2015 SSE Renewables Beatrice Offshore Wind Farm pre-construction drop down video survey

A pre-construction benthic characterisation survey was conducted by APEM Ltd at the proposed Beatrice Offshore Wind Farm (OWF) and Annex 1 Habitat Survey of the Offshore Transmission Works (OfTW) cable corridor (APEM ref 413984, client ref ED518) between the 22nd and the 27th June 2015.
The aim of the survey was to collect grab samples that will provide baseline data on the benthic ecology and sediment composition within the OWF area. Additionally the survey was to utilise Drop Down Video (DDV) to determine the presence of potential cobble reef Annex 1 habitats (EC Habitats Directive) the OfTW cable export corridor and investigate sites of potential archaeological importance within both the OWF area and export route. Two transects (running N-S and E-W) were completed at 10 potential cobble reef sites and one potential pockmark feature. For each transect still images were taken every 15 seconds. One image from each minute of the transects was analysed for faunal and floral abundance. This dataset presents results of analysis of those images.

由APEM有限公司于2015年6月22日至27日对拟建的贝翠丝海上风电场（OWF）及附件1的海洋输电工程（OfTW）电缆走廊栖息地调查（APEM参考编号413984，客户参考编号ED518）进行的施工前底栖特征描述调查。此次调查旨在收集样本，以提供关于OWF区域内底栖生态和沉积物组成的基线数据。此外，调查还旨在利用下拉视频（DDV）技术确定潜在卵石礁附件1栖息地（欧洲共同体栖息地指令）的存在、海洋输电工程电缆输出走廊以及探讨OWF区域和输出路线内潜在的考古学重要性地点。在10个潜在卵石礁地点及一个潜在凹坑特征处完成了两条测量线（分别为北-南和东-西走向）。对于每条测量线，每15秒拍摄一张静态图像。分析每分钟内的一条图像，以确定动物和植物群的丰富度。本数据集展示了这些图像分析结果。
