4. Outline Science context NEPTUNE – past, present, future Power – Overview, Organization, Finances The Concept Design Review (CoDR) The Preliminary Design Review (PDR)

5. Many globally significant planetary phenomena operate at or below the scale of a tectonic plate Premise 1. Thorough 4-D examination of at least one plate/mesoscale system will generate new insights into all such systems. Premise 2. Understanding these systems will require decadal commitments Premise 3. NEPTUNE

7. Science Topics Ridge crest processes - volcanism, microbiology Seafloor hydrogeology and biogeochemistry Long-term ecological studies Water column physics / chemistry / biology Fisheries Seismology and geodynamics Subduction zone gas releases; methane clathrates Sediment flux from the continents to the deep sea

8. NEPTUNE Benefits to Research  New approaches lead to new discoveries  Limits to life / Origin of life  Ocean productivity in an area of strong gradients  Ecology and population dynamics of marine mammals and fish stocks  Dynamics of an entire lithospheric plate  Oceanic behavior of greenhouse gases  Integrated physics/chemistry/biology and models  Enhanced education and public awareness of research  New approaches lead to new discoveries  Limits to life / Origin of life  Ocean productivity in an area of strong gradients  Ecology and population dynamics of marine mammals and fish stocks  Dynamics of an entire lithospheric plate  Oceanic behavior of greenhouse gases  Integrated physics/chemistry/biology and models  Enhanced education and public awareness of research

9. Science Planning NEPTUNE PNW Workshop 23-24 April 2003 Recommendations: Cover shelf to abyss Coarse array of basic sensors integral part Begin sensor array designs now Cost models Data management key Clarify NSF funding plan PNW

10. Tectonic plate scale Lots of power (100 kW) Bandwidth (Gbits/sec) Real-time data return & control Robust design; high reliability Available for 20 - 30 years Key Characteristics of NEPTUNE

11. Cabled Regional Observatory Essential Elements

12. Sensor Networks

13. Long-term Issues  SENSORS and NEW APPROACHES  Sensor network infrastructure:  moorings/boreholes/distance/observatories  small diameter cables  underwater ROV-mateable connectors  AUVs and Rovers - docks/tethers/navigation/comms  Research ship and ROV capabilities  SENSORS and NEW APPROACHES  Sensor network infrastructure:  moorings/boreholes/distance/observatories  small diameter cables  underwater ROV-mateable connectors  AUVs and Rovers - docks/tethers/navigation/comms  Research ship and ROV capabilities

Power Users Electronics – transducers, computers, communications Motion – tethered, swimming, and bottom roving vehicles, active acoustics, pumping of fluids, battery charging Heat transfer – freeze specimens, cool electronics, heaters for chemistry and biology, anti-fouling Lights – Video – 500 W to 5 kW (IMAX 70 m), lasers System –  losses, infrastructure

24. Power System Design Primary design objective: Reliable delivery of stable power. Requirements (vague) – up to 10 kW at each node About 100 kW total average High Availability Main constraint – COTS telecom cable 0.7 – 1.0  /km Present effort: existence proof, demonstration of essential elements, MARS deliverables

25. Project Organization

26. Finances Present sources of Funding Internal NOPP (National Ocean Partnership Program) NSF (National Science Foundation) Original grant + MARS Total to date - $3M; balance is $900k Need additional funding Canadian CFI/BCKDF (~$725k) NSF, …

27. Concerns Political Need science buy-in Management Technical risk Schedule and Cost Overall uncertainty in the project Technical Provide high-rel service Testing

28. The CoDR Was first formal technical review of any aspect of NEPTUNE The power system is a new development = risk Concept was found acceptable by Board

29. The PDR Is the second formal review of NEPTUNE Power Will assess requirements, and whether we meet them Will assess approach, and whether we will succeed “preliminary” for MARS, “peer” for NEPTUNE BE CRITICAL!
