Monitoring strategy description |
The monitoring strategy for D11C1 and D11C2 at the moment is mostly based on several EU projects that are currently taking place and the TG Noise recommendations that will work towards defining threshold values. QuietMED2 project is funded by Directorate-General for Environment, European Commission, it is focused on impulsive noise in the Mediterranean Region, and it will provide practical outcomes through a joint proposal of a candidate for an impulsive noise indicator in the Mediterranean Region and a common methodology for Competent Authorities to establish threshold values, together with associated lists of elements and integration rules. This should lead to an establishment of a joint register of impulsive underwater noise in the Mediterranean Sea Region. Within the project Monitoring and Observation System within the Implementation of the Marine Strategy Framework Directive (MSFD) in Croatia measurements on four positions in two seasonal periods are being carried out regularly. Moreover, Interreg Italy-Croatia project SOUNDSCAPE works on creating a cross-border technical, scientific and institutional cooperation to face the challenge of assessing the impact of underwater environmental noise on the marine fauna and in general on the Northern Adriatic ecosystem. A shared monitoring network is being implemented, that will provide a yearlong continuous noise data in the Northern Adriatic, which will be integrated into modelling tools to create more general view of the soundscapes in the region. |

Gaps and plans |
There is no law on the register of impulsive underwater noise and corresponding data, which is the gap of MSFD implementation in Croatia. At the moment, the text of technical requirements for future law is under preparation. Results of the QuietMED2 project and resulting activities at the national level will help in its adoption. The spatial and temporal resolution of continuous noise monitoring has been significantly improved recently, new instruments were obtained, and additional stations are being used to expand the monitoring network. The upgrades in continuous noise monitoring are also expected through cross-regional cooperation and soundscape modelling. |

Programme description |
Impulsive sounds can lead to a variety of behavioural reactions such as avoidance of feeding or breeding areas, or may result in physiological effects such as temporary or permanent damage to hearing organs, and at very high levels, even death.
Criteria D11C1 will be realized through the establishment of an underwater impulse noise occurrence register. The register should provide information on the number of days within an area where the pulse level is
or a series of noise pulses exceeded a certain threshold. These sound levels refer to the relevant frequency band 10 Hz - 10 kHz. |
Continuous noise may degrade the sound habitat, masking biologically relevant signals such as echolocation clicks, making it harder or impossible to find a mate, locate food or detect predators.
The element of criterion D11C2 will be realized through monitoring the spatial-temporal distribution of low and medium frequency continuous noise levels and trend monitoring. This is possible in two ways:
by measuring and modeling noise propagation. In Commission Decision 2017/848 / EU requires monitoring of the spatial-temporal distribution of levels continuous low and medium frequency noise in tertiary bands of 63 Hz and 125 Hz. As the measurement methodology is such that the measurement is performed in a wider frequency range of 20 Hz - 20 kHz, the parameters to be used in determining the element of criterion D11C2 are the levels of continuous low and medium frequency noise in all third bands within the frequency range of 20 Hz - 10 kHz. Trends will be monitored on all third bands, and also on the overall level within the entire frequency range. |
