The NRSs are designed to provide regular baseline information to understand how large-scale, long-term change and variability in the global ocean are affecting Australia s coastal ecosystems. The goal is to develop multi-decadal time series of the physical and biogeochemical properties of Australia s coastal seas, informing research into ocean change, climate variability, ocean circulation and ecosystem responses. The Rottnest Island NRS is sited at an historical mooring, operating since 1951 to monitor variability in the Leeuwin Current. This dataset contains seasonal data on zooplankton biomass and species composition collected since December 2009, using a 100 micron mesh drop-net deployed to 45 metres. The corresponding biogeochemical datasets include temperature, salinity, nutrients, Chlorophyll and phytoplankton abundance are available through the IMOS portal. These data from the Australian Continuous Plankton Recorder (AusCPR) survey and the Australia National Mooring Network (ANMN), both part of the Integrated Marine Observing System (IMOS) - IMOS is supported by the Australian Government through the National Collaborative Research Infrastructure Strategy and the Super Science Initiative.
