The survey was undertaken to meet Wave Hub’s preconstruction obligations under the Food & Environmental Protection Act (FEPA) (1985), to acquire information as part of a wider survey campaign, and to make suggestions to establish a programme of environmental monitoring. An interim survey report was presented in June 2010 outlining field data acquisition methods used during the Wave Hub survey together with preliminary field observations derived from grab sampling and seabed video. It was recommended that a post construction survey be undertaken at a 1 year interval, at a similar time of year to that of the previous survey, undertaken in 2010. This should have resulted in a survey being undertaken between June and August 2011 but due to a lack of suitable weather windows, the survey was finally undertaken in November 2011. However the survey was undertaken before any major changes in sea temperature had occurred and as such, no particular effects of the survey delay on data acquisition or quality of data was noted.

The stations were a duplication of the 2010 pre-construction survey (EMU 2010), with the addition of two stations recommended on the cable route that appeared under-represented within the survey. The additional sites were duplications of two sites undertaken in previous surveys by Fugro Survey Ltd and Precision Marine Ltd. Incorporation of the additional stations resulted in seven stations along the cable route (three mid-cable route and four inshore), four within the development area and two to the west of the main Wave Hub area. This section presents the survey and data collection methods used.
