Objective The major scientific objective of the MAGELLAN-TEAHITIA experiment which took place between the end of March and mid-June 1989 was to determine the electric conductivity structure of the hotspot of Teahitia, named after one of the volcanoes in the Society Islands archipelago in French Polynesia, in order to draw up distribution models of temperature and partial melting. The results will be discussed in the broader context of hotspot formation and their mantle convection. The second objective was to make a preliminary study of mean ocean circulation in the zone studied, to characterise the amphidromic point of the tide's M2 component and to present the TOPEX/POSEIDON experiment based on collected data and altimetric measurements by the GEOSAT satellite.
