Benthic surveys were undertaken by Emu Ltd on board the survey vessel Discovery. The main survey took place from 15 ‐ 19 of April 2011 and sampled 59 stations in and around the Project area. EMU used grabs (0.1m2 Day, 0.1m2 Hamon, 0.04m2 Shipek as appropriate to conditions) to collect sediment for analysis (of benthic invertebrates, particle size, total organic carbon, and contaminants), and drop‐down photography to record habitats and visible epifauna at each station. In addition, the drop‐down photography survey investigated 6 transects that were tentatively identified from the geophysical survey as potentially being reefs formed by the honeycomb worm Sabellaria spinulosa. However, the survey did not record any Sabellaria reef structures within the Project area. At the request of the MMO a further survey was conducted on 10 and 11 July 2011 at 17 stations using a 2m scientific beam trawl to collect epifauna (fauna either attached to, or living on, the seabed surface).
