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


Venus neptune

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

VENUS DMAS schedule

Data Ingest

Basic Query i/f

Instrument Commanding

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

Venus instruments

VENUS Instruments

  • First Array: (Saanich inlet)

    • 3 types of CTDs (one with Oxygen sensor)

    • ADCP

    • ZAP (vertical and horizontal)

    • 8MPix moveable digital still camera

    • 3-way hydrophone array

    • HDTV camera

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!
