2016 Scottish Natural Heritage (SNH) Loch Alsh benthic camera survey

The primary aim of this benthic survey in Loch Alsh, run by SNH and Marine Scotland Science (MSS) for SNH from the 4th - 6th October 2016, was to improve knowledge of the occurrence and distribution of the species and habitats within the Lochs Duich, Long and Alsh Marine Protected Area (MPA). Dropdown video drifts at 16 stations where used to achieve this, using MSS vessel MRV Alba na Mara. This survey also contributed to a monitoring programme (of management effectiveness) of refining the distribution of Habitats Directive Annex 1 features adjacent to the partially overlapping Special Area of Conservation (SAC) and to a study of the distribution of protected features within the MPA. 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.

此次由苏格兰自然遗产保护局（SNH）与海洋苏格兰科学（MSS）共同实施，于2016年10月4日至6日在洛赫阿什进行的底栖调查，旨在深化对杜伊奇、朗和阿尔什海洋保护区（MPA）内物种及其栖息地分布的认识。调查中，通过在16个站点使用MSS的MRV阿尔巴·纳·马拉船只进行的下拉式视频漂移技术，实现了这一目标。此外，本次调查亦有助于优化邻近部分重叠的特殊保护区域（SAC）的栖息地指令附件1特征的分布监测计划，并对MPA内受保护特征的分布进行了研究。通过对海底视频的分析，利用图像描绘了海底的物理结构及物种群落特性。对航行轨迹及其段落进行了评估，以确定受保护特征、其他重要管理因素（PMFs）的存在，以及具有公认保护重要性的物种和栖息地。
