This was done in conjunction with the completion of an earlier hydrographic and geophysical survey across the whole of the development area, which had to be postponed due to severe weather during the original survey period (September to November 2006). High-resolution side scan sonar, swath multi-beam and single beam bathymetry data were acquired along all survey lines, which were run at 100m centres, in order to accurately map the entire seabed within the wind farm development area. Additional lines were run at 25m offsets from the turbine positions, in order to provide detailed information around the turbine/seabed interface. Data acquisition took place during the period 4th April to 13th April 2007, with survey works undertaken using the survey vessel MV ‘Freja’.

These survey lines formed a grid system running NNE-SSW and NW-SE providing four lines of data in differing directions around each turbine monopile. Data acquisition took place during the period 4th April to 13th April 2007, with survey works undertaken using the survey vessel MV ‘Freja’. The primary objective of the survey was to map the bathymetry within a series of nine 100m x 100m boxes, centred at selected turbine locations, thereby providing a detailed scour assessment. The nine locations were chosen based on an analysis of the 2006 survey data, specifically to include all of the different sediment types that can be found on the seabed across the development area. All positions are expressed as WGS’84; UTM Zone 30N coordinates, throughout this report. https://www.marinedataexchange.co.uk/details/49/summary A link to the web service or dataset. https://www.marinedataexchange.co.uk A link to the general host site.
