Survey completed by Gardline Environmental on behalf of Forewind Ltd, 17-Nov-2011 to 17-Jan-2012. One of the objectives of the survey was to investigate pre-selected sites for the presence or absence of Annex I habitats protected under the European Habitats Directive using appropriate guidance notes and high resolution under water video and stills photography (Fresh Water Lens System). Footage was viewed in real time via an umbilical, assisting in the control of the digital stills camera. This allowed for shot selection, in the event that the system recorded a sediment change or feature at the seafloor. Video footage was recorded directly onto VHS video and DVD, and labelled with the relevant job details, write-protected and stored. completed T van Steen Gardline Geosurvey Limited Environmental Report Writer +44 (0)1493 845 600 +44 (0)1493 852 106 Endeavour House, Admiralty Road Great Yarmouth Norfolk NR30 3NG United Kingdom geosurvey@gardline.com http://www.gardlinemarinesciences.com/page/gardline-geosurvey/ originator Phil Redstone Forewind Ltd GIS & Data Manager +44 (0)800 975 5636 Davidson House, Forbury Square Reading RG1 3EU United Kingdom info@forewind.co.uk http://www.forewind.co.uk/ custodian asNeeded dataset bup Gardline_Forewind_8975_Videos_2012 Habitat characterisation SeaDataNet Parameter Discovery Vocabulary 2012-03-03 revision 73 Hydrocarbons SeaDataNet Agreed Parameter Groups 2011-07-28 revision 21 Sediments Global Change Master Directory Science Keyword variables 2007-04-18 revision 4 Seabed photography SeaDataNet Parameter Discovery Vocabulary 2012-03-03 revision 73 Seabedsurvey sediment distribution MEDIN Data Guidelines 2012-05-01 revision 3 Macrofauna Global Change Master Directory Science Keyword variables 2007-04-18 revision 4 total organic carbon Marisaurus Thesaurus 2010-09-22 revision 28 particle size distribution Marisaurus Thesaurus 2010-09-22 revision 28 Video survey MEDIN Data Guidelines 2012-05-01 revision 3 Marine Environmental Data and Information Network Feasibility The Crown Estate Renewable Energy Development Phases 2012-05-15 revision 1 Consenting The Crown Estate Renewable Energy Development Phases 2012-05-15 revision 1 Zone search area The Crown Estate Renewable Energy Development Areas 2012-05-15 revision 1 Not to be used for navigation copyright copyright other restrictions Copyright Forewind Ltd 0 eng utf8 geoscientificInformation oceans 0.1163 1.6988 54.1148 54.9048 2011-11-17 2012-01-17 http://www.marinedataexchange.co.uk/search?q=#fq=fq%3DProject%253Amde1r3z3db888 download https://www.marinedataexchange.co.uk/details/2514/summary A link to the web service or dataset. https://www.marinedataexchange.co.uk A link to the general host site. dataset This data was collected during the Forewind Ltd, DOGGER BANK TRANCHE A NEARSHORE CORRIDOR BENTHIC SURVEY by Gardline Geosurvey Ltd. The object of the survey was to investigate pre-selected sites for the presence or absence of Annex I habitats protected under the European Habitats Directive using appropriate guidance notes and high resolution under water video and stills photography (Fresh Water Lens System), to delineate the extent of any Annex I habitat found, also ground truthing of selected sites using a sediment sampler for the determination of Herring Spawning Ground (HSG) potential based on guidelines provided by Cefas (2001). Survey also undertakes characterisation of seabed sediments and Archaeological assessment. In order to accomplish above objectives Fresh Water Lens Camera System was used to record videos of seabed features. Footage was viewed in real time via an umbilical, assisting in the control of the digital stills camera. This allowed for shot selection, in the event that the system recorded a sediment change or feature at the seafloor. Video footage was recorded directly onto VHS video and DVD, and labelled with the relevant job details, write-protected and stored. At the end of the survey all of therecords were delivered to Gardline’s Great Yarmouth office for sorting, checking and either storage or re-delivery to their respective analytical subcontractors. Equipment Details: Manufacturer - Konsberg/Simrad. Model - OE14-208 Pixels - 5.0 M Standard Lens - f 7.2 – 28.8 (35mm format equivalent to 38 – 140mm) Focus Control - Automatic or manual 50mm to infinity Trigger - Remote from deck Height Control - USBL Beacon and Video footage Video Overlay - Oceantools VO1 Field of View - 47.8 (deg H) by 36.2 (deg V) Lighting - 1 strobe, 2 video lamp Result: Seabed Imagery and videos: 33 Stations were successfully investigated. However, investigations at Station NS34 failed on two occasions due to bad visibility resulting in poor quality seabed imagery.
