Condition of rocky reef communities around Tasmania: invertebrate surveys, Australia (1992-1995 and 2006-2007)

The data is the quantitative abundance of megafaunal invertebrates derived from underwater visual census methods involving transect counts at rocky reef sites around Tasmania. This data forms part of a larger dataset that also surveyed fish abundance and algal cover for the area. The aggregated dataset allows examination of changes in Tasmanian shallow reef floral and faunal communities over a decadal scale - initial surveys were conducted in 1992-1995, and again at the same sites in 2006-2007.

本数据集包含通过水下视觉普查方法获取的塔斯马尼亚周边岩礁生境大型无脊椎动物（megafaunal invertebrates）定量丰度数据，该普查采用样带计数法开展。该数据集隶属于一套更大的综合数据集，后者同时针对该区域开展了鱼类丰度与藻类覆盖度调查。这套整合数据集可用于分析塔斯马尼亚浅海岩礁动植物群落的十年尺度变化——首次调查于1992年至1995年间开展，后续于2006年至2007年在同一采样点完成复访。原始元数据记录（http://metadata.imas.utas.edu.au/geonetwork/srv/eng/metadata.show?uuid=9aee213b-ab23-4321-9994-f7db2f6b2e78）包含项目详情、额外联系方式及在线资源。
