The Sacca di Goro is an eutrophic lagoon located along the North Adriatic Coast of Italy. This lagoon has been investigated using monthly averaged data from the last decade. Water, salt and nutrient budgets were estimated using LOICZ (land ocean interactions in the coastal zone) methodology with a single layer approach.

Concerning water and salt budgets a mean freshwater residence time of 24.5 days was obtained, whereas the total water exchange time has a mean value of 1.5 days or 3.4 days depending on the data and the model used. Furthermore, the value has oscillated strongly during the last twenty years due to the morphological changes that the Sacca di Goro mouth has experienced in the last decades.

Non-steady state DIP and DIN budgets have been established at seasonal intervals between 1989 and 1998. Whereas the mean delta-DIP values follow several yearly trends depending on the seasonal values for macroalgal biomass, riverine inputs and lagoon concentrations; delta-DIN has been predominantly negative during the last decade indicating that the Sacca di Goro has been a sink of inorganic nitrogen, however at the beginning of 87 and at the end of 97 the Sacca di Goro has acted as a source, with positive delta-DIN. More data is necessary to see if there is a reversal in the general trend. nd.
