VENUS & NEPTUNE

DMAS Progress Report

what is venus
What is VENUS?
  • Shallow-water test bed for NEPTUNE
  • But more than just engineering (lots of science topics)
  • Easy access (Saanich Inlet and Strait of Georgia)
  • Financed at ~10 MCAD
venus project status
Data line to hi-speed cable

Venus line landing in instrument shack

Institute of Ocean Sciences - DFO

VENUS Project Status
  • Saanich Inlet wet plant installation end of September
    • Shore station near IOS (in a DND building!)
    • About 6-7 different types of instruments initially
    • Test bed for HDTV camera
    • Data backhaul 100Mb/s to UVic (budgeted), internet; seeking DF
  • Strait of Georgia line in 2006
what is neptune
What is NEPTUNE?
  • International Project
    • ~250 MCAD, 30% Canada-70% US, but ∆T ≥ 3 years
    • Inter-operability between the two stages
  • NEPTUNE Canada: First of its kind RCO
    • ~5 nodes, 100’s instruments, 24/7 ops, 100kW power, ~8Gb/s, 2500m depth, >25 years lifetime
  • Themes
    • Science: geology (seismic, tsunamis), gas hydrates, climate, biology
    • Engineering: power, lifetime, uninterrupted operation, internet in the Ocean, data storage & distribution
neptune project status
NEPTUNE Project Status
  • Wet Plant:
    • Selection of main contractor for wet plant on-going (BAFO expected soon)
    • Decision in June, contract in July
    • Installation in Q2/Q3 ‘07 with a few test instruments
    • Shore station in Port Alberni, BC
    • ~40 MCAD available
  • Instrumentation:
    • Selection of science instrumentation programs on-going
    • Most installed in ‘08
    • ~13 MCAD available

DMAS
  • DMAS has four elements:
    • Data acquisition & archival
    • User data access, selection and retrieval (implementation of observatory data access policy)
    • Instrument control (exploitation of various instrument modes)
    • Observatory monitoring, resource management (power & bandwidth)
    • Budget ~7 MCAD
dmas status
DMAS status
  • Prototype system with data acquisition, archival, data retrieval completed in February
  • Prototype currently being adapted for VENUS use (DB redesigned), will evolve with time
  • Systems, DB Administrator and one software developer recruited
  • VENUS core hardware & software received

Resource Management

a few design constraints
A few design constraints
  • DMAS shall implement the data access policy of the observatory
  • DMAS shall allow users to know about its capabilities (resource discovery)
  • DMAS shall as much as possible provide users with data in physical units.
  • Backhaul line may not have the same capacity or reliability as the underwater network
dmas status1
DMAS Status
  • Budget Issue:
    • Wet plant funds short due to NRE costs not shared with US partner
    • Savings possibly required from both science instruments and DMAS
    • Trying to compensate shortfall with responses to call for funding proposals
      • GEOIDE: ~120KCAD requested for warehouse products evaluation
      • CANARIE: ~2.3MCAD project on Service Oriented Architecture and workflow management (sensor and archive access through WS, workflow for event management) for DMAS. (With IBM Canada).
      • CANARIE: ~1.1MCAD project on sub-sea HDTV camera control and data transfer using WS and UCLP
dmas conceptual design
DMAS Conceptual Design
  • System architecture to map wet plant structure:
    • Extend the Internet into the ocean: tree structure, DNS
    • Shore station ≠ Data center  backhaul  need for buffering @ shore
  • Initial software development limited to:
    • Interfaces with instruments (instrument drivers)
    • Data subscription (mostly for streaming instruments)
  • All other elements are from the public domain or off-the-shelf commercial products
  • Novel approaches to data access (Service-Oriented Architecture)
  • Use of workflow tools for preparation of event detection recipes

dmas operations
DMAS Operations
  • Ops & data center at UVic (not at shore station)
  • Shore station mostly unmanned, remotely monitored
  • Data on-line backup elsewhere on campus for VENUS, (in WA/OR for NEPTUNE?)
  • Three types of users:
    • Public  access to “pre-cooked” products (images, plots, …)
    • General scientist  access to quasi-live or historical data through thin (web browser), special-purpose middleware (e.g., MATLAB with web and DB i/f) or fat clients (data analysis packages with WS access)
    • PIs  direct access to own instrument for live access, through shore station (bypassing data center).
expected usage of neptune venus
Expected Usage of NEPTUNE/VENUS
  • Some limited direct interaction to take place:
    • Occasional control of moveable instruments: cameras, ROVs
    • Restricted to instrument PI or their team members
    • But humans typically available only 8 hrs/day!
  • Expected long-term use mostly through automated event detection and scripted routine maneuvers:
    • Value checks against hard-coded thresholds or the instrument’s own long-term trends or correlation of multiple instruments outputs
    • Reactions as commands to e.g., turn on cameras and lights when “something” is detected
    • Reactions contingent to other phenomena: e.g., activate water column profiler winch when water current strength small enough
    • Automated extraction from video and audio stream, populating “content databases” that can subsequently be searched (e.g., instantaneous fish count in still images or video)
network issues
Network Issues
  • VENUS “Last Mile”
    • Wet plant capacity will be 1Gb/s.
  • NEPTUNE “Last Mile”
    • Wet plant capacity ~8Gb/s
  • Solutions?
    • VENUS dark fiber shore station access probably covered by a CANARIE grant (waiting for announcement)
    • NEPTUNE needs to apply to CANARIE for support to get dark fiber
networking issues
Networking Issues
  • Access security
    • Protect assets  authentication, authorizations
    • US Navy, DND requests: remote access to shore station: re-direction of data flows at specific times
conclusions
Conclusions
  • VENUS & NEPTUNE development progressing
  • Projects are exciting from a scientific, technological and education/outreach point of view
  • Need to convince science community to change its approach towards doing ocean science: exploit the power!
