In 2022, four pairs of Argo floats where deployed in the Caribbean Sea during a cruise of the Dutch researach vessel Pelagia. Each pair consists of one Dutch and one French float, both equipped with sensors from  two different manufacturers. These deployments serve to enable a comparison between these two sensor types.
