Temperate Australian quantitative spatial and temporal abundance data for rocky reef biota (biodiversity): Tasmanian MPA planning surveys and opportunistic surveys

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 MPA planning surveys and for opportunistic surveys such as the Low Head oil spill assessment. In many cases the dataset involved temporal replication (year scale).

本数据集涵盖澳大利亚温带海域多站点基于样带计数法获取的鱼类、大型无脊椎动物定量丰度数据，以及藻类盖度数据。相关方法细节详见Edgar与Barrett（1997）的研究成果。本次调查的各站点采样样带主要设置于5米和/或10米水深区域。

该方法最初为研究塔斯马尼亚海洋保护区（Marine Protected Area, MPA）实施保护后的时间序列变化而开发，应用站点包括玛丽亚岛（Maria Is）、廷德博克斯（Tinderbox）、九针角（Ninepin Point）以及总督岛（Governor Island）。后续研究在塔斯马尼亚开展了多类数据采集工作，涵盖海洋保护区规划调查（例如圣海伦斯[St Helens]、沃特斯豪斯地区[Waterhouse Region]、洛黑德[Low Head]、利利科海滩[Lillico Beach]、罗基岬[Rocky Cape]）、石油泄漏评估（洛黑德），以及针对塔斯马尼亚新建海洋保护区的研究与调查（波特戴维[Port Davey]与肯特群岛[Kent Group]）。

本记录所代表的数据集采集自海洋保护区规划调查，以及诸如洛黑德石油泄漏评估这类应急调查。多数情况下，该数据集包含时间尺度为年度的重复采样数据。
