The primary aim of this benthic survey in the inner region of Loch Ailort, run by SNH for SNH on the 27th April 2017 using the SNH RIB Aphrodite, was to assess the distribution and condition of serpulid aggregations PMF. Quantitative drop-down camera sampling undertaken at 9 stations was used to collect this data. Through the analysis of seabed video, the images were used to describe the nature of the seabed in terms of the physical structure and the species assemblages. Runs and run segments were assessed for the presence of PMFs, as well as for the occurrence and distribution of species and habitats of recognised conservation importance. Spot dives were also undertaken on this survey at 18 locations. This data is yet to be analysed and reported.
