NEPTUNE-Canada (North-East Pacific Time-series Undersea Networked Experiments) is the world′s first regional-scale cabled ocean observatory on the northern Juan de Fuca tectonic plate in the north-east Pacific, and offers unprecedented opportunities for all researchers involved in the ocean and earth sciences. Major research themes of NEPTUNE-Canada are focused on earthquakes and plate tectonics, fluid flow in the seabed, marine processes and climate change, and deep-sea ecosystems.  NEPTUNE-Canada is characterized by abundant power, high bandwidth communications and hundreds of sensors. This network connects directly Internet and delivers underwater data and imagery in real or near real time via high-speed optical fiber -optic communications.
