Discover the ocean.Understand the planet.

Working for the advancement of science and the benefit of Canada.


Evidence-Based Decision Making

The state of the ocean is an important indicator of the overall health of the planet. The ocean off the coasts of Canada, including the Arctic, comprises some of the richest and most diverse ecosystems on Earth. This makes Ocean Networks Canada data relevant to global users.

Ocean exploration is as exciting and complex as traveling into outer space. It involves cool tech, hard science, daring innovation, and a large team of highly qualified personnel. And thanks to underwater cameras and telepresence technology, the public can participate in Ocean Networks Canada’s (ONC) quest to know the ocean. Starting on 28 April, Expedition 2017: Wiring the Abyss is ONC’s first major expedition of the year. This ten-day operation involves a team of 35 scientists, engineers, technicians, and data specialists who will live aboard the Canadian Coast Guard Vessel John P. Tully.

Understanding whether fish communicate using sound is of growing interest and importance. Although many fish species are soniferous⎯they naturally produce sounds⎯we know very little about how and why this happens. Among the approximately 400 known marine fish species swimming in British Columbia waters, only 22 have been reported to be soniferous, although many more species are suspected to produce sound.

Building a Smarter Ocean

Smart Ocean Systems™ operationalizes Ocean Networks Canada’s innovative technologies and expertise for the benefit of Canada and the world. Cabled observatories, remote control systems and interactive sensors, and big data management enable evidence-based decision-making on ocean management, disaster mitigation, and environmental protection.

As shrinking sea ice ushers in a new era for arctic tourism, Ocean Networks Canada’s (ONC) newly expanded Cambridge Bay observatory becomes a vital tool for monitoring ocean health and marine safety.

A small ONC team was in Cambridge Bay from 21-28 August, maintaining and upgrading the observatory and building relationships with the community. Stay tuned for an update on the recently expanded Arctic Ocean monitoring system.

In June 2016, Ocean Networks Canada (ONC) successfully deployed and connected the first of several earthquake early warning sensors on the Cascadia subduction zone. It will be part of a network of seismic sensors that ONC will install underwater and on land as part of an earthquake early warning system (EEWS) in partnership with Emergency Management British Columbia (EMBC).

Big Data. Big Solutions.

Long-term, continuous scientific data from the ocean environment are gathered by Ocean Networks Canada and made available through Oceans 2.0—a powerful online data management system. Oceans 2.0, combined with high-performance computing, allows ONC to provide ocean analytics that assist researchers, communities, industry, and policy-makers in making evidence-based decisions in Canada and globally.

With hundreds of instruments monitoring Canada’s marine environment, ONC gathers the same amount of data as the Hubble Telescope. Turning a firehose of high resolution data into useful knowledge is the challenge of the century. ONC’s robust and sophisticated data management system, Oceans 2.0, is already recognized as a state-of-the-art ocean management tool for marine decision-making, and it’s about to get even better.

It’s never too early to help young ocean scientists get to know the ocean. In April 2017, Ocean Networks Canada (ONC) hosted its fifth annual Ocean Science Symposium, an engaging two-day opportunity to inspire the next generation of ocean scientists. Bringing together over 70 students and teachers from 16 schools across Vancouver Island, northern British Columbia, and the Arctic, this educational hands-on experience emphasized the teamwork and collaboration needed to explore and understand the ocean.

In a banner year for Canada, when science and state are more aligned than ever before, we owe our future generations the courtesy of protecting the natural wonder of our North by shining a light on its limitations before pursuing its opportunities. If we don’t act soon, we risk losing control over a defining piece of our 150-year identity that is melting away before our very eyes into the pages of history.

The Great Thaw: our melting Arctic must be monitored and Canada should lead the way
