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

  2. 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

  3. 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)

  4. Huon Surface node Underwater node TasMAN • Sensor locations • CSIRO Wharf • Derwent mouth • Mid-Derwent • North-West Bay • Huon • Storm Bay • Temp & Salinity initially • Turbidity/ Dissolved O2 / Fluorescence later Derwent Derwent D’EntrecasteauxChannel D’EntrecasteauxChannel Huon Deployed node Planned node

  5. Sensor Cluster – Mouth of the Derwent high gain (7 dBi)antenna acoustic modem with batteries and Fleck SeaBirdSBE-37 sensor mooring chain pycnocline inductive cable withattached sensors mooring acousticrelease

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

  7. 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

  8. Mobile sensor nodes

  9. CSIRO Autonomous Underwater Vehicle • • Now at third generation • • Starbug research focus • • Vision-based navigation & control • • Autonomy • • Cooperative robotics • • Human robot interface • • 3D visualisation • • Robot sensor network interaction • • Starbug specifications • • Mass: 26kg • • Length: 1.2 m • • Propulsion: 5 thrusters • • Endurance: 12 hrs @ 0.6m/s • • Sensors: 4 cameras, pressure, GPS

  10. Autonomous Data Collection
