and the Australian Antarctic Division, DEWHA, to monitor plankton communities as a guide to the health of Australia's oceans. Plankton respond rapidly to changes in the ocean environment compared to other marine animals such as fish, birds and mammals, which makes them ideal biological indicators of ecosystem change. AusCPR was initiated in 2007 and funding has been secured initially for four years, although it is envisaged that the survey will continue well into the future. The aims of the AusCPR survey are to: * map plankton biodiversity and distribution * develop the first long-term

. This survey is one of the longest running marine biological surveys in the world, and many climate related changes in the plankton have been observed over the past 70 years. The design of the CPR has remained fundamentally unchanged over time as the simple yet robust design is a key to its success as an effective plankton sampler. The key to its success as a frequent basin-scale sampler is that the device is towed behind ships of opportunity (SOOPs) unaccompanied by scientists or research staff, making it a cost-effective sampling platform. The CPR is towed at about 10 metres below the surface and for about 450 nautical miles (830 km) per ‘tow’. The plankton enters a small opening in the device and is trapped and preserved between two layers of silk mesh. In the laboratory the silk is unrolled and phytoplankton and zooplankton are counted and identified. Data generated by the survey will be made freely available according to the Integrated Marine Observing System (IMOS)] data policy and will provide researchers and policy makers with environmental and climatic indicators on harmful algal blooms, eutrophication, pollution, climate change and fisheries. The AusCPR survey will collaborate with sister surveys, the SCAR Southern Ocean Continuous Plankton Recorder Survey and the
