This programme will be known as the Galloper Wind Farm (GWF). The survey was undertaken under Airtricity Contract Reference '09.0558.G' 'Benthic & Geophysical Survey Services for the Environmental Impact Assessment (EIA)' and was substantially completed during the period 3r d August to 5t h December 2009, at which point the GWF survey was postponed due to prolonged periods of severe weather. The surveys were eventually completed during the period 16th February to 14th March 2010.

These were undertaken in order to provide: 1) Full multi-beam bathymetry coverage of the areas; 2) A classification of the seabed sediments for the refinement of a detailed benthic survey; 3) Information on the shallow geology of the study area and to map any variations in thickness and mobile sediment cover; 4) An identification and location of any existing artefacts or obstructions within the study area, i.e. cables, pipelines, wrecks, trawler marks, etc; 5) Information on areas of the survey site, where the seabed has steep sided features; 6) Soil stratigraphic sections - summarising the range of inferred ground conditions for preliminary foundation design; and 7) Maps and charts, including track plots, bathymetric charts, seabed features with sonar and magnetic contacts and isopachyte charts to significant reflectors, including recent sediments.
