Argo is the largest ocean climate monitoring system in the world. It is an array of over 3,500 free-drifting floats that collects data on ocean temperature and salinity, providing valuable information on changes to the Earth's climate and hydrological cycle.
Fisheries and Oceans Canada is proud to be a strong contributor to the international Argo project. Since 2001, the department has launched 340 Argo floats, 100 of which are still operating.
Argo data is publically available for free and is used for a variety of purposes such as assessing climate change, improving weather forecasts and developing ocean models.
