2017 Scottish Natural Heritage (SNH) Wester Ross benthic camera survey

The primary aim of this benthic survey in Wester Ross, run by SNH and Marine Scotland Science (MSS) for SNH on the 14th - 15th May 2017 using MSS vessel MRV Alba na Mara (cruise 0717A), was to refine knowledge of MPA protected feature distribution using quantitative drop-down camera. Dropdown video drifts were undertaken at 35 stations. 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; in particular maerl bed and flameshell bed. Runs traversing a sequence of habitats were split into corresponding segments. Species present were, as far as possible, identified and quantified using the semi-quantitative MNCR SACFOR scale and biotopes were allocated based on the physical and biological attributes.

本次由苏格兰自然遗产局（SNH）与海洋苏格兰科学（MSS）联合执行的西罗斯地区底栖调查，旨在2017年5月14日至15日通过MSS的MRV Alba na Mara（巡航编号0717A）船只进行，主要目标系通过定量式水下摄像机对保护区域（MPA）内特征分布的精细掌握。在35个站点进行了水下摄像机拖曳拍摄。通过对海底视频的分析，利用图像描述海底的物理结构及生物群落组成。对航行路径及其段落进行了评估，以确定保护特征及其他重要海洋生物特征的存在，以及对具有认可保护价值的物种和栖息地的存在性评估，尤其是对牡蛎床和扇贝床的评估；穿越一系列栖息地的航行路径被分割为相应的段落。尽可能地对现有物种进行识别和量化，采用半定量式的MNCR SACFOR标度，并根据物理和生物属性分配生物群落。
