In the very final part of the Gulf, along the Cilento hill formations, the coast resumes a rocky morphology, in correspondence to the Area Marina Protetta Santa Maria di Castellabate, where pristine waters are present. The GOS is characterized by less hydrographic and biological gradients as compared to the GON. The rivers and some secondary outlets represent the main source of nutrients, draining the cultivated fields and carrying the urban sewage discharges. Nutrient concentrations in the Gulf of Salerno are generally lower than those reported for the GON (Marino et al., 1984). are generally lower than those reported for the GON (Marino et al., 1984).
