NERP Marine Biodiversity Hub, Theme 1 - Flinders Commonwealth Marine Reserve Pilot Survey- Shelf Baited Underwater Video (BRUV) component

The Flinders CMR survey was a pilot study undertaken in August 2012 as part of the National Marine Biodiversity Hub's National monitoring, evaluation and reporting theme. The aim of this theme is to develop a bluepint for the sustained monitoring of the South-east Commonwealth Marine Reserve Network. The particular aims of the survey were twofold; 1) to contribute to an inventory of demersal and epibenthic conservation values in the reserve and 2) to test methodologies and deployment strategies in order to inform future survey design efforts. Several gear types were deployed; including multibeam sonar, shallow-water (less than 150m) Baited Remote Underwater Video (BRUVs), deep- water BRUVs, towed video and digital stereo stills. This resource contains the shallow-water BRUV footage captured on the FLinders CMR shelf (less than 150 m).Stereo BRUV's were deployed using a probabalistic and spatially-balanced survey design called Generalized Random Tessellation Stratified (GRTS). Habitats were identified in a previous multibeam survey and consisted of 'mixed reef' (containing patchy reef) and sand. Mixed reef habitat was targeted in this survey (9 GRTS mixed reef sites versus 3 sand sites). A total of 60 stereo BRUVs were deployed.Data contained here represents footage collected using these drops and the associated scored data (abundance (MaxN) and lengths).

弗林德斯联邦海洋保护区（Flinders Commonwealth Marine Reserve，简称Flinders CMR）调查是2012年8月开展的试点研究，隶属于国家海洋生物多样性中心（National Marine Biodiversity Hub）的国家监测、评估与报告主题项目。该主题的核心目标是制定东南联邦海洋保护区网络的长期监测蓝图。本次调查的具体目标分为两项：一是为该保护区内的底栖（demersal）与表底栖（epibenthic）保护价值名录补充基础数据；二是测试调查方法与部署策略，为后续的调查设计工作提供科学参考。本次调查共部署了多类采样设备，包括多波束声呐、浅海（水深小于150米）诱饵式远程水下视频系统（Baited Remote Underwater Video，简称BRUVs）、深海BRUVs、拖曳式视频系统以及立体数字静态摄影设备。本数据集收录了弗林德斯联邦海洋保护区陆架区域（水深小于150米）采集的浅海BRUVs影像资料。本次调查采用名为广义随机镶嵌分层抽样（Generalized Random Tessellation Stratified，简称GRTS）的概率化空间平衡调查设计，完成立体BRUVs的部署。此前的多波束调查已完成栖息地分类，涵盖“混合礁”（包含斑块状礁体）与沙质生境两类。本次调查优先针对混合礁生境开展采样，共设置9个GRTS混合礁采样点与3个沙质生境采样点。本次共计部署60套立体BRUVs。本数据集包含上述采样点采集的影像资料，以及配套的评分数据，包括丰度（MaxN，即最大观测个体数）与体长数据。
