An underwater video survey were conducted by CEFAS for SNH on the 30-31st August 2012 to collect detailed biological information on the seabed species and habitat features present. Drop-down video drift tows were undertaken at 29 sites. Analyses on the seabed video and still photographic imagery, commissioned by SNH, were used to describe the nature of the seabed in terms of the physical structure and the species assemblages. CEFAS used the vessel NLV Pole Star for this survey.

Video images were obtained from 5 drop-down video drift tows onboard the vessel NLV Pole Star. JNCC likely commissioned CEFAS to undertake an offshore survey but in the event of bad weather contingency inshore sampling location were provided to CEFAS by SNH. The drop-down video camera set up also carried a vertically-orientated digital stills camera which took photographs of the seabed at approximately 1 minute intervals and a laser scaling system to aid biotope determinations. Continuous positional information is available via a video overlay system, however only the start and end depths of tows are available for this cruise. No HD footage was recorded on this survey. SNH contracted Dr Colin Moore to analyse the video footage to describe the physical structure and species assemblages present. Species present were identified and quantified using the semi-quantitative MNCR SACFOR scale, as far as possible. Where video runs traversed a sequence of biotopes, the runs are split into corresponding segments with the transition points recorded using time. Segmentation of runs was not practicable in the case of mosaics of recurring biotopes, in which case all biotopes observed were simply listed. Runs and run segments were assessed for the presence of PPFs and other PMFs, as well as for the presence of species and habitats of recognised conservation importance according to a number of additional criteria, including citation on the following lists: the IUCN Red List of Threatened Species (lower risk category), the OSPAR List of Threatened and/or Declining Species and Habitats and the Scottish Biodiversity List.
