Underwater video observation was done by Latvian Institute of Aquatic Ecology. Open data policy.

Species abundance and seagrass cover. Calculated from photo quadrats and video recorded by divers along seabed transects surveyed by divers as part of GENIALG monitoring surveys. Seaweed farm located in Ventry Harbour, Co. Kerry (Ireland). The samples were collected at seven different time points along the growing season in 2018 and 2019. Samples collected as part of the GENIALG project (project ID: 727892, GENIALG - GENetic diversity exploitation for Innovative Macro-ALGal biorefinery, http://genialgproject.eu/). GENIALG was funded by the European Union Horizon2020 programme. The remit of the work was assessing the environmental footprint and ecosystem services provided by seaweed aquaculture in Europe to provide best practice advice to industry.

The Institute of Estuarine and Coastal Studies (IECS) was commissioned by Forewind Ltd to carry out a Phase 1 biotope survey of the intertidal zone located between the towns of Redcar and Marske-by-the-Sea, Tees estuary, Teesside. This area has been identified as a preferred landfall location for export cables, with the ultimate aim of connecting offshore wind farms off the Teesside coastline to the National Grid. The intertidal survey was completed as part of the development of the Environmental Impact Assessment (EIA) required from Forewind Ltd to continue with the proposal to use this area as a landfall site.

In the Mediterranean deep-sea two scleractinian species, Lophelia pertusa (= Desmophyllum pertusum) and Madrepora oculata, make up the dominant structure-forming corals. The Lacaze-Duthiers canyon is the only French Mediterranean canyon where the two species L. pertusa and M. oculata have been observed living together in large quantities, the situation generally described for the biocoenosis of cold-water corals (CWC). In this canyon large colonies (more than 40 cm) of both species of scleractinians were observed at depths ranging from 246 m to 541 m at the head of the canyon and its western flank. The second canyon is the Cassidaigne canyon, where M. oculata seems to be the only structure-forming scleractinian there. The largest concentration of M. oculata colonies was observed on the west flank of the canyon along a crest at depths ranging from 200 to 210 m. Mature M. oculata colonies attained heights up to 40 cm. M. oculata were observed in three other canyons: Bourcart, Sicié and Var. In the Bourcart canyon, M. oculata was observed on a shelf of hard substratum at 331 m depth. Several single branches protruded from a slab. In the Sicié canyon a 15-cm colony of M. oculata was observed at 255 m depth, while in the Var canyon, three young branches 2 cm long were seen growing at 350 m depth on a wall of hard rock.

Benthos samples taken as part of the EIA of the harbour constructions at Rotterdam

" This dataset focuses on the development of soft bottom fauna, 10 years after the putting into use of the PAWP, and therewith 10 years of exclusion of fisheries in the wind park area. This investigation is part of WOZEP (a Dutch Governmental Offshore Wind Ecological Program), which is a five-year research program to investigate the gaps in knowledge concerning the ecological effects of off-shore wind energy.
