    "name": "2009 EMU Limited, Wave Hub Hydrographyc Survey for Archaeological Assessment",
    "description": "Emu Ltd was commissioned by Halcrow Group Limited to undertake a hydrographic survey\r\nof the proposed wave hub site, located approximately 18 km from St Ives, Cornwall. The\r\nsurvey included the collection of multibeam bathymetry, sidescan sonar and magnetometer\r\ndata throughout the proposed wave hub site and cable route. The primary objective of the\r\nsurvey was to provide data for archaeological analysis by a third party contracted by the\r\nclient.\r\nThe survey was carried out using the vessel FPV Morven between 28th August and 20th\r\nSeptember, 2008. The equipment used included a Geometrics G882 marine magnetometer, a\r\nfully motion-aided Reson 8101 multibeam system and an Edgetech 4200 dual frequency\r\nsidescan sonar system. A Coda Octopus F180 motion reference unit with EGNOS differential\r\ncorrections was used for horizontal positioning of the vessel. Tides were acquired using a\r\nLeica GX1230 system and post-processed with RINEX data.\r\nSurvey lines were run at 50 m spacing with the sidescan and magnetometer systems deployed\r\noff the port and starboard sides respectively. The Reson 8101 swath transducer head was\r\nattached by a pole to the port side of the vessel throughout. Forty-one approximately northsouth\r\nlines were run in the main proposed wave hub area, with a further 11 lines run along the\r\ncable corridor. Cross lines were also completed inshore to ensure sufficient coverage was\r\nacquired.",
