Monitoring and analysis of water, salt and nutrient fluxes at the mouth of a lagoon

An intensive sampling program of physical and chemical parameters has been undertaken at Vassova lagoon, northeast Greece, in order to examine water circulation and estimate the instantaneous and residual fluxes of water, salt and nutrients through the entrance canal of this lagoon. Field data of hydrographic and water quality parameters were collected under neap and spring tidal cycles, and under Winter and summer conditions, to account for the fortnight and seasonal effects in the lagoon. The analysis showed that the Eulerian residual transport and the Stokes drift are positive in direction, thus pushing water, salt and nutrients inward Vassova lagoon.
