This record provides an overview of the NESP Marine and Coastal Hub bridging study - "Aerial survey of the Southern Right Whale ‘western’ sub-population off southern 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 have been conducted across the southern Australian coast from Perth, WA to Ceduna, SA since 1993, as part of a long-term program to monitor their recovery. The surveys data provide a long-term population trend for this ‘western’ population, and provide an understanding of connectivity with the ‘eastern’ population as part of a national population assessment. The NESP Marine Biodiversity Hub funded the aerial surveys in 2015–2020 and the Marine and Coastal Hub funded the survey in 2021. (See Project 1.26: https://catalogue.aodn.org.au/geonetwork/srv/eng/catalog.search#/metadata/b85b2c7d-4631-477a-9217-2cae65f9cf0a)<br /> <br /> The 2022 survey ensures an uninterrupted time series in the long-term population trend data for this Endangered species. This is particularly important given the non-annual breeding cycle (typically every three years), such that annual surveys are essential to maintain an acceptable level of precision in estimating population trends and key life history parameters (calving intervals) to track the recovery of the species. Continued monitoring of the population is needed to evaluate whether there is a longer term and continuous change (in population size and calving intervals) in the population as indicated by recent sightings and population trend data.<br /> <br /> Outputs<br /> • Estimate of relative abundance and population trend compared to long-term aerial survey sightings [dataset]<br /> • Individual whale photo-identification data - 2021-22 season [imagery - published to ARWPIC]<br /> • Final technical report detailing overall numbers of southern right whales observed within the survey region, their gender (and life stage where possible) and spatial distribution of individuals [written]

该记录概述了 NESP 海洋和沿海枢纽桥接研究 - “对澳大利亚南部附近的南露脊鲸‘西部’亚群进行空中调查”。有关该项目的具体数据输出，请参阅与此元数据相关的子记录。 .<br /> --------------------<br /> <br/> 自 1993 年以来，作为监测南露脊鲸恢复情况长期计划的一部分，对澳大利亚南部海岸从华盛顿州珀斯到南澳州塞杜纳的南露脊鲸进行了空中调查。调查数据提供了南露脊鲸的长期种群趋势。作为国家人口评估的一部分，NESP 海洋生物多样性中心资助了 2015 年至 2020 年的航空调查以及海洋和沿海调查。 Hub 于 2021 年资助了这项调查。（参见项目 1.26：https://catalogue.aodn.org.au/geonetwork/srv/eng/catalog.search#/metadata/b85b2c7d-4631-477a-9217-2cae65f9cf0a）<br / > <br/> 2022 年的调查确保了该濒危物种的长期种群趋势数据的不间断时间序列，鉴于非年度繁殖周期（通常每三年），这一点尤为重要，因此年度调查对于维持可接受的水平至关重要。准确估计种群趋势和关键生活史参数（产犊间隔）以跟踪物种的恢复需要持续监测种群，以评估是否存在长期和持续的变化（种群规模和产犊间隔）。这最近的目击事件和人口趋势数据表明的人口。<br /> <br/> 输出<br /> • 与长期航空观测目击数据相比相对丰度和种群趋势的估计[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，详细说明调查区域内观察到的南露脊鲸总数、性别（以及可能的生命阶段）和个体的空间分布[书面]
