Diffusive fluxes of dissolved nutrients at the sediment-water interface in Makirara Bay (Central Dalmatia, Croatia)

The biogeochemical cycles of nutrients in coastal regions exhibit some peculiarities compared to those in open ocean basins. Coastal areas are directly exposed to anthropogenic pollution. The productivity of biomass is higher and a significant part of primary production takes place within the sediment; however, a high sedimentation rate increases the preservation rate of organic carbon in the sediment. The coastal situation is furthermore specific because of terrigenous input of sedimentary organic matter that is less enriched in N and P than marine detritus, suggesting that coastal zones are a more efficient sink for carbon than for other nutrients. However, the organic-rich coastal sediment is also an important source of dissolved carbon, at least for the bottom water mass. The aim of our work was to quantify the diffusive benthic fluxes of dissolved inorganic carbon (DIC), nitrogen, phosphorus, and sulphur at the sediment/water interface in a shallow coastal area, as well as to estimate the source of DIC efflux from the sediment using isotope techniques.
