Harmonized Shipping Sound Test Signals to Assess Effects on Aquatic Animals
bookPart
One of the main aims of the EU Horizon 2020 research program SATURN
(developing solutions to underwater radiated noise, https://www.saturnh2020.eu/)
is to determine the relevant metrics of ship-radiated underwater sounds that can be
related to effects on the physiology and behavior of aquatic animals. Where
possible, these metrics will then be related to the corresponding ship design and
operational parameters, to enable the development of mitigation solutions. As part
of the approach, controlled exposure experiments will be conducted on representative
fish and invertebrate species, involving playback of these representative test
signals.
The relevant temporal and spectral features that can be attributed to shipradiated
sound characteristics have been characterized, based on data available in
the literature. A suite of artificially synthesized ship sound signals has been
developed. These signals are considered suitable for the assessment of harmful underwater
noise characteristics in the sense that they are relevant for the impact
on marine life as well as subject to technically achievable mitigation measures.
Using harmonized test signals in different bioacoustic playback studies facilitates
the comparability of results. These signals are offered as a standard reference for
external stakeholders and future projects.
