Resumo: | Turbidite systems are accumulations of fluvial sediment on the continental margins. They are mainly made of « turbidites » deposited after the flow of turbidity currents inside submarine canyons and channels. Their structure and composition are controlled by global and regional environmental changes such as sea level and climate. The two fundamental parameters that govern their functioning are the production of sediment in the river watersheds and the capability and reactivity of the transfer to the turbidite system. In this work we show that for the last 24,000 years the functioning of the Rhone turbidite system has shown rapid changes under the control of sea level and sediment production fluctuations. Our results are based on a millennial time-scale chrono-stratigraphy obtained on turbidites collected in sediment cores during the RHOSOS and other cruises.
