Actual Sedimentation on the Antarctic Continental Shelf (Southern Part of the Ross Sea)

During the austral summer 1994-95 the C.L.I.M.A. Project carried out an oceanographic cruise aimed at improving the caracterization of water masses inside the Ross Sea. A series of 154 CTD casts was performed and water samples were collected to study particulate matter, concentration data and dimensional analyses of particulate matter were correlated with physical characteristics. In the area of the Ross Ice Shelf high concentrations of particulate matter seem to coincide with the caracteristics of “Deep Ice Shelf Waters” and “Warm Core Waters”. The relationship between water masses and characteristics of particulate matter have enabled us to use this one as a natural tracer to identify flow pathways; results have also allowed to define a general hypothesis on actual sedimentation during the austral summer in the proximity of the RIS and at the edge of the continental shelf.
