Metadata: 2015 Scottish Natural Heritage (SNH) Sound of Barra benthic camera and grab survey (July)
Abstract:
Benthic habitat survey in the Sound of Barra, run by Aquatic Survey and Monitoring Ltd (ASML) for SNH onboard the MV Spray, undertaken between the 21st and 26th July 2015. The primary aim of this survey was to improve knowledge of the occurrence and distribution of species and habitats of recognised conservation importance within the designated Special Area of Conservation (SAC). The survey also contributes to site condition monitoring of the SAC and to a programme of refining the distribution of Habitats Directive Annex 1 habitats. Drop-down video drifts were undertaken at 128 stations (22nd-26th). The video and still imagery was used to describe the nature of the seabed in terms of the physical structure and the species assemblages. The presence of priority marine features (PMFs) was recorded for all video samples. Grab sampling was also undertaken on this survey at 14 stations (21st-22nd) within the SAC. The grab survey was designed to target examples of both the mearl and Zostera marine biotopes with the aim to inform management of the SAC sediment biotopes.

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | Observation of the seabed was carried out at 128 sites within the Sound of Barra SAC from the vessel, MV Spray. At each site a dropdown video system was deployed just above the seabed for drifts of a few minutes. The imagery 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 SACFOR scale. Based on the physical and biological attributes, biotopes were allocated using the 2004 Marine Habitat Classification for Britain and Ireland (version 04.05). Where video runs traversed different habitats, the run was split into the corresponding segments, each of which was labelled as a separate video sample. DDV were recorded on SD at a resolution of 720x576. No video overlay was available for this survey, however positional and depth details are provided for the start and end of the runs. All video footage analyses were undertaken by SNH contractor Dr Colin Moore. The macrobenthic survey was carried in the SAC during the same time period in areas of maerl and seagrass habitat. Sediment sampling at 14 stations was undertaken using a 0.1m2 stainless steel Day grab. At each station 2 grab samples were collected as biological replicates and processed for infaunal analysis. Each grab sample sediment was washed and collected over a 1mm sieve mesh, retaining the residue for fixation with buffered 10-20% formalin solution. Additionally at each station a further grab sample was collected for the purpose of PSD of the surface sediments. All infaunal analyses were undertaken by SNH contractor ASML. |
