A subset of these features (termed MPA search features) will drive the identification of Nature Conservation MPAs. The principal aim of the present investigation was to improve knowledge of the occurrence and distribution of species and habitats of recognised conservation importance in Scottish waters, especially PMFs, but also taking into consideration other importance measures. This was to be achieved through the analysis of seabed video and still photographic imagery collected during research cruises around Scotland carried out by various organisations between 2000 and 2012. This record is for ROV survey data of habitats in Loch Torridon and the adjacent region of the Inner Sound.

Scottish Natural Heritage Commissioned Report No. 536 (Project no. 13879). Database Marine Recorder Documents Published report Geographic Information System shapefiles dataset Commission Regulation (EU) No 1089/2010 of 23 November 2010 implementing Directive 2007/2/EC of the European Parliament and of the Council as regards interoperability of spatial data sets and services 2010-12-08 publication Survey details are given in Table 1, which also provides the system of site identification codes employed in this report. Video images were obtained from ROV runs, dropdown video drifts or a towed sledge. For the Orkney and Loch Eriboll surveys the camera frame also carried a digital stills camera, which took vertically-orientated photographs of the seabed at intervals, and a laser scaling system. Track and depth data were provided, except for the Loch Torridon ROV runs, where only the start positions and depths were recorded, with subsequent depth data available from sporadic use of a video overlay system. All depths were converted to depth below chart datum, employing TotalTide software (Admiralty, Taunton) to determine tidal rise at the most appropriate secondary port. The images were used to describe the nature of the seabed, in terms of the physical structure and the species assemblages. Species present were, as far as possible, identified and quantified using the semi-quantitative MNCR SACFOR scale (Hiscock, 1996). Based on the physical and biological attributes, biotopes were allocated (Connor et al., 2004). Runs traversing a sequence of biotopes were split into corresponding segments, with the transition points recorded using the 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 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: Species of Conservation Concern (UK Biodiversity Steering Group,1995), IUCN Red List of Threatened Species (lower risk category) (IUCN, 2011), OSPAR List of Threatened and/or Declining Species and Habitats (OSPAR, 2008), UK Biodiversity Action Plan Priority Species (UKBAP, 2007) and Scottish Biodiversity List (SNH, 2010). Species SACFOR data, habitat descriptions, biotopes, depth and positional data have been incorporated into the Marine Recorder repository.
