Real-time Monitoring of the Derwent and Huon Estuaries in Southern Tasmania Greg Timms Senior Research Scientist Tasmanian ICT Centre, CSIRO 20 May 2009 Wealth from Oceans

The Tasmanian Marine Analysis Network (TasMAN) Collecting and integrating real-time data to support multiple uses of the Derwent/Huon/Channel Region in southern Tasmania The role of the Tasmanian ICT Centre Present existing data in a standard format/interface Set up infrastructure/communications to enable real-time data collection from the region New data collection technologies Data management and streaming data processing (e.g. event detection) Integration of data with CSIRO models for forecasting Data visualisation Current partners/data providers/stakeholders HydroTas Bureau of Meteorology IMOS CSIRO Marine and Atmospheric Research

The role of sensor networks Provide the ability to collect real- time and near real-time data Automated collection Enables quick response to events Monitor recovery Limits costs and liabilities Enables reliable short-term forecasts (when coupled with models)

Fixed automated sensors Time series data, single location Real-time comms (Radio, Acoustic, Satellite, 3G phone) or loggers

Fixed automated sensors - challenges Security (particularly in coastal and estuarine environments) Physical damage (waves, wind, etc) Permissions Cost – $3k up to $150k+ Deployment/maintenance Biofouling
