Mesure du couple tritium/hélium océanique par spectrométrie de masse IRD
Jean-Baptiste, P.; Andrié, Chantal; Lelu, M..
Nous décrivons la technique expérimentale de mesure des isotopes de l'hélium (3he et 4he) dans l'eau de mer par spectrométrie de masse ainsi que la méthode de dosage du tritium océanique par analyse de l'hélium-3 de décroissance. Les protocoles analytiques sont reportés ainsi que la précision de chacune des méthodes. Enfin, l'intérêt de l'acquisition du couple de données hélium-3/tritium est explicité au travers de la détermination de "l'âge" d'une masse d'eau. (Résumé d'auteur)

The distribution of helium 3 in the deep Western and Southern Indian Ocean IRD
Jamous, D.; Mémery, L.; Andrié, Chantal; Jean-Baptiste, P.; Merlivat, L..
Almost a decade after the Geochemical Ocean Sections Study Indian Expedition, the new deep 3He data from the INDIGO program give a further insight into the distribution of this tracer in the Indian Ocean. This distribution exhibits some major features related on one hand to a hydrothermal 3He input in the Gulf of Aden and on the Mid-Indian Ocean Ridge, and on the other to the origin of the water masses and to the characteristics of the deep circulation.

Tritium and helium 3 in the northeastern Atlantic ocean during the 1983 Topogulf cruise IRD
Andrié, Chantal; Jean-Baptiste, P.; Merlivat, L..
This study is part of the TOPOGULF program, in which tracer measurements were closely associated with the hydrological data. The sampled area was located near the Azores Islands on the both sides of the mid-Atlantic ridge. The tritium content of the surface waters reveals a strong front along the Azores current. The 3He distributions are used to identify some areas where ventilation processes are active. At depth, the spatial distribution of tritium is studied along isopycnals. In the thermohaline it is essentially the anticyclonic gyre which is responsible for the northeast-southwest gradient in tritium concentrations. The respective influence of the Labrador sea water and the Mediterranean water seems to be ain end member responsible for a decrease of...
