Argo Float

Argo Floats: Observing the oceans in real time
Argo is the name of an array of floats that have eventually become the “eyes” of the scientists inside the world’s oceans.More than 3000 autonomous floats have been deployed during the last decade into the seas and oceans of the world. These floats are designed in order to submerge up to 2000m depth and emerge periodically due to a dynamic buoyancy system. The data collected are profiles of temperature, salinity, sea pressure and deep currents. Furthermore a lot of new floats have the capacity of measuring a variety of biochemical parameters such as chlorophyll and dissolved oxygen. Once the float comes to the sea surface, transmits the collected data to data centers through satellite connection. Argo data, especially in conjunction with satellite measurements, are creating new ways to view the ocean’s basic physical properties.

The Argo Network

Euro-Argo and the Mediterranean Sea






The collection of information from inside the oceans has been upgraded radically through the Argo project. Operational forecasting and long term ocean monitoring have been stepped up in Europe with the contribution of the Euro-Argo research infrastructure which is the European component of the Argo program. Euro-Argo ESFRI project will optimize the European contributions to ARGO aiming to consolidate and strengthen existing national contributions to the infrastructure and to develop new partnerships. The 1st Euro-Argo Users Meeting was held at Southampton NOCS (June 2008) with the participation of HCMR. The main discussion was how to evaluate and improve the European contribution to the Argo data management and delivery system. Furthermore it was discussed how to enhance European float technological capabilities (performance, sensors, communication systems) and work towards using Argo to study aspects of ocean biogeochemistry. Greece is actively involved in the Euro-Argo project. Monitoring the Mediterranean Sea climate and forecasting the Mediterranean Sea circulation are focal points of the Greek Operational Oceanography. As a matter of fact the POSEIDON system routinely assimilates the ARGO temperature and salinity profiles on a weekly basis in order to improve the hydrodynamical forecasts at the Mediterranean scale.
