The Canadian Integrated Ocean Observing System (CIOOS) is Canada’s nucleus for integrated ocean science and observing activities.

CIOOS engages locally, connects regionally, and coordinates nationally to elevate Canada’s ocean monitoring to the global stage. These partnerships generate information and facilitate place-based solutions to advance our understanding of the ocean. With CIOOS, users can now discover, access, and visualize high-quality data through our online platform. By navigating these vast waters together, CIOOS helps prepare for Canada’s future by unlocking the true potential of our ocean, coasts, and waterways. 

What discoveries can be made if we just connect the dots?
