Infaunal SACFOR abundance data from underwater video footage from selected Special Areas of Conservation (SACs), Northern Ireland, 2017.

This dataset contains information on the SACFOR abundance of benthic infauna species from video footage from Skerries & Causeway Special Areas of Conservation (SAC) 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. This survey took place on 2017-09-25 to 2017-09-27 on board the RV Corystes. A towed sledge camera was used in this survey. The video sledge was attached by a 400m cable with a USBL system, scaling lasers and an ancillary GoPro. A 0.1m2 day grab was also used as further ground-truthing but this information is not included in this dataset. Particle size analysis and Carbon & Nitrogen analysis were also carried out (not included in this dataset). Information on the substrate was collected and is included in this dataset.
