9496-25-DTM - Site Survey of Dogger Bank Tranche C Offshore Wind Farm Area by Gardline Geosurvey Ltd
Gardline Geosurvey Limited was contracted to survey the Dogger Bank Offshore Wind Farm (OWF) Area between 04-Apr-2013 and 02-Aug-2013, comprising the Tranche C zonal surveys. The aim of the surveys was to carry out a geophysical investigation that would broadly assess the entire developable area of the zone. Seabed information was required to inform the site selection process and enable preliminary foundation design to be undertaken. The geological data acquisition programme was carried out on M.V. Sea Surveyor, which sailed from Hull and returned to Blyth, and M.V. Vigilant which sailed from, and returned to, Great Yarmouth upon completion of survey operations.

- Description of processed data sources
-
The bathymetric survey data from both vessels were acquired using Kongsberg Simrad EM710 multibeam echo-sounders, one per vessel. A transducer frequency range of 70-100 kHz was used on the M.V. Sea Surveyor, whereas a 95 kHz transducer frequency was used on the M.V. Vigilant. The EM710 achieved an angular coverage of 68deg/68deg with 400 beams on both vessels.
- Description of data processing
-
Data were processed by Gardline Geosurvey Limited using Caris HIPS and SIPS software (v7.1). A 25m resolution DTM file was produced and made available to the British Oceanographic Data Centre (BODC). The 25m DTM file was then converted by BODC using Globe software (v1.18.18) to the EMODnet Bathymetry standard DTM.NC format at 3.75 arc seconds resolution.
