IMOS - National Reef Monitoring Network Sub-Facility - Global reef fish abundance and biomass

The National Reef Monitoring Network brings together shallow reef surveys conducted around Australia into a centralised database. The IMOS National Reef Monitoring Network sub-Facility collates, cleans, stores and makes this data rapidly available from contributors including: Reef Life Survey, Parks Australia, Department of Biodiversity, Conservation and Attractions (Western Australia), Department of Environment, Water and Natural Resources (South Australia), Department of Primary Industries (New South Wales), Tasmanian Parks and Wildlife Service and Parks Victoria.The data provided by the National Reef Monitoring Network contributes to establishing and supporting national marine baselines, and assisting with the management of Commonwealth and State marine reserves. Reef Life Survey (RLS) and the Australian Temperate Reef Network (ATRC) aims to improve biodiversity conservation and the sustainable management of marine resources by coordinating surveys of rocky and coral reefs using scientific methods, with the ultimate goal to improve coastal stewardship. Our activities depend on the skills of marine scientists, experienced and motivated recreational SCUBA divers, partnerships with management agencies and university researchers, and active input from the ATRC partners and RLS Advisory Committee.RLS and ATRC data are freely available to the public for non-profit purposes, so not only managers, but also groups such as local dive clubs or schools may use these data to look at changes over time in their own local reefs. By making data freely available and through public outputs, RLS and ATRC aims to raise broader community awareness of the status of Australia's marine biodiversity and associated conservation issues.This dataset contains records of bony fishes and elasmobranchs collected by Reef Life Survey (RLS) and Australian Temperate Reef Collaboration (ATRC) divers and partners along 50m transects on shallow rocky and coral reefs using standard methods. Abundance information is available for all species recorded within quantitative survey limits (50 x 5 m swathes either side of the transect line, each distinguished as a 'Block'), with size and biomass data also included when available. These observations form the Method 1 component of the surveys.This dataset supersedes the RLS specific "Reef Life Survey (RLS): Global reef fish dataset" collection that was available at https://catalogue-rls.imas.utas.edu.au/geonetwork/srv/en/metadata.show?uuid=9c766140-9e72-4bfb-8f04-d51038355c59 (provision of data was stopped in June 2021).

国家珊瑚礁监测网络（National Reef Monitoring Network）将澳大利亚各地开展的浅海礁调查整合至一个集中式数据库中。IMOS国家珊瑚礁监测网络子设施（IMOS National Reef Monitoring Network sub-Facility）负责对来自以下贡献方的数据进行整理、清洗、存储并快速开放：珊瑚礁生活调查（Reef Life Survey, RLS）、澳大利亚公园管理局（Parks Australia）、西澳大利亚州生物多样性、保护与旅游部（Department of Biodiversity, Conservation and Attractions）、南澳大利亚州环境、水与自然资源部（Department of Environment, Water and Natural Resources）、新南威尔士州初级产业部（Department of Primary Industries）、塔斯马尼亚公园与野生动物服务局（Tasmanian Parks and Wildlife Service）以及维多利亚州公园管理局（Parks Victoria）。
国家珊瑚礁监测网络提供的数据，有助于建立并支撑国家海洋基准线，同时助力联邦与州级海洋保护区的管理工作。
珊瑚礁生活调查（RLS）与澳大利亚温带珊瑚礁协作组（Australian Temperate Reef Collaboration, ATRC）旨在通过科学方法协调岩礁与珊瑚礁调查，以此推动生物多样性保护与海洋资源的可持续管理，最终目标是提升海岸治理水平。
本项目的开展依托海洋科学家、经验丰富且积极性高涨的休闲水肺潜水员的专业能力，同时依赖与管理机构、高校研究者的合作，以及ATRC合作伙伴与RLS咨询委员会的积极建言。
RLS与ATRC的数据面向公众免费开放，仅供非营利性使用，因此不仅管理人员，当地潜水俱乐部、学校等团体也可利用这些数据研究本地珊瑚礁随时间发生的变化。
通过免费开放数据并开展公开成果输出，RLS与ATRC旨在提升公众对澳大利亚海洋生物多样性现状及相关保护议题的认知广度。
本数据集收录了由RLS与ATRC潜水员及合作伙伴，通过标准方法在浅海岩礁与珊瑚礁的50米样线上采集得到的硬骨鱼类与软骨鱼类（elasmobranchs）记录。
在定量调查范围内（样线两侧各50米×5米的区域，每个区域被标记为一个"区块"）记录的所有物种均有丰度信息，若有可用数据则同时包含体长与生物量信息。
此类观测构成了本次调查的方法1组分。
本数据集替代了此前可通过https://catalogue-rls.imas.utas.edu.au/geonetwork/srv/en/metadata.show?uuid=9c766140-9e72-4bfb-8f04-d51038355c59获取的专属RLS数据集"Reef Life Survey (RLS): Global reef fish dataset"，该数据集的数据提供服务已于2021年6月终止。
