Temperate Australian quantitative spatial and temporal abundance data for rocky reef biota (biodiversity): long-term Tasmanian MPAs - Maria Island

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 long-term MPAs (Maria Is, Tinderbox, Ninepin Point, Governor Island), and the data represented by this record has been collected at Maria Island. In many cases the dataset involves temporal replication (year scale), particularly for the core Tasmanian MPAs represented by this record.

本数据集包含澳大利亚温带区域多个采样点基于样带（transect）计数法得到的鱼类、大型无脊椎动物定量丰度，以及藻类盖度百分比数据。该数据集的采样方法细节详见Edgar与Barrett（1997）的研究成果。本次采集的数据主要来自各调查站点5米水深及/或10米水深的样带采样。本采样方法最初为研究塔斯马尼亚长期海洋保护区（Marine Protected Areas，MPAs，涵盖Maria岛、Tinderbox、Ninepin Point、Governor Island）实施保护后的时间序列变化而开发，且本记录所涵盖的数据均采集自Maria岛。多数情况下，本数据集包含年际尺度的重复采样数据，尤其针对本记录所代表的塔斯马尼亚核心海洋保护区站点。
