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.

During this 2-week expedition aboard the Canadian Coast Guard Vessel John P. Tully, a team of 17 scientists, engineers, technicians and data specialists will conduct operations to maintain, install and improve infrastructure and instrumentation on ONC's cabled observing networks, with the support of Pelagic Research Services ROV Odysseus.

Ocean Networks Canada will receive a $7.2 million boost to advance its ocean observatory science and technology activities, the Canada Foundation for Innovation announced today.

Funding boost helps advance ocean intelligence

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.

Our first artist-in-residence program was an exciting, innovative and fruitful venture that helps the public understand and engage with ocean data in the Salish Sea and Fraser Delta. Visual artist and University of Victoria alum Colton Hash recently completed a six-month residency working with Ocean Networks Canada scientists and data specialists to create artistic visualizations from ocean data.
