The Australian Continuous Plankton Recorder (AusCPR) survey is a joint project between CSIRO Oceans and Atmosphere (O&A) and the Australian Antarctic Division (AAD) to measure plankton communities as a guide to the health of Australia's oceans. The biomass is analysed from the same segment from which the zooplankton is analysed. All the plankton is washed onto a pre-weighed filter. This is left in an oven at 60 degrees C for 24-48 hours. It is reweighed to give the dry weight. It is advised that anyone using the data should contact the project contact person. The aims of the AusCPR survey are to: * map plankton biodiversity and distribution * develop the first long-term plankton baseline for Australian waters * document plankton changes in response to climate change * provide indices for fisheries management * detect harmful algal blooms * validate satellite remote sensing * initialise and test ecosystem models. Servicing and maintenance of the CPRs and analysis of the samples for the AusCPR survey will be carried out by staff based at the O&A CSIRO laboratories in Queensland and Hobart and at the AAD in Hobart. The project was funded by the Integrated Marine Observing System (IMOS) and falls with the Ships of Opportunity facility. Data storage and access is planned to be interoperable with other national and international programs through the IMOS Infrastructure. Results from the AusCPR survey are available through the AODN portal: https://portal.aodn.org.au.

**This dataset has been superseded by the "IMOS - Zooplankton Abundance and Biomass Index (CPR)" collection that is available at https://catalogue-imos.aodn.org.au/geonetwork/srv/api/records/bf287dfe-9ce4-4969-9c59-51c39ea4d011 (this collection was removed from the AODN Portal in March 2022).**

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 dissecting 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.
These data are from the Australian Continuous Plankton Recorder (AusCPR) survey 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.
