Loch Roag, Lewis: lifeforms map area 4

This evaluation of the RoxAnn system as a tool for mapping the distribution of kelp biotopes has been undertaken as part of the BioMar Project which is funded by the European Community through the LIFE Programme. The central aim of the present project was to evaluate of the RoxAnn system as a tool for mapping the distribution of kelp on the north west coast of the Isle of Lewis. If the RoxAnn system could map the distribution of kelp biotopes, it could prove to be a valuable tool for gathering resource data to assist management decisions - for instance assessing kelp harvesting proposals. The BioMar team carried out the field work for this study from August 27 to September 2, 1994. Five areas were studied on the NW coast of Lewis, Western Isles: four areas within East Loch Roag and the open coast from East Loch Roag to Bragar. Biological data were collected for 59 remote video samples, and the change in kelp density with depth measured at ten sites using SCUBA diving.

本次对 RoxAnn 系统作为海藻生物群落分布映射工具的评估，是 BioMar 项目的一部分，该项目由欧洲共同体通过 LIFE 计划资助。本项目的主要目标是评估 RoxAnn 系统在绘制莱斯特岛西北海岸海藻分布方面的应用价值。若 RoxAnn 系统能够绘制出海藻生物群落的分布图，则有望成为收集资源数据以辅助管理决策的宝贵工具——例如，评估海藻收割提议。BioMar 团队在 1994 年 8 月 27 日至 9 月 2 日期间进行了实地考察。研究覆盖了莱斯特岛西北海岸五个区域：罗格东湾内的四个区域以及从罗格东湾至布拉格的开放海岸。收集了 59 个远程视频样本的生物数据，并在十个地点使用潜水设备测量了水深与海藻密度之间的关系。
