The main objectives were to assess detailed bathymetry, seabed features and shallow soil conditions for input to turbine foundation planning across the site. The survey was carried out in 2 phases; 1st phase incorporated the acquisition of bathymetry, side scan sonar and sub-bottom profiler data; 2nd phase incorporating the acquisition of 2D ultra high resolution (UHR) seismic data only. A Geo-Resources GeoSpark 200 sparker sub-bottom profiling system was used during phase 1 of the survey. 2D UHR seismic data was acquired is a 2.1kJ sparker source, together with a 24 channel streamer. For 1st phase analogue work, the SV Chartwell vessel was equipped with mulitbeam and single beam echo sounders, side scan sonar, sub-bottom profiler and magnetometer systems. Survey operations were commended on 7th April, 1st phase completed on 5th May 2010. 2nd phase UHR seismic data acquisition commenced on 10th May 2010 and was completed on 21st May 2010. Seabed levels range from 35.1m below LAT, close to the south western corner of the development area, to 68.1m below LAT at the extreme north west corner. The results of the Side Scan Sonar indicate that, in general, grandular sediments are present at seabed level across most of the survey area. These deposits are interpreted as ranging from shelly medium to coarse grained sands to medium to coarse grained sands and gravels, with occasional cobbles and boulders. A total of 110 targers were picked from the development area, most of which appear to be isolated large boulders (with a maximum dimension generally >1m). A number of targets are associated with the 'Jacky' infrastructure. The processed sub-bottom profiling data are presented as a series of Isopachyte Charts. The sparker data was mainly utilised for the interpretation of the marine sediments above the seabed multiple, with UHR data mainly below the seabed multiple. The deliverables of the survey were presented as a series of reports and raw and processed data.

Objectives were to assess detailed bathymetry, seabed features and shallow soil conditions for input to turbine foundation planning across the site. Water levels reduced to LAT (Lowest Astronomical Tide). The tide gauge was deployed on 3rd April 2010 at 505447mE, 6449377mN (UTM30, WGS 84), approximately 300m south-east of the Beatrice site southeast boundary, in water depths approximately 40m below LAT. Calibrations were completed and survey operations were commenced on 7th April, following a period of adverse weather. The first phase analogue work was completed on 5th May 2010. The tide gauge was recovered and the vessel was then remobilised in preparation for the second phase 2D UHR seismic data acquisition. The mobilisation period was extended due to equipment non compatibility problems. Second phase 2D UHR seismic data acquisition commenced on 10th May 2010 and was briefly interrupted on the 14th May, by a change of seismic source to a more powerful and lower frequency sparker sub-bottom profiler system. Following a spell of good weather, the second phase digital seismic work was completed on 21st May and the vessel was subsequently demobilised.
