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.

Pere Puig

Ocean Networks Canada visiting scientist Pere Puig is a marine geologist whose expertise in deep sea sediment dynamics is contributing to our growing understanding of the importance of submarine canyons. And, as the grandson of a shrimp fisherman in northern Spain, Pere’s research is also having a direct influence on Mediterranean fishing practices.

Salish sea Map

Victoria is infamous for its practice of discharging screened, but otherwise untreated, municipal sewage into Juan de Fuca Strait. Starting in early 2013, Ocean Networks Canada (ONC) has been partnering with Victoria’s Capital Regional District to help measure the impacts of their outfalls on the local marine environment.​

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.

Cambridge Bay annual maintenance team

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.

Earthquake Data



Ocean Networks Canada seafloor and land-based sensors recorded a magnitude 4.8 earthquake in the Strait of Georgia, just before midnight on 29 December.​

South coast communities feel the shake!

Undergraduate student, Ada Loewen, just completed her co-op term at Ocean Networks Canada (ONC) as part of her combined University of Victoria degree in physics and ocean sciences. Using data from the Cambridge Bay observatory, Ada improved a one-dimensional thermodynamic sea-ice model funded through ONC’s Safe Passage project with Polar Knowledge Canada.

Minister Aldag makes CANARIE funding announcement

An investment of $577,000 has been made by CANARIE to enhance access to and processing of big data collected by Ocean Networks Canada (ONC). ONC’s cabled ocean observatories support hundreds of underwater and on-land sensors that generate a huge volume of continuous, high-resolution data about the ocean.
