This record provides an overview of the NESP Marine and Coastal Hub bridging study - "A photo-identification study of southern right whales to update aggregation area classification in the southwest of Australia". For specific data outputs from this project, please see child records associated with this metadata.<br /> --------------------<br /> <br /> Aerial surveys of southern right whales (Eubalaena australis) have been conducted across the southern Australian coast from Perth (W.A.) to Ceduna (S.A.) since 1993, as part of a long-term program to monitor the recovery, and inform the Conservation Management Plan (2011-2021), for this Endangered species (under the EPBC Act). The 2020 aerial survey recorded substantially lower numbers of whales than in the previous 13 years, and the lowest number of non-calving whales since the program started. An aerial survey conducted by this project in August 2021 will provide a relative estimate of annual population size for determining longer term population trends and contribute to determining if 2020 was an anomalous year or an indicator of some longer-term change to recent recovery rates and the female breeding cycle.<br /> <br /> Outputs<br /> • Aerial whale survey data (counts by size class, number, and location) - 2021-22 season [dataset]<br /> • Individual whale photo-identification data - 2021-22 season [imagery - published to ARWPIC]<br /> • Final technical report with analysed data, including a short summary of recommendations for policy makers of key findings [written]

该记录概述了 NESP 海洋和沿海中心桥接研究 - “对南露脊鲸进行照片识别研究，以更新澳大利亚西南部的聚集区域分类”。有关该项目的具体数据输出，请参阅相关子记录。有了这个元数据。<br /> --------------------<br /> <br/> 自 1993 年以来，我们一直在从珀斯（西澳州）到塞杜纳（南澳州）的澳大利亚南部海岸对南露脊鲸（Eubalaena australis）进行空中调查，作为监测恢复情况并为保护管理计划提供信息的长期计划的一部分(2011-2021)，对于这种濒临灭绝的物种（根据 EPBC 法案），2020 年航空调查记录的鲸鱼数量大大低于以前的数量。该项目于 2021 年 8 月进行的空中调查将提供年度种群规模的相对估计，以确定长期种群趋势，并有助于确定 2020 年是否是 2020 年。异常年份或近期恢复率和雌性繁殖周期发生一些长期变化的指标。<br /> <br/> 输出<br /> • 鲸鱼空中调查数据（按大小类别、数量和位置进行计数）- 2021-22 季节[数据集]<br /> • 鲸鱼个体照片识别数据 - 2021-22 季节 [图像 - 发布到 ARWPIC]<br /> • 最终技术报告，包含分析数据，包括针对主要发现的政策制定者的建议的简短摘要[书面]
