caract\u00e9rise par un balancement saisonnier m\u00e9ridien des vents et des pr\u00e9cipitations \u00e0 l\u2019origine d\u2019hivers secs et d\u2019\u00e9t\u00e9s humides sous les tropiques. Ce syst\u00e8me est engendr\u00e9 par la diff\u00e9rence thermique qui se cr\u00e9\u00e9e saisonni\u00e8rement entre l\u2019oc\u00e9an et le continent et entre les deux h\u00e9misph\u00e8res. Il joue ainsi un r\u00f4le essentiel dans la distribution globale de chaleur et d\u2019humidit\u00e9. Les \u00e9tudes pal\u00e9oclimatiques montrent que la dynamique des syst\u00e8mes r\u00e9gionaux de mousson a vari\u00e9 au cours du temps et notamment au cours du Quaternaire en fonction des param\u00e8tres orbitaux de la Terre et du for\u00e7age de l\u2019insolation. Il s\u2019av\u00e8re que des processus complexes et des interactions impliquant par exemple l\u2019\u00e9tendue des calottes de glaces, les changements de pCO2\u00a0atmosph\u00e9rique, et la dynamique de l\u2019oc\u00e9an, ont \u00e9galement contribu\u00e9 \u00e0 la variabilit\u00e9 de la dynamique de la mousson au cours du temps. Or, sur les continents, les variations pass\u00e9es des r\u00e9gimes de pr\u00e9cipitation et de vent d\u00e9terminent la vuln\u00e9rabilit\u00e9 des roches \u00e0 l\u2019\u00e9rosion en influant sur le d\u00e9bit des fleuves, le type de v\u00e9g\u00e9tation et les types de sols. Elles affectent ainsi l\u2019alt\u00e9ration chimique des zones sources, la mobilisation du mat\u00e9riel s\u00e9dimentaire sur les continents ainsi que son transfert fluviatile et\/ou \u00e9olien jusqu\u2019aux bassins oc\u00e9aniques. Dans les oc\u00e9ans, elles g\u00e9n\u00e8rent d\u2019importants changements dans la dynamique des eaux de surface et notamment dans la profondeur de la thermocline\/nutricline, qui impactent consid\u00e9rablement les producteurs primaires (coccolithophores notamment). C\u2019est dans ce contexte que l\u2019\u00e9tude multi-outils (s\u00e9dimentologique, min\u00e9ralogique, g\u00e9ochimique et micropal\u00e9ontologique) d\u2019archives s\u00e9dimentaires pr\u00e9lev\u00e9es dans les contextes de mousson africaine, indienne et asiatique nous permettent d\u2019aborder sous diff\u00e9rents aspects, la question de la variabilit\u00e9 du syst\u00e8me de mousson, et ceci \u00e0 diff\u00e9rentes \u00e9chelles spatio-temporelles.<\/p>\n<\/div><div class=\"fusion-text fusion-text-2\"><p><strong>Objectifs du Th\u00e8me<\/strong>\u00a0: Nos activit\u00e9s de recherche portent sur l\u2019\u00e9tude de la variabilit\u00e9 de la dynamique du syst\u00e8me de mousson dans les diff\u00e9rentes r\u00e9gions tropicales du globe au cours du Quaternaire terminal.
