Outline
• Science context• NEPTUNE – past, present, future• Power – Overview, Organization, Finances• The Concept Design Review (CoDR)• The Preliminary Design Review (PDR)
Many globally significant planetary phenomena operate at or below the scale of a tectonic plate

NEPTUNE Benefits to ResearchNEPTUNE 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

Science PlanningNEPTUNE 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
• 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

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
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
Project Organization
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, …
Concerns• Political
• Need science buy-in
• Management
• Technical risk
• Schedule and Cost
• Overall uncertainty in the project
• Technical
• Provide high-rel service
• Testing
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
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!
