The four other mounds, labelled Mound C to F are located within the Lincs wind farm at turbines LD61, LS62, LS43 and LS44 respectively and were created in during 2009. The aim of the survey was to assess the size of the mounds, the sediment characteristics and the epifaunal communities within the vicinity of the mounds. During October 2011, high resolution multibeam bathymetry for was acquired around each mound. Grab samples and drop down video/still photography were sampled on the centre of each mound and additionally at locations 50 metres north, south, east and west of the central location. Having acquired and provisionally processed the datasets, the sample location of Mound A was observed to not be centred on the mound. It was decided that further benthic sampling in the form of grab samples at Mound A was required and was carried out in November 2011. This affects Lincs, Lynn and Inner Dowsing.
