The survey included the collection of multibeam bathymetry, sidescan sonar and magnetometer data throughout the proposed wave hub site and cable route. The primary objective of the survey was to provide data for archaeological analysis by a third party contracted by the client. The survey was carried out using the vessel FPV Morven between 28th August and 20th September, 2008. The equipment used included a Geometrics G882 marine magnetometer, a fully motion-aided Reson 8101 multibeam system and an Edgetech 4200 dual frequency sidescan sonar system. A Coda Octopus F180 motion reference unit with EGNOS differential corrections was used for horizontal positioning of the vessel. Tides were acquired using a Leica GX1230 system and post-processed with RINEX data. Survey lines were run at 50 m spacing with the sidescan and magnetometer systems deployed off the port and starboard sides respectively. The Reson 8101 swath transducer head was attached by a pole to the port side of the vessel throughout. Forty-one approximately northsouth lines were run in the main proposed wave hub area, with a further 11 lines run along the cable corridor. Cross lines were also completed inshore to ensure sufficient coverage was acquired.
