EcoRRAP Coral Demographic Data

This dataset provides information on coral survival and growth for eleven taxa at EcoRRAP sites across the Great Barrier Reef and Torres Strait (see SOP #14: Reef monitoring sampling methods | AIMS).This dataset was generated through the segmentation of coral colonies on EcoRRAP orthomosaics (EcoRRAP Benthic Orthomosaics - AIMS) using the software TagLab. Colonies of specific taxa were identified and digitised on orthomosaics generated from the first year of monitoring. Digitisation was either conducted manually or through the use of an AI classifier followed by manual review and verification. Colony segments were then transferred to the corresponding orthomosaic for the next time point and segments were refined to align with coral colony edges. Growth is recorded here as change in planar area of a colony between time points. This dataset also contains colonies whose species identification has been verified in the field by a coral taxonomist as well as colonies that have been sampled for genetic purposes.A subset of taxa have been uniformly digitised across all EcoRRAP sites, including: table Acropora (where possible, A. hyacinthus and A. cytherea were identified to species level), corymbose Acropora (where possible, A. millepora and A. tenuis were identified to species level), digitiate Acropora (where possible, A. humilis and A. gemmifera were identified to species level), Pocillopora verrucosa, Pocillopora damicornis, Stylophora pistillata, massive Porites (species complex of 7 Porites species), Goniastrea (where possible, G. edwardsi and G. retiformis were identified to species level), and Platygyra. Five additional taxa have been unformly digitised in the Central EcoRRAP cluster to investigate the 2022 bleaching event, however, these taxa have not been consistently digitised in other EcoRRAP sites. These additional taxa include staghorn Acropora, Seriatopora hystrix, Lobophyllia sp., encrusting Montipora, and Isopora sp. Data is currently available for three time points (two transitions) from 2021-2023. Data is available for each year of monitoring in the form of .csv and .shp files as well as in a joined form that links individual coral colonies across all time points.

本数据集涵盖大堡礁与托雷斯海峡EcoRRAP监测点内11个珊瑚类群的存活与生长相关信息（详见SOP #14：珊瑚礁监测采样方法 | 澳大利亚海洋科学研究所（Australian Institute of Marine Science, AIMS））。
本数据集通过使用TagLab软件对EcoRRAP正射影像（EcoRRAP Benthic Orthomosaics - AIMS）中的珊瑚群体进行分割而生成。在监测首年生成的正射影像上，科研人员已完成特定类群珊瑚群体的识别与数字化工作。数字化流程分为两类：一是纯人工手动操作；二是先通过AI分类器完成初步识别，再经人工复核与验证。
随后，分割得到的珊瑚群体影像区块会被匹配至对应时间点的后续正射影像中，并对区块边界进行微调，以贴合珊瑚群体的实际轮廓。本数据集以平面投影面积变化作为珊瑚群体的生长量统计指标。
本数据集既包含经珊瑚分类学家野外实地验证物种鉴定结果的珊瑚群体，也包含已开展遗传学采样的珊瑚群体。
其中，部分类群已在所有EcoRRAP监测点完成标准化数字化，包括：桌形轴孔珊瑚（尽可能鉴定至物种水平，如紫杯轴孔珊瑚(A. hyacinthus)和阔结轴孔珊瑚(A. cytherea)）、伞房状轴孔珊瑚（尽可能鉴定至物种水平，如多孔轴孔珊瑚(A. millepora)和细枝轴孔珊瑚(A. tenuis)）、指状轴孔珊瑚（尽可能鉴定至物种水平，如矮小轴孔珊瑚(A. humilis)和宝石轴孔珊瑚(A. gemmifera)）、疣状杯形珊瑚(Pocillopora verrucosa)、鹿角杯形珊瑚(Pocillopora damicornis)、拟鹿角珊瑚(Stylophora pistillata)、块状多孔珊瑚（包含7个物种的多孔珊瑚复合类群）、蜂巢珊瑚属(Goniastrea，尽可能鉴定至物种水平，如爱德华蜂巢珊瑚(G. edwardsi)和网状蜂巢珊瑚(G. retiformis)）以及扁脑珊瑚属(Platygyra)。
另有5个类群仅在中部EcoRRAP集群监测点完成标准化数字化，用于研究2022年珊瑚白化事件，但未在其他EcoRRAP监测点实现统一数字化。这些额外类群包括：鹿角状轴孔珊瑚、尖枝列孔珊瑚(Seriatopora hystrix)、叶状珊瑚属(Lobophyllia sp.)、壳状微孔珊瑚(encrusting Montipora)以及等轴珊瑚属(Isopora sp.)。
目前本数据集包含2021-2023年共3个时间点（2个时间间隔）的观测数据。各年度监测数据以.csv和.shp格式文件提供，同时也提供了可关联不同时间点单个珊瑚群体的整合格式数据。
