BRUVS deployments in Oceanic Shoals Commonwealth Marine Reserve (Timor Sea), Western Australia (NERP)

Stereo-Baited Remote Underwater Video Stations (BRUVS) were deployed and retrieved in targeted shallow seabed environments within the proposed Oceanic Shoals Commonwealth Marine Reserve (CMR) in the Timor Sea. The survey concentrated on shelf habitats (< 200m) of the western part of the Oceanic Shoals CMR and included potential biodiversity hotspots such as pinnacles, banks and shoals. In total, 56 stereo-BRUVS were deployed between 31 and 77 metres for one hour according to a regular random sampling design, with minimum spacing of 400 m to ensure independence among samples. This yielded 56 hours of video footage which was subsequently analysed and all species and their relative abundances recorded.
The Marine Biodiversity Survey of the proposed Oceanic Shoals Commonwealth Marine Reserve (CMR) in the Timor Sea was a research collaboration between the Australian Institute of Marine Science (AIMS), Geoscience Australia (GA), University of Western Australia (UWA) and the Museum & Art Gallery of the Northern Territory (MGNT). The survey was undertaken between 12 September and 6 October 2012 on the AIMS Research Vessel, RV Solander, and formed part of the National Environmental Research Program (NERP) Marine Biodiversity Hub Theme 4: Regional Biodiversity Discovery to Support Marine Bioregional Plans.

本研究在帝汶海拟议的大洋浅滩联邦海洋保护区（Commonwealth Marine Reserve, CMR）内的目标浅海海底环境中，布设并回收了立体诱饵式远程水下视频站（Baited Remote Underwater Video Stations, BRUVS）。本次调查聚焦于大洋浅滩CMR西部的陆架生境（水深<200米），涵盖尖峰礁、沙洲群等潜在生物多样性热点区域。研究采用常规随机抽样设计，共布设56台立体BRUVS，布设水深介于31至77米，单次布设观测时长为1小时，采样点最小间距设置为400米以保障样本独立性。本次调查累计获取56小时的视频素材，后续对该素材开展分析，记录了所有观测物种及其相对丰度。本次针对帝汶海拟议大洋浅滩联邦海洋保护区的海洋生物多样性调查，由澳大利亚海洋科学研究所（Australian Institute of Marine Science, AIMS）、澳大利亚地球科学局（Geoscience Australia, GA）、西澳大利亚大学（University of Western Australia, UWA）以及北领地博物馆与美术馆（Museum & Art Gallery of the Northern Territory, MGNT）联合开展。调查于2012年9月12日至10月6日期间，依托澳大利亚海洋科学研究所“索兰德号”（RV Solander）研究船实施，为国家环境研究计划（National Environmental Research Program, NERP）海洋生物多样性枢纽主题4——“支撑海洋生物区域规划的区域生物多样性发现”的组成部分。
