Description

This project was conducted by Emu Ltd at the site of the proposed Westermost Rough offshore wind farm and cable corridor. The scope of the survey specified the collection of simultaneous multibeam bathymetry and sidescan sonar along survey lines to ensure full coverage of the wind farm site and a 600m wide corridor on the proposed northern cable route. A small ground truthing survey, consisted of 27 grabs across the wind farm site and cable corridor, was used to aid seabed interpretation. A combination of singlebeam bathymetric data and topographic data extended the survey from the landward limit of the multibeam survey to as far inland as the steep cliff face at the back of the beach, and at the same width as the cable corridor . The primary objective of the survey was to determine water depths, seabed bathymetry, surficial sediment types and seabed features to inform locations for a benthic and geotechnical survey and further wind farm developments. The survey was conducted between the 17th October and 28th November 2008. Data were collected using an Edgetech 4200 sidescan sonar and a fully motion aided Reson 8101 multibeam system. A Knusden 320M singlebeam echosounder aboard the vessel Calypso was used to collect singlebeam bathymetry data on the 25th February 2009. The topographic survey was carried out using Leica 1200 RTK GPS system on the 12th and 13th December 2008.
