Previous surveys have been conducted at 6 monthly intervals from September 2010.\r\n\r\nThe surveys are required for the FEPA Licence Numbers: Gunfleet Sands I & II (GF1L/2011/0064/9 & GF2 L/2011/00065/3) Offshore Windfarm.\r\n\r\nThe scope of work, for the March 2012 survey, was as undertaken in 2010 which included:\r\n1. MBES and SSS survey of 100m wide corridor along Export Cable Route between the windfarm substation and landfall site, to the east of Clacton-on-Sea.\r\n2. For 2011, a requirement for additional works and analysis identified by DONG Energy, namely: - difference surface along export line, and comments on wider area geomorphology and bathymetric changes.\r\n3. For August 2011 the scour around the substation was assessed and compared against previous surveys.\r\n4. For March 2012 there was a requirement to delineate the full extent of scour from the substation.\r\n\r\nThis series covers survey elements which were undertaken on the 23rd and 24th March 2012 along the Export Cable Route and around the substation.\r\n\r\nThe survey work was carried out using the PLA survey vessel \u2018Yantlet\u2019, with bathymetric data being collected using a hull-mounted Reson SeaBat 8125h MBES and SSS extracted from the bathymetric data in the form of snippets and backscatter.", "includedInDataCatalog": { "@id":
