Abstract

In the 1960s, the growing strategic importance of ocean exploration led the French government to develop greater capacity in marine scientific research, aiming to promote cooperative and diplomatic relations with the leading states in ocean exploration. Devised during Charles de Gaulle's government (1958–1969), the restructuring of French oceanography culminated, in 1967, in the establishment of the state‐led Centre National pour l'Exploitation des Océans (CNEXO). Beyond being intended to control the orientation of marine research at a national level, the CNEXO's mission was to use scientific diplomacy to balance a desire for enhancing international cooperative relations in oceanography with French ambitions to equal the USA's leading capacity to explore the oceans. Its director, the naval officer Yves la Prairie, played a crucial role in articulating scientific, national, and diplomatic interests for France in the oceans.
