2018 Scottish Natural Heritage (SNH) Sound of Barra benthic camera survey

The primary aim of this benthic survey in the Sound of Barra, run by SNH and Marine Scotland Science (MSS) between 9th - 12th June 2018 using MSS vessel MRV Alba na Mara (cruise 0818A), was to refine the distribution of biotopes including Annex 1 habitats within and out with the SAC boundary using quantitative drop-down camera and grab sampling. Dropdown video drifts were undertaken at 32 stations, largely along the eastern fringe of the Sound. Through the analysis of seabed video, the images were used to describe the nature of the seabed in terms of the physical structure and the species assemblages. Runs and run segments were assessed for the presence of protected features and other PMFs, as well as for the presence of species and habitats of recognised conservation importance. Grab sampling was also undertaken on this survey at 77 sites. This data is yet to be analysed and reported.

本次由苏格兰自然遗产保护局（SNH）和苏格兰海洋科学（MSS）于2018年6月9日至12日联合执行的巴罗海峡底部调查，旨在利用MSS的MRV Alba na Mara船（航次编号0818A）所配备的定量式下潜相机和抓取采样技术，对生物群落，包括附则I所规定的生境在内的SAC边界内外的分布进行精细化。在巴罗海峡东部边缘附近共32个站点进行了下潜视频漂移实验。通过对海底视频的分析，图像被用来描述海底的性质，包括其物理结构和物种群落。对河流及其段落进行了评估，以确定保护特征和其他重要生态特征的存在，以及对公认具有保护意义的物种和生境的存在。此外，在此次调查中，还于77个地点进行了抓取采样。目前，这些数据尚未进行分析和报告。
