The Australian Phytoplankton Database (1844 - 2016) - abundance and biovolume (SUPERSEDED BY ONGOING COLLECTION)

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 3,665,221 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. This is a static snapshot of the database as at March 2016.

自20世纪中期以来，澳大利亚各地已收集了大量独立的浮游植物（phytoplankton）数据集，但其中大多数尚未向研究界开放。我们通过检索档案、联系研究人员以及查阅原始文献与灰色文献，整理出1844年至今澳大利亚海域海洋浮游植物物种的3,665,221条记录。这些数据集中的多数为针对局部问题收集的小型数据集，但整合后可提供澳大利亚海域浮游植物群落超过170年的连续数据。我们已对数据单位与分类学（taxonomy）信息进行标准化处理，剔除明显错误数据，并完整保留所有元数据。该数据集已提交至澳大利亚海洋数据网络（Australian Ocean Data Network，网址：http://imos.aodn.org.au/），可供公众访问。澳大利亚浮游植物数据库（Australian Phytoplankton Database）对全球变化研究具有不可估量的价值，因其可用于分析气候变化与富营养化（eutrophication）的生态指标（如分布变化、硅藻与甲藻比例等）。此外，将丰度记录标准化转换为生物量，可为建模人员提供量化数据，用于初始化与验证海洋低营养级生态系统模型。本数据集为该数据库截至2016年3月的静态快照版本。如需获取动态数据库中的后续新增数据，请查阅以下元数据记录：https://catalogue-imos.aodn.org.au:443/geonetwork/srv/api/records/75f4f1fc-bee3-4498-ab71-aa1ab29ab2c0
