This dataset contains information on infaunal abundance & biomass from sediment grab samples and video tows carried out off the coast of Fair Head (Co. Antrim) on the FPV Banríon 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 & 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 & 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. The most abundant infauna found was Ascidiacea.
This data set comprises of marine epibenthos (74 identified taxa derived from Algae, Annelida, Arthropoda, Bryozoa, Chordata, Cnidaria, Echinodermata, Mollusca, Nemertea, Porifera) data quantified in June 2009 at The Wave Hub development zone, a Marine Renewable Energy Installation (MREI) in Hayle, Cornwall, South West UK. The Wave Hub development zone is compartmentalised into four areas, five sites were surveyed in each area using a high definition towed underwater video system. At each site a 200 x 0.5 metre transect of the seabed was undertaken. The survey was carried out as a baseline to characterise the seabed fauna present, prior to any subsea infrastructure being deployed at the test site. The design was also replicated to the east and west of the Wave Hub site to provide controls for future impact assessment.
This data set comprises of marine epibenthos (approx. 74 identified taxa derived from Algae, Annelida, Arthropoda, Bryozoa, Chordata, Cnidaria, Echinodermata, Mollusca, Porifera) data collected during September 2010 from the Big Russel channel in Guernsey, Channel Islands, UK. Surveys were appointed as part of a Regional Environmental Assessment to determine the feasibility of marine renewable energy developments in the area. Data were collected using a high definition towed underwater video system. 36 transects each approximately 200 x 0.5 metres were undertaken to document the epibenthos in the Big Russel, providing a baseline of species composition in an area where tidal development may occur and to identifying suitable control areas for future impact assessments.
