The purpose of this benthic survey (cruise 0713S) west of Islay was to improve knowledge of the occurrence and distribution of species and habitats of recognised conservation importance, particularly priority marine features (PMFs), because the area is one of a number of proposed renewable energy locations. An underwater video survey were conducted by MSS for MSS between the 21st June and 3rd July 2013 to collect detailed biological information on the seabed species and habitat features present. Drop-down video drift tows were undertaken at 39 sites. Analyses on the images, commissioned by SNH, were used to describe the nature of the seabed in terms of the physical structure and the species assemblages. MSS used the vessel FRV Scotia for this survey.

This subtidal seabed data from west of Islay was collected by MSS between the 21st June and 3rd July 2013. Video images were obtained from 39 drop-down video drift tows onboard the vessel FRV Scotia. The drop-down video camera set up also carried a vertically-orientated digital stills camera which took photographs of the seabed at intervals and a laser scaling system to aid biotope determinations. Track and depth data were displayed on a video overlay system on the SD camera feed. 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.
