The development of an Arctic ice stream-dominated sedimentary system: The southern Svalbard continental margin
Project objective: to understand of the evolution of glacial continental margins and the relationships with the changes in ice sheet dynamics induced by climatic changes.
Project founding principles:  During glacial periods, when the sea level was on average 120 m lower than it is today, the polar ice sheets expanded from the continental areas to the now submerged continental shelves, with their base grounded on the seafloor at times during glacial maxima reaching out to the continental shelf edge. Ice streams, the fast flowing parts of the grounded ice, have shaped the seafloor with glacial lineations and other mega-scale morphologic imprints. Such morphologic signature, and the marine sediments associated with them retain the information on the past ice sheet dynamics during glacial advances, on the dynamics of glacial retreat during periods of deglaciation, and on the associated paleo-oceanographic conditions.
Project methodology: Field data acquisition with multibeam swath mapping, sub-bottom profiling, seismic reflection profiling, and sediment coring.
