The images will be analysed qualitatively and catalogued to provide a basis for comparison with similar images obtained following deployment of the device to assess possible damage to the benthic boundary layer. The survey may conveniently be considered to encompass two components: cable route to shore and EVOPOD device and mooring.

Benthic flora and fauna will be identified to ascertain the concentration of species across the mooring area. The same will be done for video footage and stills take along the path of the power and communication cable, with appropriate discretisation of the data according to the water depth and distance from the shore. Particular care will be taken to identify and highlight any rare and/or vulnerable species. A follow-up survey will be perfomed within12 months of device installation to assess the impact on the benthic zone of Evopod and its mooring system. This survey will combine targeted inspection of the regions where the mooring makes contact with the seabed, and will quantitaviely address the change in species-concentration by comparison with the pre-installation records.
