This dataset contains information on the SACFOR abundance of benthic infauna species from video footage from selected Special Areas of Conservation (SAC’s) in Northern Irish waters. The selected SAC’s have previous multibeam data available for each site, therefore this project was to provide ground-truthing evidence for these habitats. The surveys took place from 2017-09-25 to 2017-09-27 on board the RV Corystes and the selected SAC’s are as follows; Red Bay SAC, The Maidens SAC and Skerries & Causeway SAC.
