    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.

  • This record describes data from the BASTA cloud radar, collected on the Marine National Facility RV Investigator voyage IN2015_V01. This voyage departed Hobart on the 21st March and returned to Hobart on the 29th of March, 2015. The BASTA cloud radar is a vertically-pointing 95 GHz FM-CW (Frequency Modulation - Continuous Wave) radar. It measures vertical profiles of radar reflectivity (approximately proportional to the cloud particle diameter to the 4th power), and Doppler velocity (sum of vertical wind speed and terminal fall velocity of cloud particles when pointing vertically) at 1.5s temporal resolution, and four different vertical resolutions (12.5, 25, 100 and 200m) up to 12 km height. Currently the instrument is not mounted on a stabilized platform but will be in a near future. This cloud radar is owned by the Australian Bureau of Meteorology. It was developed by the Laboratoire ATmosphere, Milieux et Observations Spatiales (LATMOS) in France. It is serial number 2. Calibration of the cloud radar was performed in 2014 using fixed targets of known reflectivity, and reflectivity in light rain.
