These maps show the residence time (RT) isolines in the Mundaú/Manguaba Lagoon Estuary Complex (CELMM), located on the coast of Alagoas state, Brazil. These isolines are associated with wind and freshwater discharge and affect water renewal processes as well as salinity levels and water temperature. As shown in the map, the region near the inlets and in the channel’s residence time was low and less than 10 days. In the back area of the lagoon, the residence time is high with a significant spatial variation. These areas of low circulation are important to identify since they are potentially susceptible to pollutant accumulation.
