Metadata: 2014 Scottish Natural Heritage (SNH) Sound of Arisaig site condition monitoring survey
Abstract:
The principal purpose of the study was to carry out site condition monitoring of the Sound of Arisaig SAC, in order to identify any deterioration in the condition of the subtidal sandbank feature and to form a judgement on its current condition. The approach taken to achieve this aim was to perform an extensive drop-down video survey and a grab survey of the component habitats of the feature, together with more detailed surveying of the habitat at selected maerl bed sites. A further aim of the work was to validate the presence of the MPA search feature 'inshore deep mud with burrowing heart urchins' which has been reported close to the SAC. This investigation was carried out by means of drop down video, grab and dredge surveys in muddy areas within the SAC and in adjacent regions, including sites of historical records of the habitat.

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | As part of the Site Condition Monitoring survey of inshore sediments of the Sound of Arisaig, biotope distribution was examined chiefly by dropdown video survey from the vessel RV Serpula. At each station the camera was deployed from a drifting vessel for around 2 - 3 minutes, noting the times, depths and precise positions at the start and end of the drift using dGPS. Video runs were very short as only the initial biotope recorded was needed, in order to compare with the biotope recorded at the same location during the 2003 baseline site condition monitoring survey. At a small number of sites where navigation was difficult, the dropdown system was replaced by diver-held video. 34 of the 150 randomly positioned video sites that formed the basis of the baseline survey are now referred to reef biotopes (and so would not contribute to assessment of a reduction in extent or condition of the designated feature), therefore in addition to the 116 random sites allocated to sediment biotopes, 21 of the non-random sedimentary habitat sites from the baseline survey were also selected for resampling. The condition of representative sediment biotopes was also examined by single 0.1 sq m van Veen grab samples taken for infaunal analysis at 20 sites from RV Serpula, with 150 ml subsamples taken for particle size analysis. The infauna was screened with a 1 mm mesh sieve. The condition of maerl habitats at five sites was examined by diver using MNCR phase 2 survey methodology along a 25 m transect, width 2 m either side of the tape was surveyed by two divers, with collections of four core samples for analysis of associated biota. To supplement the real-time visual records and collections, the transect band was videoed using a hand-held digital video camera and photographs taken of the maerl and associated community using two digital still cameras. Four replicate core samples were taken in areas of living maerl using a 10.3 cm diameter corer to a depth of 20 cm. An additional 20 cm sediment core of 5 cm diameter was taken for particle size analysis. In addition to the derivation of an overall estimate of live and dead maerl percentage cover along the transect, carried out during the MNCR phase 2 surveying, live and dead maerl cover within the transect band was also assessed using diver estimates of percentage cover within random 0.25 m2 quadrats. Validation of the presence of the inshore deep mud biotope, SS.SMu.CFiMu.BlyrAchi, was achieved by a dropdown video survey from RV Serpula of muddy sediments within the SAC and in adjacent regions, particularly in Loch nan Uamh ( 18 sites), and the upper section of Loch Ailort (7 sites). This was supplemented by 3-5 van Veen grabs at 12 promising sites and their contents sieved on a 0.7 cm mesh. Single quantitative grab samples were also taken at four of these sites in order to determine the condition of likely examples of the habitat and to better characterise it. Subsamples from these grabs were taken for particle size analysis and the fauna extracted and analysed. Naturalist dredge sampling at 5 most promising sites was used to determine the presence of burrowing heart urchins. |
