Installation Operation

• Traditional fibre optic submarine
  telecommunication cable
• Cable across the continental shelf will be buried
  where possible
• Experiments will be connected to observatory
  nodes
• Observing systems will be manipulated and
  monitored by scientists around the world
• Public access to 30-year data bank of
  observations
• Increase understanding of the ocean environment

NEPTUNE Stage I Route Survey Vancouver Island
Shelf
23
Conducted continental shelf geophysical work to
define route Completed surveys using an
Autonomous Underwater Vehicle (AUV) near the
Endeavour Ridge Obtained seabed information as
part of the cable burial assessment process
across the continental shelf and slope off
Vancouver Island Obtained Multibeam Echosounding
data across the abyssal plain between the
continental margin and the Endeavour
Ridge Further defined the science experiments to
be carried out in the vicinity of Barkley Canyon
and at the Endeavour Ridge

Next Steps

• Carry out continental slope surveys in 2006
• Design, develop and test instrumentation for
  scientific experiments
• Design and construct cable and nodes
• Develop Data Management and Archival System
  (DMAS)
• Install network in 2007 with some instruments
• Install remainder of instruments in 2008
