(LWP) (a wholly owned subsidiary of Aquamarine Power Ltd.) is seeking to develop a wave energy demonstration array off the west coast of the Isle of Lewis. As a first stage of the Environmental Impact Assessment (EIA) for the project, LWP commissioned Royal Haskoning Ltd. to produce an Environmental Scoping Report (Lewis Wave Power Ltd., 2011) to facilitate the identification and assessment of the potential environmental impacts associated with the project. The survey reported on here formed this field-based benthic component. Its purpose was to provide site-specific benthic data to inform an assessment of impact of the proposed development. The key objectives were to: - Determine the distribution and abundance of marine habitats and communities within the study areas; - Determine the substrate type at all locations sampled; - Identify habitats or species of conservation importance.

Sampling began on 24th August at the north end of the original Siadar study area, working southwards from one transect to the next. Video drops were carried out along the transects from east to west with the prevailing wind and current conditions. On Day 2 (25th August) the field work began at the southern boundary of the Labost site, moving north, again working with the wind (which had moved round to southerly - Force 2), and surface currents. After a change of survey plans in accordance with Aquamarine’s instructions, Envision concentrated on completing and extending the northern (Siadar) site. However, by the end of Saturday 27th August, the whole of both the Labost and Siadar survey areas and four additional transects, adjoining the northern boundary of the Siadar site, had been completed. Fortunately, the sea conditions had remained favourable during this time, although sea work ceased at around 3.15pm on Saturday 27th as the wind had moved round to the NW, Force 5, and was due to pick up to Force 7-8 later. Conditions were not suitable to go to sea on Sunday 28th (NW Force 7-8). Interestingly, the underwater visibility was relatively good on the first survey day (7m+), but it subsequently became poor (approximately only about 2m), due to a sharp rise in the presence of phytoplankton The Crown Estate +44 020 7851 5000 enquiries@thecrownestate.co.uk pointOfContact EPSG Geodetic Parameter Registry 2021-03-18 revision OSGB36 / British National Grid
