It includes two main elements of work: an improved assessment of sediment grain size and an improved assessment and quantification of sediment transport. A refined description of sediment gradings data has been established at strategically selected site across the proposed wind farm site, at adjacent sites across Gunfleet Sands and at sites along the Clacton Frontage. The analysis of sediment gradings now includes a more rigours description of grain size variation, with consideration of modal classes. Potential changes in sediment mobility at these sites have been assessed for both tidal and wave regimes. For the tidal regime, small effects are determined locally on Gunfleet Sands, but not along the foreshore. Based on this assessment, there is unlikely to be any long-term changes in the sediment transport regime either at any of the sites considered. There will however be significant short-term changes resulting from local scour around each of the turbine support structures which has not been addressed by this study.

ABPmer completed all agreed sediment grab sampling over a period of 2 days, on the 19 and 26 October 2004, using the survey vessel MV Arie Dirk operating out of Burnham. A 0.1m² Day Grab was used to collect all grab samples, and to provide consistency to the sampling method provided for previous benthic surveys (Titan Surveys, 2002a). During survey operations each sample was recorded against its planned sample location, approximate water depth (read from off echo-sounder), date and time of recovery, initial visual description and relative volume of material recovered. On occasions when the volume of any sample was deemed insufficient then up to two further attempts were made at each location, noting that it is not always possible to recover material efficiently off a hard substrate.
