2014 Scottish Natural Heritage (SNH) biological analyses of Scottish Environment Protection Agency (SEPA) Loch Linnhe benthic camera survey

This SNH analyses of underwater video footage collected in Loch Linnhe is intended to improve knowledge of the occurrence and distribution of the species and habitats of recognised conservation importance and help to improve future nature conservation action by undertaking a marine habitat classification using JNCC standards, and to search for Priority Marine Features (PMF). A drop-down video survey to collect this benthic habitat data was undertaken by SEPA between the 23rd and 28th May 2014 on board the SEPA survey vessel Sir John Murray. The underwater video footage was collected using a high definition underwater camera system, custom built for the purposes of environmental monitoring by marine Scotland Science and SNH specifically for use on SEPA's survey vessel, at 81 stations. The seabed video and still photographic imagery material was collected as part of SEPA's work to gauge the health and ecological condition of coastal water bodies but passed to SNH to be analysed by a contractor to describe the nature of the seabed in terms of the physical structure and the species assemblages. Video runs and run segments were assessed for the presence of protected features and other priority marine features (PMFs), as well as for the presence of species and habitats of recognised conservation importance.本数据集为苏格兰自然遗产（Scottish Natural Heritage, SNH）针对林赫湾（Loch Linnhe）采集的水下视频素材开展的分析项目，旨在提升学界对具有公认保护价值的物种及栖息地的分布与发生情况的认知；同时通过采用联合自然保护委员会（Joint Nature Conservation Committee, JNCC）标准开展海洋栖息地分类，并搜寻优先海洋特征（Priority Marine Features, PMF），助力优化未来的自然保护行动。2014年5月23日至28日，苏格兰环境保护局（Scottish Environment Protection Agency, SEPA）在其科考船“约翰·默里爵士号”（Sir John Murray）上开展了下放式底栖栖息地数据采集水下视频调查。本次水下视频素材由苏格兰海洋科学协会（Marine Scotland Science）与SNH专为SEPA科考船环境监测需求定制的高清水下摄像系统采集，共布设81个采样站位。该海底视频与静态摄影影像资料原本作为SEPA评估沿海水体健康与生态状况工作的一部分采集，后移交至SNH，由承包商依据物理结构与物种群落特征对海底环境的属性进行描述分析。研究人员对视频航段及其子片段进行了评估，以确认其中是否存在保护地物、其他优先海洋特征（PMFs），以及具有公认保护价值的物种与栖息地。
