SEASONAL AND PLURI-ANNUAL VARIABILITY OF SEDIMENT ACCUMULATION AND ORGANIC MATTER FLUXES IN THE NORTHWESTERN ADRIATIC SHELF AND ITS RELATIONSHIP WITH THE FRONTAL SYSTEM

Twenty eight short sediment cores, collected along six transects in two areas influenced by the frontal system formed by the Po River, were analysed for Th-234 and Cs-137 in order to improve our knowledge on short time scale sediment deposition, accumulation and mixing. Sedimentological and mineralogical parameters were also analysed.
