Title

2011 Scottish Natural Heritage (SNH) biological analyses of Marine Scotland (MS) Sound of Sleat, Loch Hourn and Loch Nevis benthic camera survey

Abstract

The purpose of this benthic survey in the Sound of Sleat and the outer basins of Loch Hourn and Loch Nevis was to improve knowledge of the occurrence and distribution of species and habitats of recognised conservation importance, particularly priority marine features (PMFs). An underwater video and still photograph survey was conducted by SNH for MS on the 15th and 16th June 2011 to collect detailed biological information on the seabed species and habitat features present. Drop-down video drift tows were undertaken at 35 sites in the area. The images, analysed under SNH contract by Dr Colin Moore, were used to describe the nature of the seabed in terms of the physical structure and the species assemblages. SNH used the SEPA vessel SV Sir John Murray for this survey - footage was collected from the Sound of Canna on the same cruise.

Lineage

This subtidal seabed data from the Sound of Sleat, Loch Hourn and Loch Nevis was collected by SNH between the 15th and 16th June 2011 onboard the vessel SV Sir John Murray. Video images were obtained from 35 drop-down video drift tows deployed just above the seabed. Stills were taken using a video frame grab system on this survey. Positional, time and depth data are available for the start and end of video runs, with positions also available every one minute for this survey. Analyses of the video footage was undertaken by Dr Colin Moore, contracted by SNH, to describe the physical structure and species assemblages present. Based on the physical and biological attributes, biotopes were allocated. 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 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.
