IMOS National Reference Station (NRS) - Phytoplankton Abundance and Biovolume

This dataset comprises the phytoplankton abundance and biovolume estimates of a broader sampling program carried out by the Plankton National Reference Station within the Integrated Marine Observing system. Regular monthly phytoplankton samples are undertaken at the stations as part of a larger water sampling program by the Australian National Reference Stations. In total nine stations are sampled regularly around the Australian coastline. Sampling is conducted monthly (Esperance and Ningaloo 3 monthly) off small vessels at each of the nine reference stations. The sampling is an integrated water sample collected with niskin bottles at 10m depth intervals and preserved in lugols solution. The depth of the sample varies at each station. The plankton ecology lab (based in Queensland) will analyse the samples collected for: 1. Community composition / abundance (cells/l) 2. Biovolume (um3/L). Data storage and access is planned to be interoperable with other national and international programs through the IMOS Infrastructure. Station metadata can be found through this resource. Data is available freely via the AODN portal: https://portal.aodn.org.au. As the taxonomic resolution of the data has changed over time, due to continual training, it is important that users refer to the change log tables included in your data download. These will provide information on the validity of the taxa, from what date we have been identifying certain taxa etc. Classification fields may be blank depending on the level to which that taxa has been identified, i.e. if only identified to family, genus and species will be blank .

These data are from the National Mooring Network, part of the Integrated Marine Observing System (IMOS) - IMOS is a national collaborative research infrastructure, supported by the Australian Government.

Each NRS collects its own zooplankton samples and sends them to the Hobart CSIRO O&A laboratories for analysis.

Resource lineage

Statement: Data sampling is being conducted as part of a larger IMOS monitoring program. The zooplankton samples are analysed at the Plankton Ecology Lab at CSIRO O&A, Hobart. The samples are settled in a 1000 ml measuring cylinder for 24 hours. The top 900ml is siphoned off once settled and the remainder is transferred into a 100ml measuring cylinder and left to settle for 24 hours. Once settled the top 90 ml is siphoned off from these samples and the remainder is transferred into a sample jar. This is gently agitated and a 1ml sample is taken and transferred into a Segdwick rafter. The whole sample is scanned at 100x magnification to count large cells. The sample is then counted at 200x magnification to count up to 200 cells of one taxa or up to 400 squares of the Sedgwick rafter. Finally, the sample is counted at 640x magnification for small flagellates, up to 200 cells of one taxa or 20 squares on the Sedgwick rafter. These counts are then converted to cells / l and ml / l and the analysis data is exported to AODN: https://portal.aodn.org.au.
