Argo floats are autonomous robots, equipped with sensors to measure the temperature and salinity of water up to 2000 meters deep. Today they are essential for operational oceanography and building more and more knowledge about global warming and marine currents. They constitute a global network but their level of deployment in numbers is still insufficient in certain strategic areas, such as currently in the South Atlantic,
The choice of day and the deployment area were carefully chosen according to the actual weather conditions to ensure risk-free operations for sailors and their boats. The targeted drop zone is located between latitudes 20°S and 40°S , before passing the Cape of Good Hope. This region, where the density of Argo floats is lower, is crucial to enriching the understanding of global ocean dynamics.
