Contributing to CIOOS Atlantic increases visibility for your data. Your organization can be a part of the open data community and increase access to information. Sharing your data with us encourages scientific collaboration, supports innovation, facilitates knowledge discovery, and more.
Atlantic Canadians share a deep connection to the ocean, and information about the ocean provides many benefits for our society and economy. CIOOS Atlantic is working to provide data not only to researchers and government agencies but also to a broad range of end-users, ranging from coastal communities to ocean industries, First Nations, and non-governmental organizations.

The Canadian Integrated Ocean Observing System (CIOOS) improves access and visibility to high quality ocean data and information. This is accomplished through our open-access platform that delivers observational and model data and associated metadata in a consistent format. CIOOS works to increase collaboration and coordination in the ocean observing community around the country while remaining regionally focused.
CIOOS benefits both data providers and consumers across the ocean community. Academics, government agencies, ocean industries, coastal and Indigenous communities, and non-governmental organizations are key target audiences for data management services. That said, all Canadians will benefit from improved data access for decision makers and the tools that are developed from turning those data into information and knowledge for all.
Yes! CIOOS has ongoing engagement and dialogue with Indigenous governments, organizations and communities. Together, we are exploring best practices for preservation of Indigenous ocean knowledge and data in ways that support Indigenous data sovereignty. CIOOS has adopted CARE (Collective benefit, Authority to control, Responsibility, and Ethics) Principles for Indigenous Data Governance. Contact us to become part of the conversation.
CIOOS works to address fragmented and isolated Canadian data by creating an open-access platform that facilitates discovery of previously inaccessible and undiscoverable data to end-users on a national scale. This integrated approach helps to coordinate the national management of ocean data and, critically, is adaptable in the face of growing needs and a changing environment. Furthermore, the improved coordination of regional and national efforts within CIOOS contributes to global ocean observing, maximizing the overall benefit of integrated observing.
CIOOS is primarily funded by Fisheries and Oceans Canada (DFO) and the Marine Environmental Observation and Prediction Network (MEOPAR). MEOPAR also hosts the CIOOS Coordination Office. We invite individuals, organizations, or businesses to contribute to CIOOS and join the collaboration. Be part of Canada’s ocean future and contact us ca for more information.
CIOOS is free for data consumers. Data providers should engage with your Regional Association to discuss your data holdings and to assess the steps for integration.
Training opportunities are in development. Join our mailing list to be among the first to know when they will be delivered!
