This survey was performed to record the noise levels emitted during installation. The levels were measured at different distances from the piles and results were compared to the outputs of a prior modelling outcome. The report in this series presents the results and subsequent analysis of the underwater noise data recorded in this survey. The data was analysed using signal processing and acoustic propagation modelling for the survey region and Source Levels based on recorded data were reported. The underwater noise levels were recorded using two calibrated Acoustic Recording Units (ARUs) deployed at 500 m and 750 m from the foundations along pre-defined transects. In addition to ARUs, a Vertical Sound Profiling (VSP) system with a hydrophone was deployed from the starboard side of the noise monitoring vessel at distances between 4 km and 12 km. The recorded data was processed using peak detection algorithms to identify individual strike data and these are matched with relevant hammer strikes. The matched strikes were post-processed into different frequency bands and their Received noise Levels (RL) were calculated. http://www.marinedataexchange.co.uk/pages/terms-of-use.aspx otherRestrictions http://www.marinedataexchange.co.uk/pages/terms-of-use.aspx otherRestrictions The Crown Estate +44 020 7851 5000 enquiries@thecrownestate.co.uk custodian SHL Offshore Contractors BV unknown unknown originator The Crown Estate +44 020 7851 5000 enquiries@thecrownestate.co.uk distributor Triton Knoll Offshore Wind Farm Limited info@tritonknoll.co.uk owner notPlanned Database Digital Audio https://www.marinedataexchange.co.uk/details/TCE-2132/summary A link to the web service or dataset. https://www.marinedataexchange.co.uk A link to the general host site.

In some instances, this compliance will not be feasible. True series In accordance with the site license, the monitoring and recording of underwater noise generated by the percussive piling events for installation 8.5 m diameter monopile foundations, was carried out by Seiche Ltd. during the installation of the first four foundations. The objective was to follow the methodology in accordance with the best practice underwater noise guidance and standards including those from CEFAS, MMO, and NPL [1]. The overall objective for the noise monitoring plan (document reference: 2505-TKN-CON-KRA- 3037145) is to validate the previous predictions and assess impacts on marine fauna using recorded audio data. The key objective is therefore to characterise the sound source as a function of the range and to compare this value with established recommendations.
