The task was achieved by comparing the data obtained during the 2007 survey to those of the 2002 baseline study (Emu Ltd, 2002a), the 2005 first post-construction study (Emu Ltd, 2006) and the 2006 second post-construction study (Emu Ltd, 2007). Benthic samples were collected by means of a full sized Hamon Grab sampler, with subsequent analysis for macrofauna and sediment components, and by scientific 2m Beam trawl to provide qualitative data on epibenthos and fish species across the area Fugro EMU Limited marketing@emulimited.com originator The Crown Estate +44 020 7851 5000 1 St James's Market London SW1Y 4AH enquiries@thecrownestate.co.uk custodian notPlanned Documents Marine Environmental Data and Information Network Geology Species distribution GEMET - INSPIRE themes, version 1.0 2008-01-06 revision Sedimentary structure Zoobenthos generic abundance Zoobenthos taxonomy-related counts Zoobenthos taxonomic abundance SeaDataNet P021 parameter discovery vocabulary 2009-11-16 revision Port-Construction monitoring otherRestrictions Publically Available https://www.marinedataexchange.co.uk/content/info/terms-of-use 5 eng biota geoscientificInformation SeaDataNet vertical extent keywords 2010-01-01 revision bathybenthic 1.0271 1.1399 51.3596 51.4768 2007-05-22 2007-05-23 https://www.marinedataexchange.co.uk/details/TCE-3907/summary A link to the web service or dataset. https://www.marinedataexchange.co.uk A link to the general host site. series MEDIN data guideline for fish and benthos data by trawl and dredge 2011-02-02 publication Conformant true Emu Ltd undertook the field Hamon grab and Beam trawl sampling of the benthos and the subsequent laboratory processing of the sediment samples. All methods employed by Emu Ltd conformed to InHouse operating procedures and/or International Standard Organisation (ISO) 9001 control procedures where appropriate and are described below. The sediment particle size distribution analysis was undertaken at Emu Ltds United Kingdom Accreditation Standards (UKAS) accredited laboratory. Taxonomic analysis of the macrofaunal samples obtained by grab and trawl sampling was undertaken by Emu Ltd who are participants in the National Marine Biological Analytical Quality Control Scheme (NMBAQC) scheme. This scheme is an independent, national Quality Control (QC) scheme designed to assess the quality of marine benthic taxonomy between laboratories in the UK. Emu Ltd have participated since 1996 and have consistently achieved 95% compliance with the scheme. The subsequent biomass analysis was completed at Emu Ltds laboratory. The survey design aimed to provide data on the spatial distribution of the benthic faunal communities across the area, in order to allow the comparison of results with the previous study as well as with future surveys at the same locations. This will enable any potential impacts arising from the Wind Farm development scheme at Kentish Flats to be assessed over time. Sample stations were positioned to include the area covered by a single tidal excursion from the boundaries of the development area, in this case up to a distance of approximately 8km to the west and 8km to the east, based on Admiralty Tidal Diamond D, Chart No. 1183. In addition, four reference stations were located approximately 5km north east and south east of the development site, away from potential impacts, in order to provide reference data for the purposes of the long term monitoring.
