduce or avoid the damaging effects of noise (such as death or permanent hearing damage), from activities which produce high sound pressure levels, such as pile driving, on marine mammals.

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | The goals of the research can be summarised as follows: • Determine the audibility (hearing thresholds) of AMD sounds for harbour porpoises and harbour seals • Determine the behavioural response (avoidance thresholds) of harbour porpoises and harbour seals to AMD sounds • Compare the hearing thresholds for the AMD sounds with the tonal thresholds (can hearing thresholds of broadband signals be predicted from hearing thresholds for tonal sounds?) • Estimate the distance at which AMD sounds can be heard by harbour porpoises and harbour seals at sea • Estimate the distance at which AMDs cause a behavioural response in harbour porpoises and harbour seals at sea. The overall purpose of the research was to contribute towards the optimal use of AMDs to deter marine mammals from pile driving sites. The results will inform the selection of the optimum signal parameters of AMDs for deterring harbour porpoises and harbour seals sufficiently far from pile driving areas at sea before pile driving begins, so that wild porpoises’ and seals’ hearing will not be compromised. |
