137Cs Sediment Profiles as a Tracer of Marine Sedimentation Processes in a Semi-Enclosed Bay Affected by Anthropogenic Releases—Example of Kaštela Bay (Adriatic Sea, Croatia)

Kaštela Bay was taken as a model to study sedimentation processes using the vertical sediment profiles of 137Cs massic activities. The aim distinguish conditions in different parts and partly determine pathways terrigenous input into Bay. purpose demonstrate that are applicable differentiating processes. It found mostly continuous, undisturbed takes place central south Bay; west part more complicated. is characterised by extremely slow coarse-grained or even erosion selective resuspension fine-grained particles followed resedimentation other also observed upper 10 cm most exposed homogenisation. strong influence Jadro River anthropogenic activities east reflected higher activities, mixing, increased input. This shows can provide comprehensive insights for whole region when sophisticated sampling layout deployed. results aquatic environments with comparable sedimentary environments.
