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

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 Port Davey. In many cases the dataset involved temporal replication (year scale).

本数据集涵盖澳大利亚温带区域多采样点基于样带（transect）计数所得的鱼类、大型无脊椎动物定量丰度数据，以及藻类盖度百分比数据。相关方法细节已在Edgar与Barrett（1997）的研究中详细阐述。数据主要来源于各调查站点5米水深和/或10米水深布设的样带。该方法最初用于塔斯马尼亚海洋保护区（Marine Protected Areas, MPAs）内受保护区域的时间变化研究，涉及站点包括玛丽亚岛（Maria Is）、廷德博克（Tinderbox）、九针角（Ninepin Point）及总督岛（Governor Island）。后续研究在塔斯马尼亚多地进一步采集了数据，涵盖海洋保护区规划调查（如圣海伦斯[St Helens]、沃特斯豪斯区域[Waterhouse Region]、洛海德[Low Head]、利利科海滩[Lillico Beach]、洛基角[Rocky Cape]）、漏油事故生态评估（洛海德），以及塔斯马尼亚新建的两处海洋保护区——戴维港（Port Davey）与肯特群岛（Kent Group）——的相关研究与调查。本数据集记录对应的数据采集自戴维港（Port Davey）。本数据集多数情况下包含年际尺度的重复采样。
