AbstractBiogeochemical processes and environmental conditions that lead to the preservation of organic matter (OM) in coastal and marine sediments has been the subject of a wealth of studies in the last decades (Hedges et al., 1999). It is estimated that more than 80% of the total organic carbon preserved in marine sediments is buried in deposits along the continental margins in >terrigenous-deltaic> regions near river mouths. In such semi-enclosed scenarios, significant environmental changes, such as climatic warming, flooding caused by an increase in the riverine water discharge or alteration of the sea level may be reflected in the characteristics of organic carbon supplied to and buried in their sediments.
