Shore Stations, Submarine Cables, Nodes, Instrument Systems

Ocean Networks Canada installations are helping to monitor, study, and better understand our coastal marine environment. The on-site infrastructure consists of shore stations, armoured submarine cables, observatory nodes and connected observatory instrument systems.

  • Shore stations provide high voltage DC current to the node and instruments via a copper conductor, and Ethernet communications via optic fibres, both housed in an armoured marine telecommunications rated cable.
  • Node and instrument systems are large multi-ton platforms, housing pressure cans and delicate scientific instruments.

Cable corridors and instrument sites have been cordoned off for network use though regulatory permits. We appreciate your cooperation in avoiding these areas. Although most gear is mounted on the bottom, there are mid-water column moorings and surfacing profilers connected to the network in Saanich Inlet, Barkley Canyon and the Juan de Fuca Strait.

Our cable routes and instrument coordinates are available in the downloads section at right. If other formats or information are required, please contact us via this form.
