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. Additional information for this dataset may be available via the original MarLIN metadata entry: https://marlin.csiro.au/geonetwork/srv/eng/catalog.search#/metadata/dfef238f-db69-3868-e043-08114f8c8a94. For information on using the data please refer to Eriksen et al. 2019. It is advised that anyone using this data should read this methodology or contact the project contact person. The data are made available in binned products for ease of use. As taxonomy changes over time and the ability of analysts improves with training more and more species are able to be identified over time. The products account for these changes and for real absences from the samples. A 0 abundance means that the species was looked for and not seen, -999 means that the species was not looked for in that sample. The products are therefore applicable for use in time series analysis. There are 4 products to choose from: Raw product (includes all data); Species product (includes all data where species have been identified); Genus product (includes all data binned to genus level); Higher taxonomic group (includes all data binned to functional groups). The binned and pivoted products described are currently only available by contacting imos-plankton@csiro.au. A project to make these products available directly via the portal is under way. This collection currently only provides direct access to the raw data in flat table form (separate row for each taxon in each sample). **All files are available in bio-volume instead of abundance on request.** **This dataset has been superseded by the IMOS - Phytoplankton Abundance and Biovolume (reference stations) collection that is available at https://catalogue-imos.aodn.org.au/geonetwork/srv/api/records/f098f0d0-88ac-4f4b-addb-24b3e5e8d0b9 (this collection was removed from the AODN Portal in December 2021).**Maintenance and Update Frequency: asNeededStatement: 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 Marine and Atmospheric Research, Queensland. 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 cyclinder and left to settle for 24 hours. Once settled the top 90 ml is siphoned off from these samples and the remainder is transfered 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 sqaures on the Sedgwick rafter. These counts are then converted to cells / l and ml / l and the analysis data is exported to IMOS.Statement: ATTRIBUTE STATEMENT: NRS_CODE - Unique identifier for the sample STATION_NAME - Sampling Station Name SAMPLE_DATE - Date of sample (day resolution) LONGITUDE - Longitude of sample (Decimal degrees, WSG84 datum) LATITUDE - Latitude of sample (Decimal degrees, WSG84 datum) TAXON_NAME - Taxonomic species information FAMILY - Taxonomic Family (where identified to Family) GENUS_NAME - Taxonomic Genus (where identified to Genus) SPECIES_NAME - Taxonomic Genus (where identified to Species) TAXON_ECO_GROUP - Taxonomic functional group CAAB_CODE - CSIRO unique identifier TAXON_START_DATE - Date from which this taxonomic entity was identified in this data set CELL_PER_LITRE - Calculated phytoplankton abundance for the sample BIOVOLUME_UM3_PER_L - Calculated phytoplankton biovolume for the sample SAMPLE_COMMENTS - Any comment relevant to the sampleStatement: Originally this collection only provided the raw data in flat table form (with each species recorded in a separate row).

These data are from the National Mooring Network, part of the Australia’s Integrated Marine Observing System (IMOS) is enabled by the National Collaborative Research Infrastructure Strategy (NCRIS). It is operated by a consortium of institutions as an unincorporated joint venture, with the University of Tasmania as Lead Agent. Each NRS collects its own zooplankton samples and sends them to the Queensland CMAR laboratories for analysis.
