ABSTRACT

Wave Hub is a Marine Renewable Energy Installation (MREI) off the southwest peninsular of the UK. Wave Hub's seabed infrastructure, including the main connection unit and 18 km of seabed cable were deployed in 2010. This study assesses the species assemblages present within the Wave Hub development zone in the context of the ecological processes they contribute to local ecosystems. To enhance knowledge on the potential future impacts of MREI the effect of the power cable was quantified, with its associated 80,000 tonnes of rock armoring. Species assemblages were compared between rock armored and control sites two years after installation.
