2010 Scottish Natural Heritage (SNH) biological analyses of Marine Scotland Science (MSS) Crowlin Islands seabed camera survey

The purpose of this benthic survey south of the Crowlin Islands was to improve knowledge of the occurrence and distribution of species and habitats of recognised conservation importance, particularly priority marine features (PMFs), and to ground-truth multibeam data. An underwater video and still photograph survey was conducted by MSS for MSS on the 21st of May 2010 to collect detailed biological information on the seabed species and habitat features present. Drop-down video drift tows were undertaken at 3 sites in the area. The images, analysed under SNH contract by Dr Colin Moore, were used to describe the nature of the seabed in terms of the physical structure and the species assemblages.本项克劳林群岛以南海域的底栖生物调查，旨在深化对具有公认保护价值的物种与栖息地（尤其是优先海洋保护地（priority marine features, PMFs））的出现情况与分布格局的认知，并完成多波束测深数据的地面验证。2010年5月21日，由MSS开展水下视频与静态摄影调查，以采集研究区域内现存海底物种与栖息地特征的详细生物学数据。本次调查在该区域的3个站点实施了下放式视频漂流拖曳作业。所获影像由科林·摩尔博士依据SNH的委托合同开展分析，用于从物理结构与物种组合两方面描述海底环境的特征属性。
