Temperate Australian quantitative spatial and temporal abundance data for rocky reef biota (biodiversity): new Tasmanian MPAs - Kent Group

The data is quantitative abundance of fish and megafaunal invertebrates and algal % cover derived from transect based counts at a wide range of locations across Temperate Australia. The methods are described in detail in Edgar and Barrett (1997). Primarily the data are derived from transects at 5 m depth and/or 10 m depth at each site surveyed. Methods were initially developed for research on temporal changes following protection in Tasmanian MPAs (Maria Is, Tinderbox, Ninepin Point, Governor Island). Further research has collected data in Tasmania, in MPA planning surveys (e.g. St Helens, Waterhouse Region, Low Head, Lillico Beach, Rocky Cape), an oil spill assessment (Low Head), and in studies and surveys in new Tasmania MPAs (Port Davey and the Kent Group). The data represented by this record was collected in the Kent Group. In many cases the dataset involved temporal replication (year scale).

本数据集包含澳大利亚温带区域多采样站点基于样带计数得到的鱼类、大型无脊椎动物定量丰度数据，以及藻类盖度百分比数据。相关方法细节详见Edgar与Barrett（1997）的研究成果。本次调查各站点的采样样带主要设置于5米或10米水深位置。该方法最初为探究塔斯马尼亚海洋保护区（Marine Protected Area, MPA）实施保护后的群落时间动态而开发，首批调查区域包括玛丽亚岛（Maria Is）、廷德博克斯、九针角以及总督岛。后续研究进一步在塔斯马尼亚地区采集了相关数据，涵盖海洋保护区规划调查（如圣海伦斯、沃特斯豪斯区域、洛海德、利利科海滩、洛基角）、油污泄漏评估（洛海德），以及塔斯马尼亚新建海洋保护区（波特戴维与肯特群岛）的相关研究与调查工作。本记录对应的数据集采集自肯特群岛海域。该数据集在多数情况下包含年度尺度的时间重复采样数据。
