Pb-210 dating of sediments from the central and the northern Adriatic Sea: The deposition and preservation of sedimentary organic carbon

摘要

A central goal of the ELNA project is to assess the carbon assimilation capacity of the Northern Adriatic Sea. In this study, a series of box cores were collected in order to characterize a hypothetical eutrophication gradient extending from the Po River outflow region in the north down to the shallow meso-Adriatic depression (Jabuka Pit). The main tasks assigned to IAEA-MEL were to provide Pb-210 derived sedimentation and dry-mass accumulation rates and to examine the possible correlations between sedimentary processes, the deposition and preservation of sedimentary organic carbon, and pelagic primary productivity.
