Abstract

This study aimed to evaluate biogeochemical cycles (C, Si, N, and P) in a fixed station in the Cananéia-Iguape estuarine system, verifying interactions among physical and biogeochemical processes, and particle fluxes, which was measured by a cylindrical sediment trap. The result interpretation raised relationships between particle fluxes and nutrient fluctuation, what can be an important data both to reveal the limiting nutrient and the carbon fluxes at estuary water column.
