The Australian Phytoplankton Database (1844 - ongoing) - abundance and biovolume

There have been many individual phytoplankton datasets collected across Australia since the mid 1900s, but most are unavailable to the research community. We have searched archives, contacted researchers, and scanned the primary and grey literature to collate over 3,600,000 records of marine phytoplankton species from Australian waters from 1844 to the present. Many of these are small datasets collected for local questions, but combined they provide over 170 years of data on phytoplankton communities in Australian waters. Units and taxonomy have been standardised, obviously erroneous data removed, and all metadata included. We have lodged this dataset with the Australian Ocean Data Network (http://imos.aodn.org.au/), allowing public access. The Australian Phytoplankton Database will be invaluable for global change studies, as it allows analysis of ecological indicators of climate change and eutrophication (e.g., changes in distribution; diatom:dinoflagellate ratios). In addition, the standardised conversion of abundance records to biomass provides modellers with quantifiable data to initialise and validate ecosystem models of lower marine trophic levels. There is a static snapshot of the database as at March 2016 (http://dx.doi.org/10.4225/69/56454b2ba2f79), and this has been documented in a Scientific Data Publication. This metadata record provides access to the dynamic (most recent) version of the database and was based on the following CSIRO metadata record: https://marlin.csiro.au/geonetwork/srv/eng/search?uuid=1836cea6-317d-1608-e053-08114f8c81ba.

自20世纪中期以来，澳大利亚各地已收集了多份独立的浮游植物（phytoplankton）数据集，但其中多数未对科研界开放。我们通过检索档案库、联系相关研究者、扫描原始文献与灰色文献（grey literature），整合得到了1844年至今澳大利亚海域内超过360万条海洋浮游植物物种记录。其中多数是为解决本地特定研究问题而采集的小型数据集，但将其整合后，便可提供170余年来澳大利亚海域浮游植物群落的长期观测数据。我们已统一了数据单位与分类体系，剔除了明显有误的记录，并补充了全部元数据（metadata）。本数据集已提交至澳大利亚海洋数据网络（Australian Ocean Data Network，http://imos.aodn.org.au/），实现了公众可访问。澳大利亚浮游植物数据库将对全球变化研究具有重要价值，因其可用于分析气候变化与富营养化的生态指示因子（例如物种分布变化、硅藻（diatom）-甲藻（dinoflagellate）比值）。此外，将丰度记录标准化转换为生物量数据，可为建模人员提供可量化的数据集，用于初始化并验证海洋低营养级生态系统模型。该数据库存在2016年3月的静态快照版本（http://dx.doi.org/10.4225/69/56454b2ba2f79），相关内容已在《科学数据》（Scientific Data）期刊的研究论文中进行了记载。本元数据记录提供了该数据库的动态（最新）版本，其基于以下澳大利亚联邦科学与工业研究组织（CSIRO）元数据记录：https://marlin.csiro.au/geonetwork/srv/eng/search?uuid=1836cea6-317d-1608-e053-08114f8c81ba。
