Última Les surcotes et les décotes marines à Brest, étude statistique et évolution ArchiMer Bouligand, R; Pirazzoli, Pa. Sea surges (positive or negative) are short-period events (several hours to several days) among the most extreme oceanic phenomena resulting from climatic variability. A statistical study of hourly tide-gauge records at Brest does not allow any clear trend in long-term variations of these extreme sea levels to be detected. However, the frequency of extreme positive sea surges has increased recently (1953-1994), whereas extreme and sub-extreme negative sea surges has decreased. Such trends for the highest values strengthen the prevalence of positive sea surges over negative ones. The general evolution appears to be organised around several time scales, with a strong interannual variability superimposed on periods of amplification or regression of decennial...

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...
