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，以此估算罗氏长棘海胆（C. rodgersii）形成的"海胆荒漠（barrens）"的空间分布范围。采样工作在塔斯马尼亚（Tasmania）东海岸的13个区域内实施，每个区域包含3个子样点。本数据集仅对应富特斯科湾（Fortescue Bay）区域及其下辖的3个子样点：兰滕斯（Lanterns）、门罗湾（Munroe Bight）与桑布斯（Thumbs）。
