Maintenance and Update Frequency: asNeeded Statement: Data sampling is being conducted as part of a larger IMOS monitoring program. The silk is removed from the CPR cassette and processed as described in Richardson et al 2006. The phytoplankton colour index (PCI) and the phytoplankton data are also analysed as per Richardson et al 2006. The zooplankton analysis is conducted differently to that described in Richardson et al 2006 as it is counted off the silk in a bogorov tray. This is accomplished by rinsing the silks in water and straining through a 10 micron mesh sieve. The collected plankton is transferred to a bogorov tray and counted under a disecting scope. This is done to retain the phytoplankton. AusCPR decided to analyse the zooplankton this way as it provides a more accurate analysis of the zooplankton present. It is easy to miss zooplankton when it is still on the silk and it is harder to identify. After counting the zooplankton and phytoplankton are transferred onto a preweighed filter and dried in an oven at 60 degrees C for 24-48 hours. Once dried the sample is reweighed to attain dry weight. Statement: ATTRIBUTE STATEMENT: Route_Code - Unique code for the sampling route (Start/End Port) Longitude - Longitude of sample (Decimal degrees, WSG84 datum) Latitude - Latitude of sample (Decimal degrees, WSG84 datum) Sample_date_UTC - Time of sample (Coordinated Universal Time) Species / Genus / Higher taxonomic group - Phytoplankton taxonomic species information Taxon_Per_m3 - Derived estimate of phytoplankton abundance (number per cubic metre) Statement: Originally this collection only provided the raw data in flat table form (with each species recorded in a separate row). When the "analysis-ready" products were first published (on 21/12/2018), the flat tables were removed as they were considered obsolete. Since the products are now out of date (last updated August 2019), on 2/11/2020 the flat tables were made available again, and are updated weekly with the latest data. In April 2021, access to the ...
