Natural England (NE) Condition Assessment Monitoring for Reefs, Isles of Scilly European Marine Site - Diving Survey June 2011 dataset https://portal.medin.org.uk/portal/start.php?tpc=010_9c5e8b413bd429c0417be394655630aa Monitoring studies on subtidal reef within the Isles of Scilly SAC were initiated during nine days of diving fieldwork in June 2011. A team of six divers undertook a total of 62 person-dives at 13 sites, spread between the north coast of St Martinâ??s to the south coast of St Agnes. A total of six attributes (assigned to the four sub-features of the â??reefâ?? feature: kelp forest communities; vertical rock; subtidal rock and boulder communities; and subtidal faunal turf communities) were considered and a monitoring strategy for each was devised (referred to as â??tasksâ??). All six tasks were undertaken, with baseline monitoring data being acquired for all. All sites were recorded with video, including a number of recorded quadrats and transect positions. dGPS positions and accurate depth measurements of all sites were taken which, together with site diagrams, should provide sufficient information for biotope relocation in future visits. 20121022 20121022
