Benthic infaunal abundance and biomass from Belfast Lough dredge disposal monitoring operations 2017 and 2018

OBIS UK MeasurementOrFact Open in mapper Explore occurrences

This dataset contains information on benthic infaunal abundance & biomass from sediment grabs off the Copeland Islands in Belfast Lough in late 2017 and early 2018 on the RV Corystes. This survey was carried out to describe the species and seabed habitats within a 0.5NM buffer zone of a dredge disposal site. The survey was carried out pre operation to allow the potential impacts to be investigated. Particle size analysis (PSA) and Carbon & Nitrogen analysis were also carried out on the sediments from the grab samples. All grab samples contained fauna species and sediment classification was carried out on all samples. This dataset also contains information on the SACFOR abundance and associated infaunal habitat in Belfast Lough in late 2017 and early 2018 as part of the post operation survey. This survey was carried out on the RV Corystes using a dropframe fitted with HD video camera, halogen lights, strip and point lazers for scaling, USBL, GoPro.
