In this study we examined cyanobacterial mat distribution during a severe coral bleaching event at Lizard Island (Great Barrier Reef, Australia). This study was based on the cover of cyanobacterial mats, and other benthic components, from inside 1 m2 photoquadrats (n = 349). The photoquadrats were spread across 19 transects around Lizard Island and photoqaudrats were fixed (i.e. the same areas were repeatedly sampled/photographed). Photoquadrats were repeatedly sampled at six points in time between February 2016 and January 2021, with particularly focused sampling (three times in 2016) around the severe coral bleaching event that affected Lizard Island in 2016. Photoquadrats were analysed to determine benthic cover of major benthic components, under 40 randomly stratified points in each photoquadrat, using the software photoquad V_1_4. The CSV file in this dataset contains the raw benthic cover data analysed in this paper. The numbers under each benthic component in the dataset relate to the number of points that fell on that component in each quadrat.

本研究针对澳大利亚大堡礁蜥蜴岛发生的严重珊瑚白化事件期间的底栖蓝藻垫分布情况展开调查。本研究基于349个1平方米照片样方（photoquadrat）内的蓝藻垫及其他底栖生物组分的盖度数据开展分析。

这些照片样方分布于蜥蜴岛周边的19条样带之上，且均为固定样方（即对同一区域进行重复采样与拍摄）。

研究于2016年2月至2021年1月间分6个时间节点对照片样方进行重复采样；其中针对2016年影响蜥蜴岛的严重珊瑚白化事件，于当年开展了3次重点采样。

本研究使用photoquad V_1_4软件，对每个照片样方内的40个随机分层采样点进行分析，以确定主要底栖生物组分的盖度。

本数据集内的CSV文件包含本文所分析的原始底栖盖度数据。数据集内各底栖生物组分下的数值，代表对应样方中落点于该组分的采样点数量。
