Preliminary Design Review Bruce M. Howe Applied Physics Laboratory, University of Washington University of Washington 4 – 5 December 2003

Slide4: 

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

NEPTUNE: 

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

Science Topics: 

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

Slide8: 

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

Slide9: 

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

Slide10: 

• 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

Slide11: 

Cabled Regional Observatory Essential Elements

Slide12: 

Sensor Networks

Slide13: 

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

NEPTUNE Phase 2 Partners: 

NEPTUNE Phase 2 Partners Canada – University of Victoria University of Washington Woods Hole Oceanographic Institution Monterey Bay Aquarium Research Institute Jet Propulsion Laboratory

NEPTUNE MANANAGEMENT: OVERVIEW PROGRAM OFFICE (COORDINATION, FUNDING, ADMIN, LEGAL, FINANCIAL, PUBLICITY) OUTREACH TEAM CHAIR: To be selected MEMBERSHIP: LEADERS OF INDIVIDUAL OUTREACH GROUPS ENGINEERING TEAM PROJECT MANAGER: PATRICIA BEAUCHAMP MEMBERSHIP: MANAGERS OF INDIVIDUAL IMPLEMENTATION GROUPS PROGRAM DIRECTOR CHAIR, EXECUTIVE TEAM JOHN R. DELANEY BOARD OF GOVERNORS Member Institutions TBD Note: NEPTUNE will involve SPONSORS, BUILDERS, AND USERS. This chart reflects the organization of the builders only. Goal: To manage the overall NEPTUNE program and ensure participation of all interested scientists, educators, and members of the general public. Vice Chair – Chris Barnes ADVISORY BOARD TBD MOU completed 5/’02

Slide16: 

NEPTUNE - past Scientific Uses of Undersea Cables Workshops – 1990, 1997, 2003 – new and retired systems NOPP proposal 1998 UW $2M – feasibility study, report 6/’00 Emerald Lake Meeting – organize – 9/’00 NSF Comms - $2M – WHOI, 10/’00 Keck proto-NEPTUNE $5M – UW et al., 7/’01 NSF Power - $2M – UW and JPL, 10/’01 (5/’02) NOPP proposal 5/’01 – SE, Sci, ProjOff, funds 4/’02, $1.7M

NEPTUNE Schedule Phase 1 - Feasibility Studies 1998 – 2000 Phase 2 - Development 2000 – 2005 Plan/Design Test beds 2003 – 2006 MARS Installation 2005 Canadian Funding! 2003 US MRE Proposal 2005 Phase 3 - Deployment MRE, Procurement Begins 2006 Installation 2007 – 2009 Phase 4 - Operations 2008 – 2038+

Slide23: 

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

Slide24: 

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

Slide26: 

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, …

Slide27: 

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

Slide28: 

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

Slide29: 

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!
