Relative contribution of climatic forcings and sedimentary processes in the spatio-temporal distribution of sediments in the Northern seas (Norwegian, Greenland and Barents seas)
This study focuses on the study of the Middle Pleistocene to Late Quaternary sedimentation patterns and palaeoenvironmental conditions of the Nordic seas (Barents, Iceland, Norwegian and Greenland seas), which mark the transition between the North Atlantic and the Arctic oceans. It is based upon a c...

description |
This study focuses on the study of the Middle Pleistocene to Late Quaternary sedimentation patterns and palaeoenvironmental conditions of the Nordic seas (Barents, Iceland, Norwegian and Greenland seas), which mark the transition between the North Atlantic and the Arctic oceans. It is based upon a compilation of acoustic data (bathymetry, multibeam imagery) and sedimentological data (calypso piston cores) retrieved during two cruises leaded by the Shom institute. Sedimentary records showed a large variability of the sedimentary processes at play in those seas, depending of the climatic stages and, thus, of extension or decay conditions of the surrounding ice-sheets. Glacimarine, contouritic, hemipelagic and gravity sedimentary facies are recorded in those sedimentary archives. High resolution stratigraphy was obtained using a combination of radiocarbon datings, XRF geochemistry, oxygen isotopic data and biostratigraphy. This allowed to investigate the sedimentary inputs and processes occurring in those seas from the Middle Quaternary (the beginning of the Mid-Pleistocene Transition) to the Late Holocene. It also allowed a better characterization of the variation in the boreal ice-sheet extension, and to identify periods of Atlantic Waters influence over the core sites. Ce travail présente une analyse des environnements sédimentaires marins profonds des mers nordiques à l’interface de l’Atlantique nord et de l’Arctique (mers du Groenland, de Norvège, de Barents et d’Islande) au cours du dernier million d’années. Il se base sur une base de données acoustiques (bathymétrie, imagerie multifaisceau) et sédimentologique (carottes calypso) issues de deux campagnes réalisées par le Shom. Les enregistrements sédimentaires ont montré une très grande variabilité des processus de sédimentation en jeu dans ces mers en fonction des périodes climatiques, avec notamment une sédimentation glaciomarine, gravitaire, contouritique, et hémipélagique. Ils ont également permis de se concentrer sur la chronologie des périodes de ... |
