2018 JNCC/CEFAS Farnes East Marine Conservation Zone Monitoring Survey CEND0618 RV Cefas Endeavour dataset https://portal.medin.org.uk/portal/start.php?tpc=010_2a308ec3-aba7-4e72-8330-1f52e402d2bf Joint Nature Conservation Committee (JNCC) and Centre for Environment, Fisheries and Aquaculture Science (CEFAS) undertook a dedicated monitoring survey of the Farnes East (FRNE) Marine Conservation Zones (MCZ) between 23 April and 4 May 2018 aboard the Research Vessel (RV) CEFAS Endeavour. North East of Farnes Deep (NEFD) MCZ was also surveyed. Farnes East MCZ is a joint inshore and offshore site located off the northeast of England, approximately 11 km from the Northumberland coast. The site has a total area of 945 km2 and ranges in depth from 30 m to 100 m. The site was designated due to the composition of the seabed, which predominantly comprises subtidal sediments with small patches of moderate energy circalittoral rock. Additionally, the site was designated for the presence of the ‘Sea-pen and burrowing megafauna communities’ (SPBMC) habitat Feature of Conservation Importance (FOCI) in the southeast corner of the site (a section of the Farne Deeps trench), and the presence of the species FOCI ocean quahog (Arctica islandica). The aim of the survey was to acquire sentinel (Type 1) monitoring data to contribute to the development of a monitoring time-series for the Farnes East MCZ. The two main objectives of the survey were: 1) to further characterise and map the extent of the SPBMC habitat FOCI feature, which was under-represented in previously acquired data and consequently not well defined, and 2) to acquire quantitative data to enable sentinel (Type 1) monitoring of the designated Broadscale Habitat (BSH) features ‘Subtidal coarse sediment’, ‘Subtidal sand’, ‘Subtidal mud’, and ‘Subtidal mixed sediments’. The survey collected mini Hamon grab samples and seabed imagery using camera sledge. 20261019
