The Canadian Integrated Ocean Observing System (CIOOS) was established in 2019 to address inaccessible ocean data and the lack of a mechanism for coordination and collaboration in Canada’s ocean observing community. CIOOS works to integrate fragmented and isolated ocean data by creating an open-access national platform that facilitates data discovery for end-users.

CIOOS curates Essential Ocean Variables (EOVs) collected in Canadian waters aligned with the Global Ocean Observing System (GOOS). Our efforts contribute to global initiatives and are part of Canada’s commitment to the United Nations Decade of Ocean Science for Sustainable Development (2021 – 2030). These endeavours strive to make ocean science more accessible, predictable, and engaging for all. 

CIOOS is a collaboration between institutional, governmental, and non-governmental partners located in the Pacific, the St. Lawrence, and the Atlantic. These Regional Associations (RAs) work closely with local organizations to meet end-user needs and develop place-based solutions for a diverse country.

We acknowledge and respect the First Nations, Metis, and Inuit peoples on whose traditional territories CIOOS work is conducted. We strive for respectful relationships with all Indigneous peoples as we search for collective healing, true reconciliation, and honouring these beautiful lands and seas together.


As Canada’s nucleus for ocean observing, CIOOS makes connections for a sustainable ocean future.


To foster partnerships and grow a powerful online platform that generates information, knowledge, and place-based solutions to advance our understanding of the ocean.
