This dataset contains information on infaunal abundance & biomass from sediment grabs in Belfast Lough as part of a larger & ongoing habitat mapping project. The sediment & infaunal survey was carried out in January 2018 by AFBI and this dataset was integrated into the larger mapping project since 2012. The project is joint with the British Geological Society and Belfast Harbour with the aim of mapping the seabed floor and updating it from more historical information. The seabed mapping was carried out on the White Ribbon vessel (British Geological society) using Kongsberg EM3002D multibeam and on the FPV BanrĂ­on Uladh using the same multibeam system. The benthic sampling in 2018 (this dataset) was carried out on board the RV Corystes using a day grab. Particle size analysis (PSA) was carried out and the infaunal samples were sent away to accredited taxonomic laboratories to be indentified. The most abundant species recorded was the echinoderm Amphiura filiformis and the most frequently recorded (present in all samples) was the hydrozoan sertulariidae.
