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. 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 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 Infrastructure. Results from the AusCPR survey are available through the AODN portal: https://portal.aodn.org.au. 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.

Seabird and incidental cetacean and seal sightings were recorded during daylight hours during the transit from Sydney to Broome, Western Australia in March 2017 Observations were made every ten minutes in the forward quadrant. There were 657 observations from 30 species of birds, 1 cetacean, 5 seals and one turtle. The commonest bird species were Sterna anaethetus and Puffinus carneipes. Each species has been linked where possible to the World Register of Marine Species (WoRMS https://www.marinespecies.org). The data has been published to the Ocean Biodiversity Information System (OBIS https://obis.org).
