Video surveys of long spined sea urchin (Centrostephanus rodgersii) barrens habitat, North Bruny Island, 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 North Bruny Island region, and its 3 subsites: Patrick's Bight, Trumpeter Point and Yellow Bluff.

本研究通过拖曳式水下视频系统（towed underwater video system）对岩礁生境（rocky reef habitat）开展调查，以此估算C. rodgersii荒礁的空间分布范围。本次采样作业覆盖塔斯马尼亚东海岸的13个区域，每个区域下设3个子采样点；本数据集仅涵盖北布鲁尼岛区域及其下辖的3个子采样点：帕特里克湾（Patrick's Bight）、号手角（Trumpeter Point）与黄崖（Yellow Bluff）。
