Site survey of Dogger Bank Tranche A development area by GEMS Survey Ltd

GEMS Survey Ltd. (GEMS) were contracted by Forewind Limited to undertake a bathymetric and geophysical survey of the Tranche A development area and two met mast locations (which were later revised) within the Dogger Bank Zone, in addition to a cable reconnaissance from Tranche A to the Yorkshire coastline. The primary objectives of the survey were to produce sufficiently high resolution bathymetric and geophysical data and interpretations to allow regional interpretation for planning and modelling purposes; for met mast design to commence and to provide high quality data to inform further benthic and environmental surveys. This survey was carried out between 8 July 2010 and 26 December 2010. The vertical datum for this project is LAT using predicted tides. This metadata relates to the bathymetric datasets. The surveys were undertaken onboard the MV Aquarius and MV Kommandor Jack.

Statement
Description of data processing : This bathymetric data was collected using SEA SWATHplus and R2 Sonic 2024 systems and processed using QINSy and Fledermaus. It was delivered to Forewind in the following formats. XYZ (.xyz), Flederrmaus (.sd), TIFF (.tif), Google Earth (.kmz), ASCII (.asc), ArcGIS (.shp). A 5m DTM file was prodiced and made available to the British Oceanographic Data Centre (BODC). The 5m DTM file was then converted by BODC using Globe software (v2.5.2) to the EMODnet Bathymetry standard DTM.NC format at 25m resolution.
Description
Description of processed data sources : The bathymetric survey data from both vessels were acquired using using SEA SWATHplus (177Hz) and R2 Sonic 2024 systems.
