Metadata: 2017-2019 Scottish Natural Heritage (SNH) Loch Creran subtidal SCM survey
Abstract:
The programme of studies was carried out from 7th May 2017 to 28th January 2019 principally by diving along transects and at essentially point stations, as well as by dropdown video. Video data collected during this survey and previous surveys in 2005 and 2014 has been used to assess development of the features over time. The aims of this study were to carry out site condition monitoring of the biogenic sub-features of the loch in order to identify any deterioration in the condition of the features and to form a judgement on their current condition and to assess the current condition of the flame shell bed feature.

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | The condition of the serpulid reef habitat in the lower basin of Loch Creran was assessed by diver along 40 transects over the period 13/06/2017 to 28/01/2019. Two transect configurations were employed. At 15 sites measures of reef condition were obtained along two parallel 20 m long transects 10 m apart (termed 'paired transects'). The locations of these sites were chosen to provide good coverage of historically rich serpulid habitat and in some cases to groundtruth 2015 sidescan imagery. To avoid inter-worker variability, all reef condition surveys were undertaken by the same experienced surveyor, who was accompanied by a videographer recording the condition of the habitat within the same area. The same reef condition data and video footage were also obtained along ten relocatable 25m long transects established for the Didemnum vexillum monitoring study in the lower basin of the loch. On 13-15 June 2017 the degree of reef development was measured in situ by diver for replicates of all substrate types at all five locations. The distribution of the flame shell bed habitat was examined along 23 diver transects in the vicinity of South Shian and Creagan Narrows during the period 2017 - 2019. The drift dive survey was supplemented by grab sampling at three sites on 8th September 2017; A single 0.1 m2 van Veen grab sample was taken at each site and the number of Limaria hians retained on a 1 mm sieve counted. A modiolus distribution dive survey was carried out in August 2018. At each site a shot line was dropped at the chosen position and a diver assessed Modiolus SACFOR density along a short 3 - 5 minute swim eastwards. The dropdown video survey was undertaken in September 2018. The video system used consisted of an SD Panasonic NV-GS150 3 chip digital video camera within a Seapro housing held within a frame and illuminated by twin 100 watt lamps. The frame also carried an HD GoPro video camera. Modiolus SACFOR abundance, substrate type and biotope were recorded from analysis of the video footage. |
