Última Activity of the turbidite levees of the Celtic-Armorican margin (Bay of Biscay) during the last 30,000 years: Imprints of the last European deglaciation and Heinrich events ArchiMer Toucanne, Samuel; Zaragosi, S; Bourillet, Jean-francois; Naughton, F; Cremer, M; Eynaud, F; Dennielou, Bernard. High-resolution sedimentological and micropaleontological studies of several deep-sea cores retrieved from the levees of the Celtic and Armorican turbidite systems (Bay of Biscay - North Atlantic Ocean) allow the detection of the major oscillations of the British-Irish Ice Sheet (BIIS) and 'Fleuve Manche' palaeoriver discharges over the last 30,000 years, which were mainly triggered by climate changes. Between 30 and 20 cal ka, the turbiditic activity on the Celtic-Annorican margin was weak, contrasting with previous stratigraphic models which predicted a substantial increase of sediment supply during low sea-level stands. This low turbidite deposit frequency was most likely the result of a weak activity of the 'Fleuve Manche' palaeoriver and/or of a...

The Pleistocene has been period of fluctuating climate accompanied by prominent sea-level lowstands during the glacial intervals, when massive continental ice sheets extended from mountainous to lowland European areas. The retreat of the shoreline on the extensive present-day shallow continental shelf of the southern part of the British Isles induced the appearance of the 'Fleuve Manche' palaeoriver, one of the largest systems that drained the European continent. Sedimentary records from the Bay of Biscay offer an independent record allowing the reconstruction of the freshwater and sediment discharges of the 'Fleuve Manche', and the possibility of detecting the imprint of surrounding ice-sheet oscillations and attendant modification of hinterland drainage...
