2001 Scottish Natural Heritage (SNH) Sound of Barra sublittoral habitats joint broad-scale mapping survey

A comprehensive biotope mapping survey of the sublittoral habitats was undertaken in August 2001, by a collaborative research group comprising staff from the University of St Andrews, Heriot-Watt University and SNH. Rapid broadscale remote acoustic mapping techniques were utilised and 'groundtruth' data were collected to enable the interpretation of of acoustically classed seafloor maps. Groundtruthing data were collected in the field using a range of sampling techniques including snorkel diver-based observations with video, observations through a glass bottomed bucket, cores, video imagery collected by remotely operated vehicle (ROV) or drop-down video and grab sampling of sedimentary habitats for infaunal and sediment analyses. It is the MNCR diver data (20 stations) that is currently present in this Marine Recorder Survey.

2001年8月，由圣安德鲁斯大学、赫瑞瓦特大学及苏格兰自然遗产局（SNH）工作人员组成的联合研究团队，对次海底生境进行了全面的地带图测绘调查。在此过程中，采用了快速大范围的远程声学测绘技术，并收集了‘实地验证’数据，以便对声学分类的海底地图进行解读。实地验证数据通过多种采样技术收集于现场，包括潜水员在水面上进行的带视频观察、通过玻璃底桶进行的观察、钻孔采样、由遥控潜水器（ROV）或投下视频和抓取沉积生境样本，以进行底栖动物和沉积物分析。目前，该海洋记录调查中包含的是MNCR潜水员数据（20个站点）。
