Eastern Tasmania Marine Heatwave Atlas

We have used a quantitative definition of marine heatwaves to detect all events which have occurred in 12 regions across the continental shelf off eastern Tasmania over 1993-2015. For each event in each region this atlas includes information on (i) event properties including intensity, duration and depth, (ii) maps of regional ocean circulation and ocean temperature during the event, and (iii) maps of regional atmospheric conditions during the event (air temperature and surface wind). Also provided are summary statistics including the typical conditions which give rise to marine heatwaves in each region and annual time series demonstrating interannual variability and long term trends in marine heatwave properties. Provided is a comprehensive document presenting the atlas and a set of CSV files containing the underlying data.

本研究采用海洋热浪（marine heatwaves）的定量判定标准，对1993年至2015年间塔斯马尼亚东部近海大陆架的12个海域内发生的全部海洋热浪事件完成识别。本图集针对每个海域的每一次海洋热浪事件，提供以下三类信息：(i) 事件属性数据，包括强度、持续时长与发生深度；(ii) 事件发生时段的区域海洋环流与海水温度分布图；(iii) 事件发生时段的区域大气条件分布图（涵盖气温与地表风速）。本数据集同时附带统计汇总资料，涵盖各海域触发海洋热浪的典型环境条件，以及用于展示海洋热浪属性年际变率与长期变化趋势的年度时间序列数据。此外还包含一份完整阐述该图集的技术文档，以及一套存储基础数据的逗号分隔值（CSV）文件。
