Burbo Offshore Wind Farm is a twenty-five turbine, 90MW development located in Liverpool Bay approximately 6km from the coastlines of Wirral, Crosby and Liverpool. A licence was issued to the wind farm developer, SeaScape Energy Ltd, allowing them to construct and operate the wind farm providing certain conditions are met. The licence (31864/07/0) was issued under the Food and Environment Protection Act (FEPA) and contains specific requirements for surveys of subtidal benthic (seabed) invertebrate ecology and fish. These are in part addressed by an annual 2m scientific beam trawl survey which complements other work, notably grab sampling and 4m (commercial) beam trawl surveys. The 2m beam trawl survey is undertaken by Centre for Marine and Coastal Studies Ltd (CMACS) on behalf of SeaScape. The programme commenced with a baseline (pre-construction) survey in autumn 2005 which built upon surveys undertaken in 2002 in support of the project environmental impact assessment. The report in this series presents the results of monitoring carried out in autumn 2007, after construction of the wind farm, and compares the results with baseline data and the data collected during construction of the wind farm in 2006.
