AusCPR: Zooplankton Abundance The Australian Continuous Plankton Recorder (AusCPR) survey is a joint project of CSIRO Marine and Atmospheric Research (CMAR) and the Australian Antarctic Division (AAD) to measure plankton communities as a guide to the health of Australia’s oceans. 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. After counting the zooplankton and phytoplankton are stored with the silk segment in PGP preservative. 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. 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 CMAR laboratories in Queensland 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 eMarine Information Infrastructure (eMII). Results from the AusCPR survey are available through the IMOS data portal: http://imos.aodn.org.au/webportal/ For information on using the data please refer to the Richardson et al. 2006. 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. This data is freely available but please acknowledge all relevant parties, as detailed in acknowledgement section.

Study Extent
-10.0 N, 105.0 E, 175.0 E, -65.0 SSampling
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. After counting the zooplankton and phytoplankton are stored with the silk segment in PGP preservative. 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.Method steps
