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

Premise 1.Premise 1.

Thorough 4-D examination of at least one plate/mesoscale system will generate new insights into all such systems.

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

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!
