Emu Limited was commissioned by NEG Micon UK Ltd. to perform hydrographic surveys of the turbine locations and cable routes in order to determine this. This report describes the pre-construction debris survey, commissioned to determine the current seabed conditions at the site. This is a baseline data set for comparison with data collected during the post-construction survey. The survey vessel Midnight Express was used to conduct the work over the windfarm site between 6th - 11th August 2004. Data were collected over the entire windfarm site, including turbine locations, cable routes and area around the meteorological mast. A single-beam echosounder was used to determine seabed levels across the site for the production of a colour contour plot. Any seabed anomalies have been identified on the seabed features chart.

There was a good correlation between the seabed features identified on the sidescan sonar data with the single beam bathymetry collected over the area. The data collected during this survey period will be used for comparison to data collected immediately post-construction. https://www.marinedataexchange.co.uk/details/807/summary A link to the web service or dataset. https://www.marinedataexchange.co.uk A link to the general host site.
