Work Packages



Work Package 1: Project Management

This work package will ensure the project is implemented in accordance with best project management practice (IPMI). Work package activities will include administration and reporting (management and financial), organisation of project management meetings, and the establishment of a Project Advisory Group. The main role of this work package is to ensure that project outputs are of the prescribed quality, on schedule, and within budget. The Project Advisory Group for the study has been organised in such a way as to cover the main theoretical and practical requirements for the project, and represents an interdisciplinary approach.


Work Package 2: Data Mining and Data Management

This work package involves a comprehensive data collection exercise on previously licensed activities in the Irish EEZ that produce loud low and mid frequency impulsive sounds. This will include all classes of high intensity impulsive sounds that are known to affect the marine environment adversely. Sounds made by most commercial seismic surveys, by impact pile-driving, by low and mid-frequency sonar and by explosions will be included, whilst depth-finding and most fishery sonar should not be included (see Tasker 2010). Information will be sourced from relevant impact assessments or reports from activities required under national licensing post December 2000. Static environmental data (bathymetry, sediment, sound speed profile, etc) will be collated from various sources (e.g. EUSeaMap, EMODnet) for the purpose of sound modelling in WP3.


Work Package 3: Noise modelling and mapping

This work package will focus on underwater sound mapping and modelling, and is broken down into 4 discrete tasks illustrated below. Central to Work Package 3 is the use of Quonops©, an anthropic noise prediction system developed by Quiet Oceans that delivers a range of services, including geo-referenced mapping of statistical, historical or real-time human, environmental and biological data; noise pollution according to given ocean-meteorological and human scenarios; noise pollution maps according to dynamic real-time data acquired in-situ and static environmental data; noise nuisance levels maps according to biological species (integration of the M-weighting function and ceilings from Southall et al. (2007); and noise impact assessment such as harm, masking, and displacement.



Work Package 4: Feasibility study for observation network

This work-package will focus on exploring the feasibility on establishing a number of noise monitoring stations within Irish EEZ waters. It is likely that shipping channels will be used as monitoring stations and a reference station would also be identified. The use of one or a series of hydrophones, by nature, will only give local and temporally distinct knowledge. The coupling of direct measurements with modelling performed by Quonops is proposed as a solution to overcome this. The representativeness of noise assessment will be estimated from the output of WP3 to provide guidance on how data should be recorded in the future.


Work Package 5: Communication and Dissemination

The activities and deliverables of this work package will ensure that as wide an audience as possible is made aware of the development of the project, and of its value as an information resource. This will involve disseminating information (informed by and working in close cooperation with WP2-WP4) to range of end-users through design and implementation of a dedicated project website, outreach events and a dedicated project workshop. Publication of outputs in a relevant peer reviewed journal, and presentation of results at an international conference, will ensure wide dissemination to a scientific audience.
