Technical and Operating Requirements
James Ryan, Marine Institute
DCU Feb 11th 2009
2

• SmartBay is a Test and Demonstration Platform for
  Advanced Sensing Technologies
• 2 over-arching requirements
• To provide test facilities for new sensing
  systems and associated technologies
• To demonstrate to potential participants and
  emerging markets the usefulness and feasibility
  of the observatory approach to understanding
  coastal environments

• Test Facility Requirements
• Versatility in terms of sensor systems which can
  be accommodated
• Broad range of power and data transmission
  options
• Wireless and cabled sensor nodes
• Solar panels or up to kilowatts
• Fibre or wireless comms
• Dedicated test nodes as well as nodes just for
  sensing

• Test Facility Requirements
• The test nodes should be accessible from the
  following perspectives
• IT infrastructure
• Power supply
• Convenience of road and public transport access
• Site for shore station available
• Proximity to all-tide pier
• Scuba access to sea bed components where
  possible (20m max depth)
• Shelter from wave action

• Test Facility Requirements
• The test nodes should be simple and
  straight-forward for users to operate e.g.
• Service by local workboat
• SCUBA or occasional ROV

• Demonstration Requirements
• It must actually work!
• maximise use of proven off-the- shelf components
• It must be affordable
• Off-the-shelf as in (a) above
• DIY approach (Not Big Telecom!)
• It must be simple to operate (as for test
  facility requirements)

• Demonstration Requirements
• It must actually do something demonstrably
  useful
• Accurate portrayal (and forecasting) of key
  processes in Galway Bay
• Sensor nodes should be optimally located for
  monitoring key Bay processes
• Some sensor nodes should be located in areas of
  environmental variability (e.g. fresh water
  ingress) and maximum human impact (e.g.
  pollution)

• Other Requirements
• The need to minimise impact on other
  stakeholders, primarily
• Shipping
• Fishermen
• Conservation interests
• Where possible locate cables and buoys away from
  shipping routes, trawling or dredging ground
• Consult with conservation interests

• 3 Categories of Sensor
• Core sensors for monitoring key Bay processes
• Conductivity, temperature, depth
• Fluorescence
• Dissolved oxygen
• Novel sensors
• Project sensors e.g. pCO2, dolphins etc

15
The VENUS Proposal

• Three arrays with multiple nodes, each supporting
  a wide range of instruments in depths to 300m
• Kilowatts of power available at each node
• Ethernet architecture to the instrument
• Near real-time data access using web delivery
• 20 year life for project and data archive
• 10M Can (8M cash with 2M in-kind)
