This report presents the survey results and analysis of the pre-construction phase. The purpose of the survey was to:- \u2022 Identify the occurrence of Sabellaria spinulosa and, if present, describe the extent of development of reef communities likely to be of conservation importance; \u2022 Identify of other benthic habitats that might be sensitive to the construction and operation of wind farms; \u2022 Provide a baseline from which the effects of construction can be assessed, especially on any Sabellaria spinulosa; \u2022 Survey the seabed bathymetry. The survey strategy stipulated that grab sampling was to be avoided where reefs were detected. No substantial reef structures were detected on the sidescan sonar and this permitted a more representative grab sampling program. 30 samples were taken for sediment size and infauna. The infauna were analysed using multivariate techniques and trend analysis in a geographic information system (GIS). The sediments were classed into categories and these used to classify the AGDS data. One of the \u2018sediment\u2019 classes was the biogenic sediment Sabellaria spinulosa tubes. The classification predicted that the location most likely to support Sabellaria spinulosa reef was at the margin of the stony/gravel shoal. Although no substantial Sabellaria spinulosa reefs were found, dense aggregations were observed and the predicted distribution of habitats most likely to support this biogenic habitat, derived from the interpretation of the acoustic data, lay on the eastern margin of the Lynn, Lincs and Inner Dowsing sites. This also coincided with high species diversity. The majority of the shallow gravel shoal which makes up the proposed wind farm sites support low to moderate diversity epifaunal biotopes typical of the southern North Sea and are of low conservation significance when taken in their wider geographic context.", "includedInDataCatalog": { "@id": "http://portal.medin.org.uk/portal/json-ld/catalog.jsonld" }, "conditionsOfAccess": [
