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 contains the processed Conductivity-Temperature-Depth (CTD) data collected on Aurora Australis voyage 1 and 1.1 1991-92. The voyage(s) took place in the Southern Ocean during September-October 1991 along the WOCE SR3 transect from Tasmania to Dibble Ice Tongue, Antarctica. This dataset is archived within the CSIRO Marine and Atmospheric Research Data Centre in Hobart. Additional datasets from this voyage are held by the Australian Antarctic Division, for which information is available via the Antarctic Division metadata system. The WOCE section data are also available via the WOCE website (see data links).

Phytoplankton Colour Index (PCI) After the silk has been marked into 5 nautical mile samples but prior to cutting, each sample is visually assigned a greenness index by comparison with standard colour charts: viz. no colour, very pale green, pale green, and green. These four levels of the phytoplankton colour index (PCI) represent the amount of phytoplankton pigment on the silk and have been assigned numerical values on a ratio scale based on acetone extracts using spectrophotometric methods.

AusCPR: Phytoplankton Abundance. 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 phytoplankton abundance data are analysed as per Richardson et al 2006. Phytoplankton are usually counted from water samples after settling but in the CPR analysis we count the phytoplankton in situ. With CPR samples, the phytoplankton is captured by the mesh and are caught by the silk strands, by phytoplankton mucilage, and/or by other organisms on the silk. It is thus possible to see the phytoplankton cells directly on the mesh. In essence, the phytoplankton is already concentrated. Washing the phytoplankton off the silks to count in the standard manner may result in loss of or damage to cells before analysis. It is advised that anyone using the data should first read this methodology or 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.
