Argo is a global array of 3,000 free-drifting profiling floats that measures the temperature and salinity of the upper 2000 m of the ocean. This allows, for the first time, continuous monitoring of the temperature, salinity, and velocity of the upper ocean, with all data being relayed and made publicly available within hours after collection.


Since Argo data are made freely available we ask that where Argo data are used in a publication or product, the following acknowledgement is given:

" These data were collected and made freely available by the International Argo Project and the national programs that contribute to it. (, Argo is a pilot program of the Global Ocean Observing System."

If you plan to use or are using Argo data, the Argo Steering Team requests that, as a courtesy, you inform the groups responsible for the floats that you are using of the type of study you are undertaking. You can find who to contact by going to to the quick link "Find floats" and enter the WMO or Telecom ID.
