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

The data is the percent algal cover 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 and megafaunal invertebrate abundance 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. The originating metadata record http://metadata.imas.utas.edu.au/geonetwork/srv/eng/metadata.show?uuid=75fc95bf-e4b4-4d39-9ac3-0433669648de contains project details, additional contacts and on-line resources.本数据集为通过样带计数法开展水下视觉普查所得到的塔斯马尼亚周边岩礁生境的藻类覆盖百分比数据。该数据集隶属于一套更大的综合调查数据集，该数据集同时针对该区域开展了鱼类与大型无脊椎动物的丰度调查。这套整合后的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：首次普查于1992至1995年间开展，并于2006至2007年在同一调查点位重复进行。 原始元数据记录（链接：http://metadata.imas.utas.edu.au/geonetwork/srv/eng/metadata.show?uuid=75fc95bf-e4b4-4d39-9ac3-0433669648de）包含项目详情、额外联系方式及在线资源。
