The Canadian Integrated Ocean Observing System (CIOOS) is an open-access national system that brings together the various elements of ocean observation in Canada. It facilitates access to existing resources, new information, and technology and makes data discoverable.

CIOOS captures a selection of Essential Ocean Variables (EOVs) aligned with the Global Ocean Observing System (GOOS), contributing to global efforts of better understanding the ocean, marine issues, and interactions with other earth systems.

CIOOS is the result of a successful collaboration between various institutional and non-governmental partners located in the Pacific, the St. Lawrence, and the Atlantic.  Three Regional Associations (RAs) work closely with local oceanographic communities and organizations to meet the end-user needs. Ocean observations produced through regional networks are essential to effective ocean management. Therefore, the regional associations are actively engaged in their communities in collecting reliable and high-quality data and in continuously improving services offered by CIOOS to support evidence-based decision making.


Our mission is to improve national coordination and collaboration between diverse ocean data sources as well as improve the access and discoverability of information for better decision making. We provide support for a wide variety of economic sectors and research efforts to understand, monitor, and manage activities in the marine and coastal environments.


Our vision is to offer all Canadians a fully integrated and sustained online ocean observing system by maximizing access to data and information.


We believe in open access to reliable and high-quality data and information, in a productive and respectful partnership with different stakeholders and innovation and science-based and neutral policies. These values are embodied by the partners involved in CIOOS.
