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 16t h February to 14t h 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.
