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

The purpose of this benthic survey off North Westray 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 10th of September 2010 to collect detailed biological information on the seabed species and habitat features present. Drop-down video drift tows were undertaken at 1 site in an area of rapid currents in Westray Firth. 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.

本次西北雷岛附近底栖调查的目的是提升对已识别的具有保护意义的物种和栖息地分布的认知，尤其是优先级海洋特征（PMFs），并对多波束数据进行实地验证。由MSS代表MSS于2010年9月10日进行了一次水下视频和静态摄影调查，以收集关于海底物种和栖息地特征的详细生物信息。在西雷伊特湾流速迅速的区域，对1个地点进行了降落式视频拖曳作业。由科林·摩尔博士在SNH合同下进行分析的图像，被用于描述海底的性质，包括其物理结构和物种群聚。
