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.本项于克劳林群岛以南海域开展的底栖生物调查，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））的出现规律与分布格局的认知，并完成多波束数据的实地验证。2010年5月21日，MSS受自身委托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信息。本次调查在该区域的3个站位实施了下放式视频漂移拖曳作业。经SNH委托，科林·摩尔博士对所获影像进行分析，据此从物理结构与物种群落两个维度刻画了该海域海底的本质特征。
