  1. Ocean Technology Test BedColin Bradley, University of Victoria John Roston, McGill University NEPTUNE Canada VENUS

  2. Objectives Design, deploy and evaluate multiple enabling technologies on an integrated test bed. • Research & develop enabling technologies. • Utilisation on an observatory system.

  3. VENUS Observatory • Deployment, Dec. ’05. • ROV mate connectors installed for OTTB. • OTTB power & comms feed through.

  4. Pat Bay Location • Node and cable lay in December. • High bandwidth connection to UVic & McGill to follow.

  5. OTTB Site Bathymetry • 100m depth. • Interesting features. • Relatively low risk site for technology evaluation.

  6. Ocean Technology Test Bed

  7. Underwater Vehicle Development • Tethered Vehicles • Autonomous Vehicles

  8. Tethered Vehicle (Canarie) • Develop an underwater case containing camera and hardware. • Integrate an underwater pan/tilt mechanism. • Modify a ROV to carry the HD camera package. • Power distribution system. • Use an ROV to deploy the video system package on the seafloor.

  9. Tethered Vehicle (Future) • Tethered to node - long duration. • Integrate with node – power and communications. • Tether management. • Science package. • Acoustics (later).

  10. Autonomous Vehicle

  11. Autonomous Vehicle Research • Hybrid – features of AUV and ROV. • Spatial sampling opportunities (science driver). • AUV docking system. • Power and data transfer (non-contact). • Integrate with acoustics.

  12. Integrated Acoustic System (Planned) • Positioning (triangulation) • Communication (low data rate)

  13. Acoustic System (Current Status) • Top side GPS buoys • Acoustic triangulation • Receiver on vehicle

  14. High Definition Imaging • Collaboration of the Instructional Multimedia Services and the Centre for Intelligent Machines. • Deliverable: underwater HD camera on the VENUS network transmitting live 720p60 format video over CA*net 4 to McGill. • Camera can be interactively controlled using web services.

  15. High Definition Imaging • Web Services software that can replicate remote camera control functions (eg auto white balance and auto iris). • Minimize latency of the HD video transmission to enable camera control input, such as zooming, in response to observed events. • Testing two UCLP software packages.

  16. Science + Enabling Technology • Sustained, long duration science programs. • Spatial sampling (return to same location). • Event driven measurement. • Integrated infrastructure that links all elements together. • Extends Internet connectivity to ocean floor.

  17. Science Programs • Exchange of material (nutrients) between sea floor and lower water column. • Imaging of organisms around node (bacterial mat) around. • Water sampling. • Profiling of water column (suite of sensors).
