The aim of the survey was to collect grab samples that will provide baseline data on the benthic ecology and sediment composition within the OWF area. Additionally the survey was to utilise Drop Down Video (DDV) to determine the presence of potential cobble reef Annex 1 habitats (EC Habitats Directive) the OfTW cable export corridor and investigate sites of potential archaeological importance within both the OWF area and export route. Two transects (running N-S and E-W) were completed at 10 potential cobble reef sites and one potential pockmark feature. For each transect still images were taken every 15 seconds. One image from each minute of the transects was analysed for faunal and floral abundance. This dataset presents results of analysis of those images.

For cobble reef transects the freshwater lens was not used and the camera was mounted At an oblique angle. All video was recorded simultaneously to a laptop and internal memory card. Scaling lasers and a video overlay was used to provide positional and station information. Stills were taken at 15 second intervals and then one image from each minute of the transect was analysed for floral and faunal abundance.
