Metadata: 2007 Scottish Natural Heritage (SNH) Isle of May rocky reefs site condition monitoring survey
Abstract:
The purpose of benthic survey around the Isle of May was to initiate site condition monitoring (SCM) of the littoral and sublittoral reef feature of the Isle of May SAC. The SCM survey was undertaken with the objectives to: establish a baseline biological data set that will facilitate the assessment of the favourable conditional status of the reefs in future; and to allow SNH to form judgement on the current condition of the reefs in light of existing SAC management measures. To fulfil these objectives an extensive drop-down video survey of the sublittoral reef habitats of the SAC at 60 sites to characterise the major reef biotopes and MNCR phase 2 surveys of reef biotopes along relocatable transects at 5 sites spanning both littoral and inshore sublittoral environments.

This seabed data from the Isle of May was collected by Heriot-Watt University for SNH between the the 28th August and 5th September 2007. Video images were obtained from 60 drop-down video drift tows, each approximately 3 min duration, onboard the vessel Thistle B II on the 28th August. The video system used consisted of a Panasonic NV-GS150 3 chip digital video camera within a Seapro housing held within a frame and illuminated by twin 100 watt lamps. A 100 m umbilical cable carried the video signal to a Sony Video Walkman for real-time observation and for recording. At each station the camera was deployed briefly from a drifting vessel, noting the times, depths and precise positions at the start and end of the drift using differential GPS (dGPS). SNH contracted Heriot-Watt University 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. Stations were also categorised as reef, non-reef or mixed habitats based on the presence of reef biotopes or a mixture of reef and non-reef biotopes. Reef biotopes were regarded as those falling under the higher biotope categories of Infralittoral Rock and Circalittoral Rock. Relocatable survey transects were established at 5 sites, chosen to represent the range of environmental conditions and biotopes found on intertidal and shallow subtidal reefs of the SAC. The position of the marker was fixed by dGPS and several photographs taken of it from different viewpoints, with the position of the camera recorded by dGPS and the bearing to the marker taken with a sight-bearing compass. The transect was split up into a series of zones which were defined in terms of differences in the composition of the biological community and or by changes in substrate type. All subtidal work was carried out with the use of SCUBA. A band 2 m either side of the tape was surveyed by two workers intertidally and two workers subtidally. Within each zone records were taken of substrate type and biota using the MNCR SACFOR scale of abundance, with collection of material for laboratory examination where in situ identification was not possible. Subtidally, a digital video camera (Panasonic DX100B in a Seapro housing) and a digital still camera (Canon 400D digital SLR with 17 mm wide-angle lens and Sea and Sea housing) were used to make representative visual recordings of the transect zones. Intertidally, the same video camera was used to record the zones, but the digital still camera was a KODAK DX6490. Where practicable, on the intertidal and subtidal components of each transect a zone of specific interest was selected for quantitative analysis. Within such zones a 10 m tape was laid perpendicular to the transect line, with the distance along the line (and the depth for subtidal zones) being recorded. 10 square, non-overlapping quadrats were placed randomly along the tape, using a set of random numbers and both sides of the tape. On the shore a quadrat of area 0.25 m2 was employed, whereas subtidally quadrats were 0.1 m2. Before examination each quadrat was photographed using a Canon 400D digital SLR and 17 mm wide-angle lens subtidally and a Kodak DX6490 intertidally. The biota within each quadrat was then enumerated using either counts or percentage cover estimates as appropriate. |
