Description

The EIA process for an offshore wind farm requires a full understanding of the marine
ecology of the area which may be affected. This requires a full review of existing benthic
survey data (marine ecology desk study) as well as benthic surveys of the wind farm site,
cable routes and adjacent areas. For this site, surveying the offshore environment involved
benthic grab sampling and epibenthic trawl surveys, as well as drop down video surveys on
rocky ground where grab/trawling was not possible. Intertidal biotope mapping was also
undertaken along the cable route.
These baseline surveys were necessary for the characterisation of the marine communities in
the vicinity of the cable route and wind farm site, and to identify the location of any Annex 1
habitats (under the Habitats Directive) present. Comparison of these results with postconstruction
monitoring will allow an assessment of any changes that may occur after
installation of the facility.
