Metadata: Abundance and Biomass of infaunal species from grab samples from a benthic assessment for Fair Head tidal energy development site (Fair Head, Co. Antrim), 2014
Abstract:
This dataset contains information on infaunal abundance and biomass from sediment grab samples and video tows carried out off the coast of Fair Head (Co. Antrim) on the FPV Banrion Uladh (now Queen of Ulster). This survey was carried out to provide a benthic baseline for a potential offshore windfarm development site in May 2014. The main aim of this survey was to undertake a baseline assessment of the species and biotopes found in the area of interest. The survey comprised of 26 video stations and 10 grab stations (3 repeats per station) with 24 samples retained for infaunal analysis- the abundance and biomass was recorded. Particle size analysis (PSA) was also carried out but due to low success rate of grab samples, only 4 samples were appropriate for this analysis.

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | This dataset contains information on infaunal abundance, biomass and associated habitat biotope from sediment grabs and video tows carried out off the North Antirm coast. This survey was carried out as a baseline survey of the benthos in an area that had been proposed as an offshore windfarm. The survey area contained the proposed tidal site and potential routes for cables, 1 leading from the tidal site to Ballycastle (historic route) or leading to Drumnakill Point (northern edge of Murlough Bay) The analysis of this dataset also addressed the conservation important of the benthic communities identified along with their potential sensitivity to certain physical factors by referring to the Northern Ireland Priority Species List as well as information from the Marine Life Information Network for Britain and Ireland (MarLIN). The methodologies for both the video tows and grab samples are detailed below. Video survey and Analysis â?¢ The video system used in this survey was an Osprey camera attached to an epibenthic sledge which was also fitted with a Go-Pro camera. This provided a field of view of 1m2 (oblique) for video analysis. â?¢ The epibenthic sledge was chosen over the drop frame camera as it is a more stable platform for camera footage, especially in stronger currents (current speeds can reach up to 3ms-1 at the survey site). The sledge was towed between the sites as they were relatively close together and to optimise efficiency. â?¢ A GPS overlay was recorded on the osprey to allow the position on the seabed to be estimates. Notes were taken of the ships position as well. â?¢ Due to site hydrodynamics, the video footage had poor visibility and was much faster than ideal. Epifauna of 3cm and larger were identified. Biotopes were classified according to the UK MNCR classification. Benthic grabs and analysis â?¢ To obtain sediment samples for infaunal analysis both a pipe dredge and a day grab were used in attempt to obtain more sediment. â?¢ A 0.1m2 day grab was used to take a sample of the sediment and associated infaunal communities. â?¢ When the sample reaches the deck, a 250ml sample is taken for PSA and a further 25ml is taken for C and N analysis. The rest of the sample is carefully sieved to reveal any infauna. â?¢ Fixed Formalin (4 percent buffered formaldehyde) is added to the remains of the sample and these are placed in labelled buckets. â?¢ The samples are sent to accredited taxonomic laboratories were they are identified to as high a level as possible and weighed. â?¢ Due to the presence of large cobbles in many regions the jaws became blocked of the day grab which meant that a large amount of sediment was lost by the time the grab reached the ship. â?¢ Only 4 sediment PSA were retained for analysis and 24 samples were retained for infaunal analysis (abundance and biomass data). |
