12 GDD Project Irish Water GDD Greater Dublin Drainage Project

13 GDD - Project background N TechWorks Marine were contracted by Irish Water to collect the following over a 2 year period: Turbidity and TSM data Acoustic survey and Noise Model Marine mammal observations (sub-contracted to IWDG) Wave and current survey Acoustic data collected using an iclisten The location of the GDD monitoring buoys were along the proposed pathway of the pipeline route (see map).

14 Project background Sites GDD1 and GDD2 had a single IWDG s CPOD static acoustic monitor each (SAMS), whereas site GDD3 also had a Seapoint Turbidity sensor mounted on a Seabird 16 Plus CT (Conductivity/ temperature) sensor on the mooring (see above)

15 GDD LAB noise model Impact Noise Analysis An ICListen was deployed on GDD 3. It was operating continuously from July 30 to September 1. This data was then provided to Laboratori d'aplicacions Bioacústiques (LAB), Barcelona for analysis. The recording duty cycle was configured to: 15 minutes on and 50 minutes off. The hydrophone sensitivity taken from the stored wav files was -168 db re 1 V/ µpa. The data was sampled at 16 khz in 24 bits; the quantization was between +-3V. No gain was used. The measured levels during August appear to have little variation. The data analysis indicates that dominant influences on the measured levels were wind speeds and perhaps water currents. Both may have produced typical sounds of moving cables. No cetaceans were detected; the contribution of biological sources appears to be minimal in these recordings.

16 GDD Sub-contractors Acoustic Modelling In addition to the analysis of the data recorded during August 2015 the data was used to create a map of the noise propagation of the dredging activity at one specific position for three frequencies: 125Hz, 1kHz and 8kHz third octave as defined by the international standards for a single environmental study.

17 Dublin Port (ABR Project) ABR Dublin Bay Alexandra Basin Redevelopment Project

18 ABR- Project Overview Multi-annual deployment of 4 state-of-the-art real-time data buoys ( ): TWM 1: Real-time Turbidity (3 water depths) Real-time Hydrophone (PAM) system TWM 2: Real-time Turbidity (3 water depths) Real-time Hydrophone (PAM) system Spectral Wave and through water Current Profile TWM 3: Real-time Turbidity (3 water depths) Control: Real-time Turbidity (3 water depths)

19 ABR- Project Overview Equipment: Best in Class Mobilis Buoy Hull International leader in the provision of buoy hulls (UK MetOffice, Ifremer) TechWorks Marine TMBB buoy controller, used Internationally (SMHI, Marine Institute, DAFM) Seaview Wave Sensor (used by NOAA, CEFAS, Port of Cork) Nortek ADCP, International leaders (NOAA, CEFAS, NOCS) Seapoint Turbidity Sensors, International leader (AFBNI, DAFM) JASCO Observer acoustic system, International leader (Port of Vancouver) TFI Marine Silent moorings

20 ABR Infrastructure

21 ABR Acoustic system Dublin Port wanted to minimise the amount of data buoys used on the project: This led to TechWorks Marine being award the acoustic data provision contract. Two JASCO applied sciences Observer Systems were purchased by TechWorks Marine for the project. The IWDG have been contracted by DPC to carry out all the Marine Mammal work on the ABR including: PAM (Passive acoustic monitoring) analysis. Why PAM? To ensure compliance with NPWS protocols for Marine mammals as part of Dublin Port EPA Dumping at Sea Permit. Innovation Single Metocean and Acoustic Platform Elastomer silent moorings

22 ABR Acoustic system How Does it work: Switched on by remote Marine Mammal Observer (onboard dredging Boat) Marine Mammal Observer (IWDG) uses this instead of visual sighting at night or in poor weather Single Geospectrum hydrophone on each mooring and one spare Once on sends a message (by ) every 2 minutes one message per buoy) To date over 24,000 s

23 ABR Silent Moorings Buoys adapted for PAM acoustics: Sub-contracted TFI Marine to design and supply bespoke silent moorings for two larger buoys. Using novel Elastomer moorings on both buoy with JASCO Observer Systems

24 ABR MetOcean Data CoastEye Data Portal: Flexible: Automated real time data delivery or archive access Any type of data can be included: time-series, spatial, multi-dimensional In-situ module: two-way data acquisition and platform management and monitoring. Bespoke data processing scripts and chain management can be implemented Portal can be web-based or stand-alone with only intranet access Scalable: Spatial database stores raster and vector data with API to fully scalable database Sensor configuration management and control scales with your network Multiple portal instances possible for different applications Secure: Secure logins provided User management, including access control and configuration, is standard Stand-alone versions with only local access can be provided

26 ABR - To Date All four buoy systems are currently running and reporting back live environmental data and acoustic data to the client for the next four years. Buoy 2 recorded waves over 4.5m in Dublin Bay during storm Ophelia Acoustic data being analysed by IWDG at present Passive Heavy Metal sensors to be deployed on the buoys over the coming months. Additional data being collected: Mooring strain gauges Met. Stations. Irradiance (EO data validation)

27 NIAP National Infrastructure Access Programme

28 NIAP Project developed with DIAS in 2016, with aims: -Use SmartBay Buoy to Test latest TMBB Data Logger version -Connected to surface iclisten -Collecting this real-time streamed data with the SeaBed Observatory iclisten (timestamped) -Use data for 2 scientific objectives, linked to ongoing DIAS research.

29 NIAP Objective 1: To develop passive acoustic parameter estimation methodologies as a substitute for active (human generated) acoustic methodologies, where appropriate. (The SmartBay facility is an ideal location in which to test this emerging passive technology for time-lapse water column monitoring as there are independent measurements of the parameters of interest (acoustic wave velocity, currents, temperature, salinity), using active systems at the SmartBay site. If successful, passive methodologies will be rolled out into deeper water) city) estimations. Objective 2: To attempt to test if Cetacean insonification can be used as a passive means of near sea bed sub-sea floor imagery (That is: we will see if acoustic waves generated by Cetaceans can be processed such that they can be used as a high frequency acoustic source for determining properties of the near sea floor.

30 IEC TC 114 Standards IEC TC114

31 IEC TC 114 Marine Energy Wave, tidal and other water current converters International Electrotechnical Commission Technical Committee on Marine Energy Project Team : Acoustic characterization of marine energy converters First Draft Technical Specification due in coming months. Dr. Jenny Hanafin, TechWorks Marine, is chairing the Acoustic project team. Please contact if you are interested in reviewing the Draft and submitting a response before the final Technical Specification is published.

32 IEC TC 114 Marine Energy Wave, tidal and other water current converters Scientific Scope: This Technical Specification provides uniform methodologies to consistently characterize the sound produced by the operation of marine energy converters that generate electricity, including wave, current, and ocean thermal energy converters. This specification does not include the characterization of sound associated with installation, maintenance, or decommissioning of these converters, nor does it establish thresholds for determining environmental impacts. Characterization refers to received levels of sound at particular ranges, depths, and orientations to a marine energy converter. An informative annex provides guidance on additional measurements that would be necessary to estimate source levels. The scope of this specification encompasses methods and instrumentation to characterize sound near marine energy converters, as well as the presentation of this information for use by regulatory agencies, industry, and researchers. Guidance is given for instrumentation calibration, deployment methods around specific types of marine energy converters, analysis procedures, and reporting requirements.

33 Going forward Looking forward to the upcoming NIAP project. TechWorks Marine interested in collected acoustic data as part of larger environmental /MetOcean scope for clients Data as a service including acoustic data for subsequent expert analysis is of interest to us and our client base. After the ABR project is over we will have the two JASCO observer systems for use on other projects/contracts in TWM pool of equipment. Underwater noise for MRE and the TC114 standard development is important. Interested in developing partnerships and collaborations with other parties in this field.

34 Going forward Thank You
