Video surveys of long spined sea urchin (Centrostephanus rodgersii) barrens habitat, Fortescue Bay, eastern Tasmania

The spatial extent of C. rodgersii "barrens" was estimated by surveying rocky reef habitat with a towed underwater video system. Sampling took place at 13 regions along the east coast of Tasmania, each comprising 3 subsites, this dataset refers to the Fortescue Bay region, and its 3 subsites: Lanterns, Munroe Bight and Thumbs.

本研究通过拖曳式水下视频系统（towed underwater video system）对岩礁生境开展调查，以此估算C. rodgersii海胆形成的海胆荒礁的空间分布范围。采样工作在塔斯马尼亚东海岸的13个区域展开，每个区域包含3个次级采样点（subsites）；本数据集特指福蒂斯丘湾（Fortescue Bay）区域及其下辖的3个次级采样点：灯笼礁（Lanterns）、门罗湾（Munroe Bight）与拇指礁（Thumbs）。
