Metadata: 2010-2014, CMACS, Zone 9 Celtic Array, Benthic, Fish and Intertidal Surveys
Abstract:
This study forms chapters (9 & 10) of the Stage 2 Preliminary Environmental Information (Stage 2 PEI) of the Rhiannon Offshore Wind Farm, which is part of the Environmental Impact Assessment (EIA). The study was carried out by CMACS - Centre for Marine & Coastal Studies and it describes the existing environment with regards to Benthic Ecology and Fish and Shellfish Ecology and assesses the potential impacts of the Offshore Development area of the proposed Rhiannon Wind Farm (RWF) on the Benthic and Fish ecology. The assessment describes and focuses on the impacts on relevant receptors associated with the Offshore Development of Rhiannon Wind Farm (RWF), which extends seaward from Mean High Water Springs (MHWS) seaward (including any potential impacts in the intertidal area). This consists of the Wind Farm Site and Export Cable Area (ECA – which is the area within which sub-sea export cables will bring power from the Wind farm site to shore at a number of potential Cable Landfall Sites along the north Anglesey coastline). The Wind Farm Site includes all wind turbines, intra-array cables, and ancillary structures such as substations and convertor stations. The Potential cumulative impacts between the Offshore and Onshore developments was also assessed.

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | Baseline data methodology Benthic Ecology Seabed communities from site specific surveys were described in accordance to the biotope classification published by Connor et al. (2004) wherever possible. The main classification levels of relevance to this study are the “biotope” and “the biotope complex”. Some published information that is based on the European Nature Information System (EUNIS) classification were also used. The primary data source for the seabed habitats and benthic communities of the Irish Sea zone was from the dedicated survey carried out in the summer of 2010 and based on circa 6 months of detailed acoustic survey (including sidescan and multibeam surveys) which was groundtruthed during August and September 2010 by an extensive series of camera (stills and video) and Day grab surveys. Dedicated 4m beam trawl surveys carried out in autumn 2010 (November) and spring 2011 from a commercial fishing vessel using commercial gear, and primarily targeting commercial fish species, were also able to provide some additional information on the main epibenthos. Considerable data from other sources was also used to extend knowledge outside of the Irish Sea Zone boundary. Baseline information on the Rhiannon Wind Farm was supplemented by an additional site specific survey carried out from 29th October to 30th November 2012 Intertidal Data from series of intertidal benthic surveys of the intertidal zone of the northern Anglesey coastline carried out between 1996 and 2004 by the Countryside Council for Wales (CCW) were used and in conjunction with information from further Phase I methodology site-specific surveys. Intertidal surveys at the five potential cable landfall sites within the Export Cable Area was completed in June 2013, they were completed during a period of spring tides at or around low water (ranging between 0.6m and 1.0m) to maximize the exposure of the lower shore areas. Surveys were completed on foot, Mapping and the sampling protocols followed the standard methodology described in Wyn et al. (2002) and JNCC (2010). Field notes, photographs, waypoints and boundaries were then used to identify biotopes present with reference to Connor et al. (2004). Updated biotope maps were produced for each cable landfall option using the most recent 04.05 classification (Connor et al. 2004). Fish and Shellfish Ecology Baseline information has been compiled during the various stages of the processes including the ZAP, scoping and PEI stages and through consultation. Data was collated from site-specific beam trawl surveys using 4m beam trawl, as part of the baseline survey programme within the Irish Sea Round 3 Zone (ISZ). Information from the ZAP surveys were reviewed along with the long term data sets from the Cefas ground fish surveys. Additional information were also obtained from Department of Agriculture and Rural Development (NI) relating to the trawls and egg surveys they complete throughout the Irish Sea. Information from Welsh Assembly Government (WAG) and the ‘Sea Fishing Atlas of Wales’ were reviewed and information on migratory species and their stock status in the Irish Sea was collated from the Environment Agency (EA). Spawning and nursery ground information was collated from Coull et al. (1998) and Ellis et al. (2012). Information on commercial fish and shellfish stocks was informed from Chapter 13 of the Stage 2 PEI : Commercial Fisheries which used MMO and ICES landings data to inform the Assessment. Desk based study of available literature on these species was also done. Please note: Chapter 7 Physical processes and Chapter 10 Fish ecology (includes shellfish) within the Stage 2 PEI are closely linked to benthic ecology study. Also Inter-relationships exist with a number of other Chapters of the Stage 2 PEI and these are summarized in more detail later (see 9.425 of the report). Some relevant appendices should be read in conjunction with this report such as • Appendix 9.1 Rhiannon Wind Farm benthic survey 2012. • Appendix 9.2 Seastar Surveys (2013). Geophysical and environmental survey export cable area. Phase 2 – Volume 2. Environmental report revision 1 Final report 5th July 2013. • Appendix 9.3 Benthic ecology example sublittoral seabed photographs • Appendix 9.4 Report of an intertidal survey of potential cable landings off the North Anglesey coast. Report to Celtic Array Ltd. CMACS Ltd (2013a). Also chapters Chapter 9 – Benthic Ecology; Chapter 11 – Marine Mammals, sea turtles and basking shark; and Chapter 13 – Commercial Fisheries within the Stage 2 PEI are closely linked to Fish and Shellfish Ecology |
