Infaunal SACFOR abundance data from underwater video footage from the Skerries and Causeway Special Area of Conservation (SAC), Northern Ireland, 2017.
This dataset contains information on the SACFOR abundance of benthic infauna species from video footage from Skerries and Causeway Special Areas of Conservation (SAC) in Northern Irish waters. The selected SACâs 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 2017-09-27 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 and Nitrogen analysis were also carried out (not included in this dataset). Information on the substrate was collected and is included in this dataset.

The Skerries and Causeway SAC survey took place on board the RV Corystes on 2017-09-27 using the sledge camera. There were 3 sledge tows carried out initially but the ancillary GoPro flooded on the 2nd tow and the sledge became entangled with a fishing creel on the 3rd tow (this was successfully untangled by the crew). A 4th tow was then carried out to the eastern side of the Skerries and Causeway SAC. It is important to note that on 2017-09-27 there were rough sea conditions which may have an effect on the quality of the video. This was mitigated to the best of our ability by using two experienced marine biologists to review and analyse the video data.
