- After my return from the winter over in Dumont d’Urville, in May 1968, I have been engaged by Centre National pour la Recherche Scientifique (CNRS) to go on working for Groupe de Recherche Ionosphérique (GRI).
- In autumn 1968, I went to take over from the responsible of the ionosphere station of Ouagadougou (Upper Volta, now Burkina) during his six-month holidays. Then I participated, as technical responsible, in the construction of a receiving station for Canadian artificial satellites designed to study the ionosphere.
- End of 1970, we made a three-month campaign at Dumont d’Urville to install this station.
- End of 1971, I went one more time to Dumont d’Urville for a three-month summer party to modernise this station, replacing some units that had been recuperate, because of limited initial budget, from older stations no longer in use.
- On December 1st 1972, I leave Paris Orly for a fourth sojourn in Antarctica. During that new campaign, estate 1972-1973, will take place the scientific experiment CITADEL. The scope of this experiment under the scientific responsibility of Jean-Jacques Berthelier, researcher at GRI, is to study the electric field inside the ionophere, near the magnetic South Pole. This Pole lies in the vicinity of Dumont d’Urville base. Measurements will be made using stratospheric balloons, drifting at the altitude of 30 km, launched from the French base.
