Metadata: 2013, EMU Ltd, Dogger Bank Offshore Wind Farm (Tranche A, Cable Route and Nearshore), Benthic Ecology Characterisation Survey
Abstract:
The survey of the Dogger Bank Tranche A area and the associated export cable corridor was undertaken by Gardline Environmental Limited (Gardline) between 07/05/2011 and 30/01/2012. The specific objective of the project was to provide characterisation of benthic ecological conditions specific to the site within the Dogger Bank Offshore Wind Farm Zone (hereafter referred to as the Dogger Bank Zone) to inform the associated Environmental Impact Assessments (EIAs) for projects located within this Tranche. This report and associated data fulfils this objective through characterisation of the benthic ecological conditions. However, no characterisation employing geophysical data has been undertaken, with this report detailing results up to and including a statistical interpretation of the data. Biotope classification has been undertaken, taking into account the results of both geophysical survey and the ground truthing, via grab samples and drop down camera work reported in this document (see Envision, 2012). The approach to survey design and sample location is described in Envision (2012). Details of survey methods and the field report have been completed by Gardline and are reported separately.

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | Environmental seabed images were obtained using a Kongsberg 14-208 digital stills camera system with a dedicated strobe and video lamps, mounted within a stainless steel frame. An Ultra-short Baseline (USBL) positioning beacon was attached to the freshwater lens camera frame. Footage was viewed in real time via an umbilical, assisting in the control of the digital stills camera allowing for shot selection if a sediment change or feature was observed. A minimum of five seabed photographs were taken at each station using hover and drift technique, separated by a time gap of at least 10 seconds. The scale bar represents 1cm intervals. Benthic faunal and sediment samples were recovered using a modified, galvanised steel 0.1 m2 Mini Hamon grab with a stainless steel bucket, constructed by Gardline. Methods used adhered to industry standard guidelines for benthic studies (Ware & Kenny 2011). Sediment chemistry samples were recovered using a modified, stainless-steel 0.1 m2 Day grab constructed by Gardline. The grab carried extra weights to induce better penetration on impact and an extended bucket lip to reduce sediment washout. Storm feet and elastic straps were used to reduce the likelihood of the instrument pre-triggering in the water column during deployment. PSD analysis was undertaken at EMU’s UKAS accredited sediment laboratory using in house methods based on BS1377: Parts 1 – 3: 1990 (dry sieving), and BS13320: 2009 (laser diffraction). The latter method was used when the fine fraction of sediment (<63 µm) comprised >5% of the total sample by weight. Samples for contaminants analyses were sub-contracted to an experienced UKAS accredited chemistry laboratory. All tests were undertaken to relevant standards, and results certificates are provided as part of Appendix VII. The macrofaunal analysis was undertaken at EMU’s marine laboratories. |
