The Canadian Integrated Ocean Observing System (CIOOS) is an online open-access platform designed for sharing reliable and high-quality data and information on the state of our oceans. This nationally coordinated system brings together a consortium of partners in the Pacific, St. Lawrence, and Atlantic regions. Regional Associations (RAs) actively support ocean science and management as well as promote collaborative opportunities among ocean sectors across Canada. CIOOS responds to user needs enabling them to share, discover, access, visualize, and download data. Data are discoverable by clicking on the icons appearing on the asset map above, through the national catalogue or by accessing the catalogue and visualization tools available through the Regional Associations (RAs) websites.
